Shanghai International Convention Center, Huaxia Hall. The massive circular venue was filled to capacity, the air compressed to its limit, permeated with a special tension mixed with anticipation, scrutiny, and a sense of witnessing history. Guests from global top tech media, industry analysts, competitor representatives, investment institutions, and semiconductor associations from various countries filled every seat, with even more people standing expectantly in the back rows. Countless camera lenses, like dark, staring eyes, focused on the dazzling stage center. Today, this place would host a launch event destined to be recorded in the annals of the global semiconductor industry—the "Stringlight One" Mass Production and First 2nm Chip Global Debut Ceremony.
In the backstage lounge, Xiuxiu faced a simple makeup mirror, making final adjustments to her appearance. She wore a sharply tailored deep blue suit dress, dignified yet elegant, with a brooch designed as a beam piercing through a wafer pinned at her collar, shining brilliantly. In the mirror, her eyes were calm, her face slightly tired yet revealing a tempered resolve and composure. Ten years of trials and tribulations, thousands of days and nights of exhaustive effort, all seemed to have settled beneath this tranquility. She didn't rehearse technical details repeatedly in her mind as usual, merely quietly adjusting her breathing, as if listening to the echo deep within of finally reaching this milestone after the long technological Long March.
"Dr. Xiu, five minutes to go," staff voice came through the headset, steady yet carrying a barely perceptible excitement.
Xiuxiu nodded, taking a deep breath. The air filtered through the precision air conditioning system carried a familiar, cleanroom-like purity. She stood, walking toward the side curtain leading to the stage. The passage was somewhat dim, contrasting sharply with the intensely lit, nearly blinding area ahead. This step forward meant "Stringlight One" and the Chinese high-end lithography technology it represented would officially move from behind the scenes of laboratories and production lines to the center of the world stage, undergoing the most stringent, merciless scrutiny.
When the host announced her name and title with impassioned voice, Xiuxiu's face revealed a faint, confident smile. With steady strides, she stepped into that dazzling ocean of lights. Instantly, a tsunami of applause enveloped her, flashlights creating an almost continuous curtain of light. She walked to stage center, bowed slightly to the audience below, then lifted her head, calmly scanning the sea of dark-clad people. She saw many familiar faces—her team members, Huaxin International partners, industry seniors—and also countless unfamiliar eyes filled with curiosity, doubt, even scrutiny.
"Distinguished guests, media friends, good morning," her voice transmitted clearly through the microphone to every corner of the venue, not deliberately raised yet carrying undeniable penetrating power. "I am Xiuxiu. Today, standing here, I am honored to witness with all of you a moment belonging to China's semiconductor industry, and a new chapter in global technological collaboration."
Without excessive pleasantries, she directly cut to the topic. The massive curved screen behind instantly lit up, in a deep cosmic background, a brilliant beam like a sword pierced through darkness, finally focusing on an extremely tiny, stunningly complex three-dimensional rendered image of a chip. The image was so clear one could vaguely see densely packed forest-like transistor arrays.
"This is our first mass-produced 2nm process chip—'Zhengcheng'—based on the completely independently developed 'Stringlight One' High NA EUV lithography machine," Xiuxiu's voice carried a barely perceptible pride, but more was factual calmness.
As she spoke, the chip image on screen began decomposing, magnifying, revealing its internally breathtaking microscopic structures. "Next, I will report to everyone the key performance indicators of the 'Zhengcheng' chip."
The venue fell into complete silence, everyone holding their breath, awaiting those numbers that would determine the future landscape of the technology industry.
"First, **transistor density**." The screen behind Xiuxiu displayed precise data and comparison charts. "On the 'Zhengcheng' chip, we achieved highly integrated **333 million** transistors per square millimeter." This number was bolded and enlarged, eliciting the first wave of low exclamations below. She further explained, "This benefits from the higher resolution and more precise graphical fidelity provided by 'Stringlight One's' High NA technology, enabling us to create smaller, denser transistor structures. Particularly, we adopted a completely new **Gate-All-Around transistor** architecture, achieving more effective current control in three-dimensional space, fundamentally overcoming the physical bottlenecks traditional FinFET transistors face at higher densities."
The screen displayed structural comparison animations of Gate-All-Around versus traditional FinFET transistors, clearly showing how the GAA structure wraps the conductive channel from all directions, providing superior electrostatic control, thus allowing further transistor size scaling.
"Second, **power consumption**." Xiuxiu switched slides, showing complex power consumption curves and energy efficiency ratio data. "Under equivalent performance loads, the 'Zhengcheng' chip's same-performance power consumption is reduced by **45 to 50 percent** compared to the current industry's most advanced process." This number again elicited murmurs. She elaborated in detail: "This is mainly attributed to three aspects: first, the low leakage current brought by Gate-All-Around transistors themselves; second, our innovative **backside power delivery network** technology." The screen displayed a chip cross-section animation, showing how power delivery lines could be transferred from the "front side" of transistor interconnect layers to the "back side" of the wafer, greatly reducing resistance and performance losses from power lines, releasing precious front-side routing resources while improving power delivery efficiency; "Third, our breakthroughs in low dielectric constant dielectric materials and high conductivity interconnect metal materials, effectively reducing capacitance and resistance losses from internal chip wiring."
"Third, **frequency**." Xiuxiu announced the final key indicator. "In laboratory environment, the 'Zhengcheng' chip's maximum operating frequency has surpassed **5.2 GHz**, and under conventional cooling conditions, can stably operate in the high-performance range above 4.8 GHz." She added, "This is not only due to the transistors' own speed, but also inseparable from our optimized interconnect technology and advanced packaging solutions. We adopted **wafer-level packaging** and **hybrid bonding** technology, significantly improving signal transmission speed and bandwidth between different functional modules within the chip, and between chip and external packaging, reducing latency."
Transistor density, power consumption, frequency—these three most core indicators, like three solid pillars, together support the 'Zhengcheng' chip's position in the global top chip arena. Data doesn't lie; they clearly indicate that China not only masters EUV lithography machine manufacturing—this crown jewel—but also reaches shoulder-to-shoulder or even partially leading levels in chip design and process integration compared to the world's best.
Next, Xiuxiu demonstrated the 'Zhengcheng' chip's application potential in several key fields. In artificial intelligence, its ultra-high transistor density and energy efficiency ratio provide hardware foundation for deploying larger-scale, more complex neural network models, whether for cloud training or edge inference, bringing significant performance improvements and energy consumption reductions. The screen demonstrated AI servers based on 'Zhengcheng' chips showcasing overwhelming advantages compared to existing platforms when processing ultra-large natural language models and computer vision tasks.
In high-performance computing, its high frequency and high bandwidth characteristics make it ideal computing cores for constructing next-generation exascale supercomputers. Animations simulated future supercomputing centers equipped with tens of thousands of 'Zhengcheng' chips, potential breakthroughs in climate simulation, new material discovery, astrophysics, and other major scientific questions.
In mobile communication and IoT, its low power consumption characteristics mean longer device battery life and broader application scenarios. From smartphones to autonomous vehicles, from smart cities to wearable devices, the 2nm technology represented by 'Zhengcheng' chips will become the core engine driving their development.
As the demonstration concluded, the venue erupted into prolonged, enthusiastic applause. Within this applause were admiration, recognition, and respect competitors had no choice but to give. Lights refocused on Xiuxiu standing calmly at stage center, welcoming the next segment—media Q&A.
The first question came from a senior editor of Nature Electronics: "Dr. Xiu, this is an astonishing achievement. I wonder, what was the greatest challenge you encountered during the development of 'Stringlight One' and the 'Zhengcheng' chip? How did you personally persevere?"
Xiuxiu nodded slightly, pondered a moment, then responded: "Challenges were everywhere. From EUV light source power stability, to thermal deformation control of optical systems, to integration and yield enhancement of thousands of process steps in chip manufacturing... each link was like climbing a snow-capped mountain with an invisible peak." Her voice was calm yet contained strength. "As for perseverance... I think it stems from a belief—a belief unwilling to lag behind others, hoping to use our own wisdom and hands to contribute strength to the nation, to the world. Of course, it's also inseparable from support from an exceptional team, and..." She paused, her gaze seemingly penetrating the venue's lights, looking toward somewhere farther, her voice becoming softer yet deeper, "...and some very important partners. Here, I'd like to especially thank two people who gave irreplaceable support to me personally and to the 'Stringlight' endeavor."
The venue instantly became quieter, everyone perking up their ears.
"One is the mathematician far away at Princeton, Professor Yue'er." Xiuxiu's voice was clear and firm. "It is her, using the deepest mathematical wisdom, who provided the intellectual lighthouse for our understanding complex systems and optimizing algorithms. Especially in computational lithography and defect analysis, her theories guided our direction forward. She is the indispensable 'mathematical brain' behind us."
A wave of subtle discussion rippled below, many faces showing surprised expressions. Directly linking theoretical mathematicians with cutting-edge chip manufacturing was rare in previous tech launch events.
"The other," Xiuxiu continued, her face revealing a complex, grateful smile, "is Mr. Mozi. Not only did he provide crucial capital support when we most needed it, more importantly, with unique vision and boldness, he constructed a financial ecosystem supporting technological innovation and industrial transformation. He is the 'capital heart' enabling us to focus wholeheartedly on technological breakthroughs."
"Mathematical brain" and "capital heart"! These two highly symbolic terms were publicly and solemnly raised by Xiuxiu on such a globally watched occasion, undoubtedly the highest-profile affirmation of the unique, solid "iron triangle" relationship among the three of them. This was no longer privatetacit understanding but declaration to the whole world—behind this technological miracle was a new paradigm of deep integration and synergisticsymbiosis of mathematics, technology, and capital.
The venue erupted in uproar, followed by thunderous applause again, this time carrying more curiosity and inquiry. Journalists recorded rapidly, camera lenses tightly capturing every subtle expression on Xiuxiu's face.
Subsequent questions ranged from sharp, professional, to future planning. Xiuxiu responded one by one, precise in wording, clear in logic, showcasing both the professional competence of a technology leader and the warmth and grace of an Eastern woman. She discussed continuous R&D investment, industry chain collaboration, attitude toward open cooperation, also candidly mentioned challenges still faced—like further cost control, exploration of more advanced processes, etc.
When the closing music of the launch event sounded, Xiuxiu bowed to the audience below once more. The applause was unceasing, like tidal waves encircling her. She stood at stage center, bathed in glorious spotlight, her face still maintaining that composure and calmness.
Only she herself knew what emotional turbulence surged beneath this tranquility. Ten years of hardships transformed into today'sconfidence standing atop the world; team's sweat condensed into thosecold yet scorching data on screen; and that precious understanding and supporttranscendingdiscipline and domain boundaries... everything received its response at this moment.
She walked off stage, temporarily isolating thetumult and glory behind. The passage remained dim, yet her heart wasclarity with light. She knew this was merely a new starting point. The global debut of "Stringlight One" and the "Zhengcheng" chip was not an end, but a resounding clarion call for China's semiconductor industry ascending toward higher peaks. She, and her partners, would continue firmly walking forward on this challenging and glorious path.
