Photomask / PHOTOMASK Did you know? The billions of fine circuits on a chip rely on a “micro film” to accurately “draw” them out — this is the photomask. From 193nm deep ultraviolet to 13.5nm extreme ultraviolet, from 28nm mass production to 14nm breakthroughs, this “small slice” of quartz and chromium film hides the core … Read more
In the world of chip manufacturing, the race at the nanoscale has never ceased. As we transition from 7nm to 5nm, 3nm, and even more advanced processes, an unexpected challenge has emerged: the power delivery network is starting to occupy the front space of the chip. It’s like a bustling city where utility poles and … Read more
Imagine you are building a miniature city, where the width of the roads is only a thousandth of a hair, and the size deviation of each building must be less than a few atoms—this is the challenge faced by modern chip manufacturing. Among these, the Critical Dimension (CD), such as the narrowest gate width in … Read more

Introduction: She was rejected by a chip factory just for saying “photoresist is a photosensitive material” Last week, I had milk tea with Xiaoxia, who recently switched jobs. She held her iced coconut milk and sighed, “Sister, I interviewed at XX chip manufacturing company, and when the HR asked me ‘What is photoresist?’, I replied … Read more
In January 2024, the Ministry of Industry and Information Technology released the “Guidelines for the Construction of National Automotive Chip Standard System,” which stipulates that automotive chips for core components, including power and chassis control systems, intelligent driving assistance systems, and battery management systems, must use automotive-grade chips. However, there are no strict regulations in … Read more
Chip manufacturing’s “final step”: Unveiling the mysterious “tape-out” and its high costs In the world of chips (integrated circuits), there is a crucial step that determines whether the hard work of countless engineers can be transformed from blueprints into reality, and that is—”tape-out”. What does this industrial-sounding term really mean? Why is it often said … Read more
On July 31, according to Reuters, semiconductor IP giant Arm announced its second-quarter financial forecast, which fell short of market expectations.
