Download for free today: 2025 Semiconductor Industry In-Depth Report Source: Semiconductor Industry Insights Author: Feng Ning Recently, a financial report from Zhongwei Company reflects that the semiconductor equipment market’s focus is expanding beyond photolithography machines to include other core equipment fields … Read more
First, a fun fact: Making chips is like baking a cake, where the photolithography machine is the oven and the photoresist is the baking paper. Without the paper, the cake will burn at the bottom. Currently, 90% of the world’s high-end “baking paper” is printed in Japanese, and the finest types are measured in individual … Read more
In the previous two articles, we gained a preliminary understanding of the semiconductor fabrication process and left some questions unanswered. Today, let’s address three issues encountered in “Semiconductor Fabrication Processes”. If you have other opinions or views, feel free to leave comments for discussion. Q1:What are the process considerations behind the requirement for device orientation … Read more
1. Introduction: SOC (Spin-On Carbon) is a carbon-based film material deposited through a spin-coating process, primarily used in the photolithography step of semiconductor manufacturing. This technology involves applying a liquid polymer precursor with a high carbon content onto a semiconductor substrate, and then evenly distributing it by rapidly spinning the substrate to form a thin … Read more
Photolithography technology is one of the core driving forces behind the continuous miniaturization of integrated circuit chip manufacturing processes. According to the Science and Technology Daily, recently, Professor Peng Hailin’s team from Peking University’s School of Chemistry and Molecular Engineering, along with collaborators, successfully utilized cryo-electron tomography to analyze the microscopic three-dimensional structure, interfacial distribution, … Read more
1. Wafer Fabrication Plants 1.1. Advanced Processes Domestic: SMIC International: TSMC (Taiwan), Samsung (South Korea), Rapidus (Japan), Intel (USA) The gap is significant (approximately 2 generations, with SMIC achieving 7nm mass production through multiple polishing): TSMC – 3nm/5nm/7nm account for over 70% of revenue, with 2nm risk production starting this year. 1.2. Mature Processes Domestic: … Read more
Our public account has surpassed 500 followers in just over a month. We will continue to work hard and share more valuable content. Happy National Day! The key material in the photolithography process is photoresist, which mainly consists of organic resins, photosensitive compounds, and solvents. Additionally, it needs to be resistant to corrosion and ion … Read more
Part One: What is “Chip Fabrication”? We can understand it as “the first trial print of constructing an ultra-complex skyscraper”. Imagine you want to build a special skyscraper—it is a microchip with billions of “rooms” (transistors), and the design is extremely complex. If you start construction directly and make a design error, the entire “building” … Read more
Understanding semiconductors can be simplified for beginners: Semiconductor equipment materials are like blank paper, Photolithography machines are like pens, Chips are like written letters on the paper, Packaging and testing are like envelopes, CP0 is like the ink inside the pen, Software cloud computing is like the formatting methods for writing letters.
Chip tape out (Tape Out) is the core step in transforming integrated circuit design into physical chips, involving design verification, process manufacturing, and sample testing, which directly determines the success rate of chip mass production. The name originates from the early tradition of “streaming” design drawings to tapes, which has now evolved into the entire … Read more
