Semiconductor chips are composed of many microscale layers that are smaller than a fingernail and thinner than paper. The semiconductor is stacked high and dense, forming complex structures similar to high-rise buildings. To create such structures, the following steps need to be repeated multiple times: lithography ……

In the previous article, we introduced the photolithography process, which uses a photomask to project the designed circuit patterns onto the surface of the wafer coated with photoresist. The next step is to perform the etching process on the wafer to remove unwanted material and retain only the desired pattern.

In previous articles, we introduced wafer fabrication, oxidation processes, and a partial history of integrated circuits. Now, let's continue to explore the photolithography process, which transfers the electronic circuit patterns onto the wafer. Photolithography is similar to taking photographs with a film camera, but……

During the "oxidation" step, an oxide layer (SiO₂) is formed on the surface of the wafer. The wafer is the most important material in semiconductor processing. The oxide layer protects the surface of the wafer from impurities, and the next step is to design the semiconductor circuit. What does the circuit in a semic……

Semiconductors have become an essential part of our lives. Today, we return to the "Eight Basic Semiconductor Processes" series to continue exploring semiconductor manufacturing processes. In the previous article, we learned about the wafer manufacturing process. In this article, we will introduce the oxidation process……

Could our lives last a day without semiconductors? Many aspects of our daily lives, including smartphones, laptops, cars, televisions, and credit cards, are inseparable from semiconductors. These semiconductors have a profound impact on our lives. So, how are they made?

If you are interested in the semiconductor industry, it is crucial to have a solid understanding of the "eight basic semiconductor manufacturing processes." We have prepared a series of articles about semiconductor manufacturing processes for those who need to review or improve their knowledge on this topic. We will in……

In the current IGBT surface structure, planar and trench types can be said to be evenly matched. When many readers first encounter these two terms, they may mistakenly think that the current of the planar IGBT flows horizontally, while the current of the trench-gate IGBT flows vertically. In fact, this is a misundersta……

VII. Future Development Trends 7.1 Smaller process nodes One of the main trends in future lithography is towards smaller process nodes. Semiconductor manufacturers have been pursuing smaller and more compact electronic components for improved perfor

In the modern world of technology that surrounds us, tiny electronic chips have become an essential part of our daily lives. Whether it's our smartphones, computers, or various electronic devices, their interiors hide small yet powerful electronic components that play a crucial role in semiconductor manufacturing. Howe……

Is it true that Japan's semiconductor companies lag far behind those of other countries, particularly those represented by South Korea's semiconductor industry, due to factors such as poor management by Japanese companies and ineffective policies
