In their newly released annual report, TSMC Chairman Deyin Liu and CEO Chieh-Jia Wei revealed the progress related to the 2nm process.

A P-type silicon carbide (SiC) wafer is a semiconductor substrate that is doped with impurities to create a P-type (positive) conductivity. Silicon carbide is a wide-bandgap semiconductor material that offers exceptional electrical and thermal properties, making it suitable for high-power and high-temperature electronic devices.

As the world looks for new opportunities in semiconductors, gallium nitride continues to stand out as a potential candidate for future power and RF applications. However, for all the benefits it offers, it still faces a major challenge; there are no P-type (P-type) products. Why is GaN touted as the next major semiconductor material, why is the lack of P-type GaN devices a major drawback, and what does this mean for future designs?

​In the realms of semiconductor technology and microelectronics, the concepts of substrates and epitaxy hold significant importance. They play critical roles in the manufacturing process of semiconductor devices. This article will delve into the differences between semiconductor substrates and epitaxy, covering their definitions, functions, material structures, and application areas.

The most basic stage of all processes is the oxidation process. The oxidation process is to place the silicon wafer in an atmosphere of oxidants such as oxygen or water vapor for high-temperature heat treatment (800~1200℃), and a chemical reaction occurs on the surface of the silicon wafer to form an oxide film (SiO2 film).

The push for higher power density and efficiency has become a primary driver of innovation across multiple industries, including data centers, renewable energy, consumer electronics, electric vehicles, and autonomous driving technologies. In the realm of wide bandgap (WBG) materials, Gallium Nitride (GaN) and Silicon Carbide (SiC) are currently the two core platforms, viewed as pivotal tools leading power semiconductor innovation. These materials are profoundly transforming the power electronics industry to address the ever-increasing demand for power.
