China Porous Tantalum Carbide (TaC) Manufacturer, Supplier, Factory

As the 8-inch silicon carbide (SiC) process matures, manufacturers are accelerating the shift from 6-inch to 8-inch. Recently, ON Semiconductor and Resonac announced updates on 8-inch SiC production.

The Taiko process thins silicon wafers using its principles, technical advantages and process origins.

In the growth of SiC and AlN single crystals using the physical vapor transport (PVT) method, crucial components such as the crucible, seed holder, and guide ring play a vital role. As depicted in Figure 2 [1], during the PVT process, the seed crystal is positioned in the lower temperature region, while the SiC raw material is exposed to higher temperatures (above 2400 ℃).

Silicon carbide (SiC) is a high-precision semiconductor material known for its excellent properties like high temperature resistance, corrosion resistance, and high mechanical strength. It has over 200 crystal structures, with 3C-SiC being the only cubic type, offering superior natural sphericity and densification compared to other types. 3C-SiC stands out for its high electron mobility, making it ideal for MOSFETs in power electronics. Additionally, it shows great potential in nanoelectronics, blue LEDs, and sensors.

In the semiconductor manufacturing industry, as device size continues to shrink, the deposition technology of thin film materials has posed unprecedented challenges. Atomic Layer Deposition (ALD), as a thin film deposition technology that can achieve precise control at the atomic level, has become an indispensable part of semiconductor manufacturing. This article aims to introduce the process flow and principles of ALD to help understand its important role in advanced chip manufacturing.

Electron beam evaporation is a highly efficient and widely used coating method compared to resistance heating, which heats the evaporation material with an electron beam, causing it to vaporize and condense into a thin film.
