As global acceptance of electric vehicles gradually increases, Silicon Carbide (SiC) will encounter novel growth opportunities in the forthcoming decade. It is anticipated that manufacturers of power semiconductors and operators in the automotive industry will participate more actively in the construction of this sector’s value chain.

The processing of 4H-SiC substrate mainly includes the following steps:

Silicon Carbide generally uses the PVT method, with a temperature of more than 2000 degrees, a long processing cycle, and low output, so the cost of Silicon Carbide substrates is very high.

Currently, many semiconductor devices employ mesa device structures, which are predominantly created through two types of etching: wet etching and dry etching. While the simple and rapid wet etching plays a significant role in semiconductor device fabrication, it has inherent drawbacks such as isotropic etching and poor uniformity, which result in limited control when transferring small-sized patterns. Dry etching, however, with its high anisotropy, good uniformity, and repeatability, has become prominent in semiconductor device fabrication processes. The term “dry etching” broadly refers to any non-wet etching technology used for removing surface materials and transferring micro and nano patterns, including laser etching, plasma etching, and chemical vapor etching. The dry etching discussed in this text specifically pertains to the narrow application of processes using plasma discharge—either physical or chemical—to modify material surfaces.

This article delves into the usage and future trajectory of silicon carbide (SiC) boats in relation to quartz boats within the semiconductor industry, specifically focusing on their applications in solar cell manufacturing.

Oxidation processes play a critical role in preventing such problems by creating a protective layer on the wafer, known as the oxide layer, which acts as a barrier between different chemicals.
