The tray (base) that supports SiC wafers, also known as a "susceptor," is a core component of semiconductor manufacturing equipment. And what exactly is this susceptor that carries the wafers?

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.

The degree of graphitization is an essential measure used to assess how close carbon atoms are to forming a tightly-packed hexagonal graphite crystal structure.

Isostatic pressing technology is a critical process in the manufacturing of isostatic graphite, largely determining the performance of the final product. As such, comprehensive research and optimization of isostatic graphite production remain essential focal points in the industry.

In the semiconductor manufacturing process, wafers form the foundation of chip production. Among these, a special type of wafer, referred to as the Dummy Wafer, plays a pivotal role in ensuring equipment stability and controlling production costs.
