China graphite heat transfer Manufacturers, Suppliers, Factory

Porous graphite, also known as porous carbon or porous graphite material, is a graphite form that has been specially engineered to have an interconnected network of pores or voids within its structure.

Recently, our company announced that the company has successfully developed a 6-inch Gallium Oxide single crystal using the casting method, becoming the first domestic industrialized company to master the 6-inch Gallium Oxide single crystal substrate preparation technology.

MOCVD is a new vapor phase epitaxial growth technology developed on the basis of vapor phase epitaxial growth (VPE).

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 paper provides a comprehensive overview of the various manufacturing techniques employed to produce dense SiC ceramics, highlighting their unique characteristics and applications.

Semiconductor materials are the materials with electrical conductivity between conductors and insulators at room temperature, which are widely used in fields like integrated circuits, communications, energy and optoelectronics. With development of technology, semiconductor materials have evolved from the first generation to the fourth generation.
