Product Description

SiC epitaxial wafer substrate Semiconductor industrial applications 4H-N

Product Description:

  Silicon carbide (SiC Substrate) was discovered in 1893 as an industrial abrasive for grinding wheels and automotive brakes. About midway through the 20th century, SiC Substrate uses grew to include in LED technology. Since then, it has expanded into numerous semiconductor applications due to its advantageous physical properties. These properties are apparent in its wide range of uses in and outside the semiconductor industry. With Moore’s Law appearing to reach it’s limit, many companies within the semiconductor industry is looking towards silicon carbide as the semiconductor material of the future.
  SiC Substrate can be produced using multiple polytypes of SiC, although within the semiconductor industry, most substrates are either 4H-SiC, with 6H- becoming less common as the SiC market has grown. When referring to 4H- and 6H- silicon carbide, the H represents the structure of the crystal lattice. The number represents the stacking sequence of the atoms within the crystal structure. This is described in the SVM capabilities chart below.

4H-N SiC (silicon carbide) is a semiconductor material that is widely used in high-performance electronic devices due to its excellent thermal conductivity, electrical properties and chemical stability. Especially in high temperature, high pressure or high frequency environments, the characteristics of 4H-N SiC make it an ideal choice. This material is mainly used in the manufacture of high performance power devices and electronic components such as Schottky diodes, metal-oxide-semiconductor field-effect transistors (MOSFETs) and insulated-gate bipolar transistors (IGBTs). In addition, 4H-N SiC is also used in the production of LED lights and components for high-frequency communication systems, as it can effectively reduce system energy consumption and improve overall performance and reliability.
ZMSH SIC010 is versatile and can be used in a variety of industries. Its excellent properties make it an ideal choice for high-temperature, high-power, and harsh environments. The customized plastic boxes make it easy to transport and store the silicon carbide wafers.
