The four main molding methods for graphite molding are: extrusion molding, molding, vibratory molding and isostatic molding. Most of the common carbon/graphite materials on the market are molded by hot extrusion and molding (cold or hot), and isostatic molding is a method with leading molding performance. Vibration molding is generally used to manufacture medium and coarse structural graphite, particle size between 0.5-2mm particle size, generally dominated by di-roasted graphitized products, density between 1.55-1.75kg/m³, coarser particles, rougher surface, can not be used for precision machining. It is mainly used in chemical industry and metal smelting.

In semiconductor manufacturing, atomic-level flatness is usually used to describe the global flatness of the wafer, with the unit of nanometers (nm).

A diffusion furnace is a specialized piece of equipment used to introduce impurities into semiconductor wafers in a controlled manner. These impurities, called dopants, change the electrical properties of semiconductors, allowing different types of electronic components to be made. This controlled diffusion process is critical to the production of transistors, diodes and integrated circuits.

Wafers are essential raw materials for integrated circuits, power devices, and semiconductor discrete devices. Over 90% of integrated circuits are manufactured using high-purity, high-quality wafers. The quality and supply capacity of these wafers within the industry are directly linked to the overall performance and competitiveness of integrated circuits. In this discussion, we will introduce the wafer manufacturing process in detail.

​In the realms of semiconductor technology and microelectronics, the concepts of substrates and epitaxy hold significant importance. They play critical roles in the manufacturing process of semiconductor devices. This article will delve into the differences between semiconductor substrates and epitaxy, covering their definitions, functions, material structures, and application areas.

Silicon carbide (SiC) power devices are semiconductor devices made of silicon carbide materials, mainly used in high-frequency, high-temperature, high-voltage and high-power electronic applications. Compared with traditional silicon (Si)-based power devices, silicon carbide power devices have higher bandgap width, higher critical breakdown electric field, higher thermal conductivity and higher saturated electron drift velocity, which makes them have great development potential and application value in the field of power electronics.
