The wafer boats, loaded with a batch of wafers to be processed, are positioned on long cantilevered paddles.

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.

Graphitising is the process of transforming non-graphitic charcoal into graphitic charcoal with graphite three-dimensional regular ordered structure by high-temperature heat treatment, making full use of electrical resistance heat to heat the charcoal material to 2300~3000 ℃, and transforming the charcoal with amorphous chaotic layer structure into ordered graphite crystalline structure.

In order to introduce the SiC coated graphite susceptor, it's important to understand its application. When manufacturing devices, further epitaxial layers are required to be built on some wafer substrates.

When cleaning wafers, ultrasonic cleaning and megasonic cleaning are commonly used to remove particles from the wafer surface.

Plasma is the fourth state of matter, and it plays a crucial role in both industrial applications and natural phenomena.
