Heat treatment is one of the essential and important processes in the semiconductor process. Thermal process is the process of applying thermal energy to a wafer by placing it in an environment filled with a specific gas, including oxidation/diffusion/annealing, etc.

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.

Carbon/carbon composite materials refer to composite materials composed of carbon fiber reinforcement and carbon-based matrix. They have the characteristics of low density, high strength, high specific modulus, low thermal expansion coefficient, etc. Their super high temperature resistance makes them the most promising high-temperature material.

Chemical Vapor Deposition (CVD) is a versatile technique for producing high-quality coatings with various applications in industries such as aerospace, electronics, and materials science. CVD-SiC coatings are known for their exceptional properties, including high temperature resistance, mechanical strength, and excellent corrosion resistance.

As a leading upstream graphite material manufacturer in the semiconductor industry, Semicorex prioritizes the availability, usability, and durability of its materials, setting the standard for excellence in the field.

In the front-end process (FEOL) of semiconductor manufacturing, the wafer needs to be subjected to various process treatments, especially the wafer needs to be heated to a certain temperature, and there are strict requirements, because the uniformity of temperature has a very important impact on the product yield; at the same time, semiconductor equipment needs to work in the presence of vacuum, plasma and chemical gases, which requires the use of ceramic heaters.
