Why is chlorine generally added in the thermal oxidation process?

What is the thermal oxidation process? The thermal oxidation process is used in semiconductor manufacturing to generate a silicon dioxide (SiO₂) layer on the surface of wafers. It is divided into wet oxidation and dry oxidation, and is mainly used in chip fabrication to create insulating layers such as gate oxide layers, field oxide layers, STI isolation layers, or protective passivation layers.

Factors Affecting the Durability of Carbide Drill Bits

There are six factors that affect the durability of hard alloy drill bits during drilling operations. The first factor is whether the clamping method of the hollow hard alloy drill bit is correct. The second factor affecting durability is the concentricity of the drill machine's drive shaft. The third factor is whether the gap between the large gear and the small gear of the drill machine is small.
