Processing Materials

The machining of semiconductor components relies on a variety of high-purity, high-performance materials, and the characteristics of these materials directly impact the performance, efficiency, and reliability of semiconductor devices. From traditional silicon materials to advanced compound semiconductor materials, each type of material has its own unique physical and chemical properties as well as specific application scenarios. Selecting the appropriate material is a critical first step in semiconductor component machining. We shall make precise choices from among various materials based on different application requirements. Below are some of the commonly used materials in our semiconductor component machining processes:

Aluminum Alloy

Aluminum alloy is a material composed primarily of aluminum, with the addition of specific amounts of other alloying elements such as copper, manganese, silicon, magnesium, zinc, and others. With the incorporation of these alloying elements, aluminum alloys retain the fundamental characteristics of aluminum, such as low weight and excellent electrical and thermal conductivity, while also gaining higher strength, improved castability and workability, and outstanding corrosion resistance

Red Copper

Red copper refers to high-purity copper materials, named for their distinctive reddish color, and is also commonly called pure copper. Red copper possesses extremely high purity, with a typical copper content above 99.5% and minimal impurities. It offers exceptional electrical and thermal conductivity.

Silicon Nitride Ceramic

Silicon nitride is an inorganic compound with the chemical formula Si₃N₄. It is an important structural ceramic material known for its high hardness, inherent lubricity, and excellent wear resistance, being an atomic crystal; it also exhibits oxidation resistance at elevated temperatures. In addition, silicon nitride can withstand thermal shock; even when heated in air to above 1000°C and then subjected to rapid cooling followed by rapid reheating, it will not fracture.

Polytetrafluoroethylene (PTFE)

Polytetrafluoroethylene, abbreviated as PTFE and also known by the trade name Teflon or commonly referred to as the “King of Plastics,” is a high-molecular-weight polymer produced by the polymerization of tetrafluoroethylene monomers, with the chemical formula (C₂F₄)ₙ. It exhibits excellent resistance to heat and cold, and can be used continuously at temperatures ranging from -180°C to 260°C. This material is resistant to acids and alkalis, as well as to a wide range of organic solvents, and is virtually insoluble in all solvents.
