Silicon Wafer
PAM-XIAMEN, a silicon wafer manufacturing company, offers silicon wafer: FZ Silicon wafer, Test Wafer Monitor Wafer Dummy Wafer, Test Wafer,CZ wafer, epitaxial wafer, polished wafer, etching wafer.
The silicon wafer manufacturing process is crystal pulling, silicon wafer dicing, silicon wafer grinding, chamfering, etching, polishing, cleaning and inspection, among which crystal pulling, silicon wafer polishing and inspection are the core links of silicon wafer manufacturing. As the basic semiconductor substrate, silicon wafers must have high standards of purity, surface flatness, cleanliness, and impurity contamination to maintain the original designed functions of the chip. The high-specification requirements of semiconductor silicon wafers make its manufacturing process complicated. The four core steps include polysilicon purification and polysilicon ingot casting, single crystal silicon wafer growth, and silicon wafer cutting and shaping. As a raw material for wafer fab, the quality of silicon wafers directly determines the stability of the silicon wafer application process. Large-size silicon wafers have become the future development trend of silicon wafers. In order to improve production efficiency and reduce costs, more and more large-size silicon wafers are used.

12 "wafers de silício 300 milímetros TOX (Si térmica Oxidação Wafer)
PAM-XIAMEN offers 300mm silicon oxide wafer and dioxide wafer. Thermal oxide silicon wafer or silicon dioxide wafer is a bare silicon wafer with oxide layer grown by dry or wet oxidation process. The thermal oxide layer of the silicon wafer is usually grown in a horizontal tube furnace, and the silicon wafer oxide temperature range is generally 900 ℃ ~ 1200 ℃. Compared with CVD oxide layer, silicon wafer oxide layer has higher uniformity, better compactness, higher dielectric strength and better quality.

Flutuar-Zone Mono-Crystalline Silicon
A PAM-XIAMEN pode oferecer wafer de silício de zona flutuante, que é obtido pelo método Float Zone. As hastes de silício monocristalino são obtidas através do crescimento da zona flutuante e, em seguida, processam as hastes de silício monocristalino em pastilhas de silício, chamadas pastilhas de silício da zona flutuante. Uma vez que a pastilha de silício fundida por zona não está em contato com o cadinho de quartzo durante o processo de silício por zona flutuante, o material de silício está em estado suspenso. Assim, é menos poluído durante o processo de fusão da zona flutuante de silício. O teor de carbono e o teor de oxigênio são menores, as impurezas são menores e a resistividade é maior. É adequado para a fabricação de dispositivos de energia e certos dispositivos eletrônicos de alta tensão.

Cz Mono-Crystalline Silicon
PAM-XIAMEN, a monocrystalline bulk silicon producer, can offer <100>, <110> and <111> monocrystalline silicon wafers with N&P dopant in 76.2~200 mm, which are grown by CZ method. The Czochralski method is a crystal growth method, referred to as the CZ method. It is integrated in a straight-tube heat system, heated by graphite resistance, melts the polysilicon contained in a high-purity quartz crucible, and then inserts the seed crystal into the surface of the melt for welding. After that, the rotating seed crystal is lowered and melted. The body is infiltrated and touched, gradually raised, and finished or pulled through the steps of necking, necking, shouldering, equal diameter control, and finishing.

Epitaxial Silicon Wafer
Silicon Epitaxial Wafer(Epi Wafer) is a layer of epitaxial silicon single crystal deposited onto a single crystal silicon wafer(note: it is available to grow a layer of poly crystalline Silicon layer on top of a highly doped Singly crystalline silicon wafer, but it needs buffer layer (such as oxide or poly-Si) in between the bulk Si substrate and the top epitaxial silicon layer. It also can be used for thin film transistor.
