Изотропное травление и анизотропное травление кремниевой пластины

PAM-XIAMEN can provide etching silicon wafer in P type and N type, more specifications please see: https://www.powerwaywafer.com/silicon-wafer/etching-wafer.html. The etching of silicon wafers is divided into isotropy and anisotropy, shown as Fig. 1. Isotropy etching means that the etching rate of silicon in all directions is the same during the etching process, and the etching result is [...]

Почему кремниевая пластина является наиболее подходящим материалом для изготовления чипов?

When it comes to choosing a material as the basic material for transistors in computers, the key matter we need to consider is resistance. Conductors have very low resistance and can conduct electricity easily; insulators have high resistance and cannot conduct electricity. For transistors, it is necessary to be [...]

Кое-что о внутренних и внешних полупроводниках

There are three basic types of semiconductor materials: intrinsic semiconductors, extrinsic semiconductors, also known as impurity semiconductors. Both types of semiconductor materials can be supplied by PAM-XIAMEN. 1. What Is Intrinsic Semiconductor? Intrinsic semiconductor refers to a pure semiconductor that is completely free of impurities and lattice defects, and generally such [...]

Кремниевая вакансия (Vsi) — центр спинового окрашивания в карбиде кремния

Solid-state spin color center is an important research platform for quantum information processing, and diamond nitrogen vacancy (NV) color center is its outstanding representative. Since the detection of a single diamond NV color center at room temperature was reported by a German research team in 1997, important progress has [...]
