Grabado isotrópico y grabado anisotrópico de oblea de silicio

PAM-XIAMEN can provide etching silicon wafer in P type and N type, more specifications please see: 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 [...]

¿Cómo limpiar las obleas de silicio (Si)?

As the basis for making photovoltaic cells and integrated circuits, silicon wafer cleaning is very important. The effect of cleaning directly affects the final performance, efficiency and stability of photovoltaic cells and integrated circuits. Cleaning the silicon wafer not only removes impurities on the surface of the silicon wafer [...]

Algo sobre semiconductores intrínsecos y extrínsecos

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 [...]

Silicon Vacancy (Vsi) — Spin Color Center en carburo de silicio

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 [...]

¿Por qué se requiere el adelgazamiento de obleas?

From the perspective of the cross-sectional structure of integrated circuits, most integrated circuits are fabricated on the shallow surface layer of the silicon base material. Due to the requirements of the manufacturing process, high requirements are placed on the dimensional accuracy, geometric accuracy, surface cleanliness and surface micro lattice [...]

¿Qué es el chaflán en la oblea semiconductora?

Chamfer is to grind away the sharp edges and corners around the wafer. Its purpose is to make the mechanical strength of the wafer bigger prevent the wafer edge from cracking, to prevent damage caused by thermal stress, and to increase the flatness of the epitaxial layer and the [...]
