substrate in semiconductor
Semiconductor substrate materials Germanium, Silicon and Gallium Arsenide, are the basis for building microelectronic devices, with Silicon being the most commonly used substrate due to its mature preparation process and wide range of applications.
Epitaxy refers to the growth of a new single crystal layer on a treated substrate, a process that enhances specific properties of the substrate, such as optimizing device characteristics by adjusting the resistivity of the epitaxial layer.
substrate in semiconductor
As the mainstream choice of semiconductor substrate, monocrystalline silicon, whose single-crystal wafers are grown by either the straight-drawing or floating-zone methods, has a high degree of crystalline integrity and uniformity, and is an indispensable material for large-scale integrated circuits, where surface quality and doping control are critical to the final chip functionality.
