Silicon etching
Introducing Photo Precision Co., Ltd., which contributes to prototyping and development in various fields, including microelectronics and optical products, with photofabrication as its core technology. "Silicon Etching" Overview A technology that etches the silicon substrate itself to form three-dimensional structures. ■□■ Features ■□■ ■ Utilizing the crystal orientation of silicon, it enables groove processing with flat groove walls (anisotropic etching). V-shaped and rectangular grooves can be formed. ■ Depending on the type of etching solution, rounded edges can be created on the groove walls, allowing for isotropic etching as well. ■□■ Types of Processing ■□■ ■ V-Groove Processing - Using silicon material with a <100> surface orientation, V-shaped grooves are formed. - The angle of the slope is always the same (54.7°). ■ Rectangular Groove Processing - Using silicon material with a <110> surface orientation, rectangular grooves are formed. - Due to the crystal structure, the direction of the grooves tilts at 54.7° relative to the side surface. ■ Isotropic - Etching progresses uniformly in all directions.
