Silicon etching
Introducing Photoprecision, a company that contributes to prototyping and development in various fields, including microelectronics and optics, with photofabrication as its core technology. "Silicon Etching" Overview A technology that corrodes the silicon substrate itself to form three-dimensional structures. ■□■ Features ■□■ ■ Utilizes the crystal orientation of silicon to achieve flat-walled grooves (anisotropic etching). Can form V-shaped and rectangular grooves. ■ 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 remains constant (54.7°). ■ Rectangular Groove Processing - Using silicon material with a <110> surface orientation, rectangular grooves are formed. - Due to the crystal structure, the orientation of the grooves tilts at 54.7° to the side. ■ Isotropic - Etching progresses uniformly in all directions. ■ For more details, please download the catalog or contact us.
