Monolithic nozzle assembly formed with mono-crystalline silicon wafer and method for manufacturing the same

摘要

A monolithic nozzle assembly for fluid, and a method for manufacturing the same with a single mono-crystalline silicon wafer by continuous self-alignment are provided. The monolithic nozzle assembly can be formed with a single (100) monocrystalline silicon wafer. Compared with a complicated nozzle assembly formed using a great number of silicon wafers and plates, the configuration of the monolithic nozzle assembly is simple, and can be manufactured on a mass production scale by semiconductor manufacturing processes. The monolithic nozzle assembly can be manufactured by continuous self-alignment, including anisotropic etching using the characteristic of the crystal plane of silicon, and LOCOS-based masking. Compared with a common photolithography process, the alignment error may be reduced below a few microns. The overall manufacturing process is simple and efficient with a high yield.
