Title: Manufacture of micropump
Inventor: KAMISUKE SHINICHI
IPC: F04B43/02
Filed: 1990-02-08
Abstract: PURPOSE:To improve a seal quality in a valve part of a micropump by integrally molding a thin film plate by wet type anisotropic etching with a (100) surface direction silicon wafer and forming an energizing film only in a valve part. CONSTITUTION:Both surfaces of a wafer of surface direction (100) are ground to form a board 1, oxidized film 2 over a total surface and an etching mask pattern 3. Next a non-through hole 4 is formed by etching, and a through hole 4a is formed by forming a diaphragm 6 and a valve film of a valve 5 by the second time etching. Next an energizing film 7 is formed by mask spattering, and a film plate 8 for a pump main unit is obtained by performing thermal oxidation. A micropump is formed by sandwiching the thin film plate 8 by glass boards. A seal quality is improved by giving a preload to the valve film by the thickness of the energizing film without fusing the glass plate and the thin film plate by the oxidized film.
