Title: Manufacture of pressure sensor
Inventor: SUZUKI KENICHIRO
IPC: H01L29/84
Filed: 1985-09-25
Abstract: PURPOSE:To prevent fluctuation of the sensitivity by providing in part of the protective film a window region for detection which is smaller than the window region for forming a diaphragm, and detecting the change in the etching shape of the window region for detection. CONSTITUTION:A window region 43 for a diaphragm and a window region 20 for detection are formed closely to each other in a protective film 41 using a photolithography technique. In these window regions 43, 20, the protective film 41 is removed to expose the underlying silicon substrate 40. As the etching proceeds, the size of the bottom surface 23 of an etching hole 22 for detection decreases and soon exhibits the shape of a pointed head. At this moment the operator lifts up the sample from the etchant and stops the etching. The hole 22 for detection is observed in such ways as follows. (1) A television camera is placed beside the etching apparatus, and the image displayed on the television screen is monitored. (2) The sample is lifted up from the etchant just before the etching is completed, and is observed with a microscope. At this time, if the etching is not sufficient, the sample is again dipped in the etchant. (3) Observation is made from a side of the etching apparatus using a loupe.
