Title: Semiconductor pressure detector
Inventor: TAKEUCHI TAKANOBU
IPC: G01L9/04
Filed: 1990-12-19
Abstract: PURPOSE:To obtain a low-noise semiconductor pressure detection device which is immune to the effect of crystal defect on the surface. CONSTITUTION:A p type pressure sensing resistor 2 is formed on an n type substrate 1 while an n type reversal region 5, which is an opposite type to the pressure sensing resistor 2 is formed on the front side of the pressure sensing resistor 2. Since the reversal region 5 is installed on the surface of the pressure sensing resistor 2, the current flows only at a depth of the reversal region 5, but does not flow on the surface where there exist many crystal defects, which prevents the generation of fluctuations in the current. It is, therefore, possible to reduce the generation of noise induced by current fluctuations.
