Abstract:
1. A semiconductor sensor comprising: a body including a hollow tube portion and a bottom portion for covering an opening of the tube portion, the bottom portion being thinned to a predetermined thickness that allows the bottom portion to be deformed according to pressured applied thereto; an insulating layer; and a semiconductor layer disposed on the insulating layer, the semiconductor layer having at least one gauge section including a sensing portion configured to be deformed according to an amount of physical quantity applied thereto, the gauge section further including first and second bonding pads respectively connected to different positions of the sensing portion, wherein the gauge section is mounted to only the bottom portion of the body, and wherein an electrical resistance between the first and second bonding pads changes with a change in the amount of the applied physical quantity.
