Title: Semiconductor pressure transducer
Inventor: KATOU YUKIHIRO
IPC: G01L9/04
Filed: 1986-11-24
Abstract: PURPOSE:To fix a pedestal and to reduce the cost of a semiconductor pressure transducer by clamping and fixing the pedestal through a metallic collar and pressing it from below with an O ring. CONSTITUTION:The pedestal 2 is formed in a projection shape to weaken a stress from a pedestal fixation side to a sensor chip 3. Further, the collar 6 is pressed from the top surface of the bottom part 2A of the pedestal 2 and a clearance 7 is provided between the bottom part 2A and collar 6. Then a stress due to clamping is applied only to the bottom part 2A perpendicularly to eliminate a radial stress. Consequently, an external stress and a thermal stress applied to the chip 3 are reduced in combination with the projection structure. Further, the squeezing margin of the O ring 4 can be prescribed by the size and shape of the collar 6, and sealing performance by the ring 4 is obtained. Further, when a clamping part 1c is clamped, no impact force is applied to the pedestal 2, which is prevented from breaking. The pedestal 2 is therefore fixed and the cost in mass-production is reducible.
