IPC: H01G11/22
Filed: 1988-08-22
Abstract: PURPOSE:To improve an electrical conductivity and a specific surface area by employing activated vapor growth carbon fiber as polarizing electrode material. CONSTITUTION:Vapor growth carbon fiber(VGCF) which is subjected to a thermal treatment under the existence of H2O and CO2 to increase its specific surface area, i.e., so called activated VGCF, is employed as polarizing electrode material. That is, the growth process of VGCF is such that the fiber is extended along the axial direction with an extra-fine particle of iron compound or the like as a growth nucleus while thermally decomposed carbon is deposited around it. However, its specific surface area is as small as about 10-25m<2>/g as it is and activation treatment is necessary.

Title: Manufacture of semiconductor pressure sensor
Inventor: NISHIDA YASUAKI
IPC: H01L29/84
Filed: 1989-08-11
Abstract: PURPOSE:To enable accurate detection of a pressure without use of a pedestal by fluidizing a resin almost radially outward from the center of a carrying position with respect to a carrying surface of a semiconductor pressure sensing element. CONSTITUTION:In the molding of a resin package, a pin gate 3 is provided to inject a resin vertical to a silicon pellet carrying surface 1 and toward the center of position 2 of carrying silicon pellet indicated by the broken line. As a result, the resin is fluidized radially outward from the center of the carrying position 2 as indicated by the arrow. When a resin package 4 undergoes a temperature change, a thermal stress is generated parallel with the carrying surface 1 and outward isotropically way on the center of the carrying position 2. Thus, as the thermal stress is applied to a silicon pellet 5 fastened direct on the resin package 4 isotropically way outward on the center of the silicon pellet, there is no distortion caused by the thermal stress in a diaphragm section of the silicon pellet 5. In other words, this eliminates an undesired output otherwise caused by the thermal stress thereby enabling accurate detection of a pressure.
