  • Patent number: 7353719
    Abstract: A pressure sensor comprising a plurality of sensor parts arranged in matrix. A first electrode being connected with first wiring and a second electrode being connected with second wiring are disposed oppositely through a cavity part in the sensor part. The second electrode bends to the first electrode side in response to a pressure from a specimen and touches the first electrode upon application of a pressure of a specified level or above. When the specimen is pressed against a pressure detecting region, both electrodes touch each other at a sensor part corresponding to a protrusion of the specimen and are separated at a sensor part corresponding to a recess. When a scanning signal is fed from a scanning circuit to one wiring and presence of a signal flowing through the second wiring is detected by a sensing circuit, a pressure being applied to each sensor part can be detected.

  • Patent number: 5411911
    Abstract: A process for producing a semiconductor device comprises the following steps 1 to 9. In step 1, a field oxide layer is formed on a first conductivity type semiconductor substrate to define an active region. In step 2, gate electrodes, second conductivity type source regions and drain regions are formed on the active region, word line are formed on the field oxide layer, and an insulating layer is formed over the substrate. In step 3, contact holes are formed through the insulating layer so as to partly expose the source regions. In step 4, a polysilicon layer is formed over the exposed source region and the entire surface of the insulating layer. In step 5, a photoresist pattern is formed on the polysilicon layer. In step 6, the polysilicon layer is etched under etching conditions where selectivity to the insulating layer is high using the photoresist pattern as an etching mask to simultaneously form a storage pattern and trenches in the semiconductor substrate at the source regions.
