Abstract: PURPOSE:To prevent the generation of damage induced by the leakage of polysilicon due to a defective edge in an U-shaped groove by forming a second isolation section which intersects with a first isolation section between outside bases in a transistor region. CONSTITUTION:Two transistor regions which comprise a collector section 3, and an emitter section 4, which are isolated by an insulation film section 6 and an outer base section 5, are isolated by a U-shaped isolation section 2 and thus formed. A U-shaped groove section 2a, which further extends the U-shaped groove section, is installed between outside base sections 5. The formation of the U-shaped groove described above calls for the application of a mask capable of connecting the U-shaped isolation section 2a with the U-shaped isolate section 2. This construction makes it possible to prevent the generation of damage induced by the leakage of polysilicon due to a defective edge in the U-shaped groove.

Title: Semiconductor device
Inventor: SAKURAI NAOKI
IPC: H01L21/336
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To expand the reverse-bias safe operating region (RBSOA) of an insulated gate bipolar transistor by providing a second n<-> -layer, whose impurity concentration is lower than an n-layer and higher than the first n<-> -layer, between the n-layer and the first n<-> -layer. SOLUTION: An n-layer 2 is formed on a substrate 1. An n<-> -layer 3, whose impurity concentration is lower than the layer 2, is formed on the layer 2. Furthermore, an n<-> -layer 4, whose impurity concentration is lower than the n<-> -layer 3, is formed on the layer 3. The resistivities and the thicknesses of the n<-> -layers 3 and 4 are selected, so that a depletion layer does not reach the n-layer when a power supply voltage is applied across an emitter and a collector. At the time of turn-off, the depletion layer extends in the n<-> -layer 4 having low impurity concentration. Therefore, the electric field is relaxed, and RBSOA expands. The n<-> -layer has the low impurity concentration and a long life time in comparison with the n-layer 2. Therefore, carrier does not dissipate rapidly. Since the current changing rate is small, the bouncing voltage is small.

Title: Adaptive line insertion device
Inventor: OUCHI TOKUHITO
IPC: G09G5/00
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To reduce distortion owing to the difference of resolution in the boundary of moving areas and to reduce the deterioration of the sharpness of an image by controlling the characteristic of an inter-line insertion means in accordance with a motion index at the time of inserting the line through the use of the inter-field line insertion means. SOLUTION: When a TV signal (a) is supplied from outside, a movement detection part 2 obtains a difference between the TV signal delayed by a one frame delay circuit 1 and the signal (a) which is not delayed, and generates the movement detection signal MD of three bits from the difference. When the detection signal MD is 1-6, a line insertion switch part 8 selects the outputs of the inter-field line insertion parts 7b-7g. When the detection signal MD sequentially increases from '1' to '6', the switch part 8 sequentially selects the insertion parts 7b-7g in accordance with the value of the detection signal MD and inserts the inter-field line by sequentially using the filter of a narrow pass band. Thus, resolution can be changed stepwise by gradually changing the pass band of the filter.
