Inventor: HIRUMA TAKEYUKI
IPC: H01S5/00
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To simplify the manufacturing process by a means such that a part of a semiconductor laminate frequency forms an optical guide, a part of which forms a mixed crystal part of an intermediate compsn. by the mutual fusion of semiconductor films. SOLUTION: On the top face of a substrate 1 an n-type AlGaInP clad layer 22, active layer 23, p-type AlGaInP clad layer 24, etching stop layer 25 and p-type AlGaInP clad layer 42 are formed to constitute a semiconductor laminate film onto the surface of which a laser beam is irradiated to locally heat and melt the semiconductor laminate film, thereby cousing it to change into an intermediate compsn. to form a mixed crystal part 9. The active layer 23 of the semiconductor laminate film forms an optical guide, and the mixed crystal part 9 is formed across a part of the optical guide. By forming the mixed crystal part 9 the loss due to the light absorption is avoided to prolong the life of a semiconductor element. The mixed crystal part 9 can be formed with only the irradiation of a laser beam, and the manufacturing cost can be reduced.

Abstract: PURPOSE:To prevent the generation of the potential due to the distribution resistance by connecting cells arranged on the peripheral part of an operation part by one conductive type diffusion layer so that at least a part of a channel region may operate. CONSTITUTION:A plurality of cells are repeatedly provided by patterning not only inside an operation region of a chip but also along the periphery of the operation region. The region shown by an arrow A is the operation region and an emitter electrode 20 covers this operation region. An emitter peripheral electrode 27 is formed so as to continuously connect to this emitter electrode 20, further having a short circuit with a p<+> diffusion region 29 so as to attain an object of a field plate for securing pressure-tightness. Then, the holes entering the p<+> diffusion region under a gate peripheral electrode 25 are drawn out from the emitter electrode 20 covering the operation region together with from this emitter peripheral electrode 27. Consequently, a potential drop due to the distribution resistance inside the p<+> diffusion layer 29 is gone, further, the whole periphery of the operation region is connected with the same repeated pattern with the inside so that uniform operation is realized so as to improve the latch up.

Title: Ic conenction circuit
Inventor: SHIRAI TOSHIHITO
IPC: H03K19/0175
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To improve resistance against micro fluctuation owing to noise when the output level of a front stage IC becomes almost equal to the level judgment threshold of the next stage IC at the time of a fault by inserting a connection circuit between the front stage IC and the next stage IC and level-converting the output level of the front stage IC at the time of the fault so that it becomes a value outside the level judgment threshold of the next stage IC. SOLUTION: Relating to the IC 1, a power voltage level is set to be a logic value '1' at normal time and a ground level is set to be a logic value '0' so as to output it. The signal VI of the output level which is not the logic value '1' or '0' and the signal VI is overlapped with the threshold of the IC 2 at the time of the fault. The connection circuit 4 level-converts the signal VI from the IC 1 into the signal VO which is not overlapped with the threshold of the IC 2. Even if the signal VI contains the threshold of the IC 2 owing to the fault of the output part of the IC 1, the logic value judgment of the IC 2 does not fluctuate by the subtle fluctuation of the signal VI and therefore the resistance of noise or the like is improved.
