Title: Manufacture of passivation film
Inventor: CHINO TOYOJI
IPC: H01L21/318
Filed: 1990-01-30
Abstract: PURPOSE:To obtain a passivation film made of an SiON film from SiH4 gas, N2O gas and NH3 gas and to obtain a device having small leakage current by performing its vapor growth. CONSTITUTION:The flow rate ratio of SiH4 gas, N2O gas, NH3 gas and N2 gas, pressure in a reaction furnace and a board temperature are controlled in an atmosphere in which these gas coexist, and the gases are decomposed by light emitting, and SiOH is vapor grown. An SiON film 6 is formed on the surface of a compound semiconductor. In this case, a stress generated in a boundary between the film 6 and the semiconductor by the influence of oxidizing and reducing reactions of a step of deposing the film 6 is reduced as compared with that when an Si3N4 film and an SiO2 film are formed. Thus, a leakage current to a bias voltage between a collector 1 and an emitter 3 of a leakage current of a phototransistor in which the film 6 is deposited can be suppressed to a low value.

Patent JP-H03225987-A (JP)
Title: Semiconductor laser
Inventor: NARUI HIRONOBU
IPC: H01S5/00
Filed: 1990-01-31
Abstract: PURPOSE:To effectively avoid that a leakage current is generated by a method wherein the band gap of a current-blocking layer of a first conductivity type and a second clad layer of a second conductivity type is made larger than the band gap of a clad layer of the first conductivity type and a first clad layer of the second conductivity type. CONSTITUTION:A second clad layer 7 [p2] of a second conductivity type, e.g. a p-type, and a current-blocking layer 6 [n2] of a first conductivity type, e.g. an n-type, form a p-n junction; a first clad layer 5 [p1] of the second conductivity type and a clad layer 3 [n1] of the first conductivity type form a p-n junction via an active layer 4. The band gap of the regions p2 and n2 is larger than the band gap of the regions p1 and n1. As a result, even when a bias voltage corresponding to about a builtin potential of the p-n junction between the regions p1 and n1 is applied to a semiconductor laser, an electric current hardly flows to the junction between the regions p2 and n2 because a built-in potential of the p-n junction between the regions p2 and n2 is higher. It is possible to avoid that a leakage current is generated.

Title: Layout of vdmos pattern
Inventor: KOYAKATA HITOSHI
IPC: H01L29/06
Filed: 1989-01-31
Abstract: PURPOSE:To enable an intense electric field to be hardly applied onto a gate oxide film at a turn-OFF time so as to improve a basic cell in dielectric breakdown strength by a method wherein basic cells are arranged in rows in such a manner that they are displaced by one half the length of a side of a basic cell. CONSTITUTION:Basic cells are arranged not in a simple checkered pattern but in rows being displaced by one half pitch to constitute a transistor of low ON-resistance. When the transistor is turned OFF and the potential difference between a drain and a source is made to increase, a depletion layer 1 spread inside a P<-> layer and an N<-> layer spreads gradually to grow finally to be a depletion layer 2. That is, an upper limit of the intensity of an electric field applied to a gate oxide film appears at g and h inside the depletion layer formed at an aggregate point of three basic cells. But, even if the potential difference between the drain and the source is made to increase further, the upper limit of the intensity of the electric field applied to the gate insulating film decreases, because the distance between (g) and (h) is short. By this setup, an intense electric field is prevented from being applied onto a gate oxide film when a transistor is turned OFF and the transistor can be improved in dielectric breakdown strength.

Filed: 1983-02-16
Abstract: PURPOSE:To provide a diesel exhaust purification device having a better regeneration efficiency by continuously removing soot contained in the burnt gas so that clean and high temperature gas is supplied to the high temperature resistant filter. CONSTITUTION:Carbon particles contained in the exhaust gas from an engine E pass through a thermal catalytic filter 1 having a relatively small clogging, and flow into a downstream filter 2 with carbon particles left behind which are large enough to be trapped by the thermal catalyst. The downstream filter 2 traps fine particles which have passed through the upstream thermal catalytic filter. When the downstream filter 2 is detected to be clogged, a burner 3 is ignited to reactivate the filter. The combustible gas generated by the burner contains soft carbon. The soft carbon and larger carbon particles which are trapped by the thermal catalytic filter 1 are first burnt, and then the fine particles are burnt in the downstream filter 2.
