Filed: 1998-12-30
Abstract: PURPOSE: A method for forming an isolation layer of a semiconductor device is provided to improve a production yield and an electric characteristic in a semiconductor element isolation process by compensating an etching damage generated when forming an isolation layer in a trench. CONSTITUTION: A pad oxide layer(102) and a nitride layer(104) are deposited on a semiconductor substrate(100). The substrate is patterned from the nitride layer by using a photoresist layer for an isolation mask, thereby forming a trench(106) in the substrate. The photoresist layer is removed, a first thin oxide layer(108) is formed in the trench at a temperature of beyond 1000deg.C at an atmospheric pressure. A second thin oxide layer(110) is formed at a temperature of 700-850deg.C at a low pressure of below 1Torr. A third oxide layer(112) for sufficiently filling the inside of the trench is formed at a temperature of 550-650deg.C at a high pressure of 1Torr over. The third oxide layer is polished until the nitride layer is exposed by an evenness process, thereby forming an isolation layer(ISO) made of first to third oxide layers buried in the trench. The nitride layer and the pad oxide layer are removed. Thereby, the method for forming an isolation layer of a semiconductor device compensates an etching damage generated when forming the isolation layer in the trench, and thus improves a production yield and an electric characteristic in a semiconductor element isolation process.

Abstract: PURPOSE: A device for lighting on a turn signal lamp of a vehicle is provided to prevent disorder of the fusion of a mobile contact point unit with a stopper member of a flash due to super heat by over-current by covering the stopper member of the flash unit with a heat resistant material. CONSTITUTION: A mobile contact point(104) contacts to a fixed contact point(103) periodically by the electromagnetic force generating from an electromagnet(102). DC voltage(B+) is fed to a turn signal lamp(40) periodically and the turn signal lamp is flickered. Due to inflow of rain water to the turn signal lamp, a short is occurred between a terminal L and a terminal E of a power supply terminal part(101), over-current flows in a circuit line from a battery to the terminal L. Due to the over-current, a fuse(10) is melted and cut-apart and the circuit between the power supply terminals is opened. The over-current is cut off. Super heat is generated due to the over-current in the circuit line while over-current flows before the fuse is melted and cut-apart. By the super heat, a stopper member(105) formed of a material which is weak to heat is fused. The stopper member is covered with a heat resistant cover member(110). Thereby, the stopper member doesn't directly contact to the mobile contact point and the stopper member is not fused with the mobile contact point.

The current mirror circuit(40) connects an output of the adder(30) to the cathode of the laser diode.
