IPC: H01L21/316
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of element characteristics of a semiconductor device, by forming a film for forming a channel stopper which is wider than a film for anti-oxide film etching on the film for the anti-oxide film etching, and implanting impurity ions of one conductivity type into a semiconductor with the film for forming a channel stopper as a mask. SOLUTION: On an oxide film 2, a nitride film 3 having an anti-oxidizing property, an oxide film 10, a nitride film 11, and a polysilicon film 12 including phosphorus are deposited in this order. Nextly, part of the polysilicon film 12 and of the nitride film 11 within a LOCOS oxide film formation region are removed by etching. Then, with the oxidized polysilicon film 12 as a mask, P-type impurity ions for forming a channel stopper region are implanted into a semiconductor substrate 1 through the oxide film 10, the nitride film 3, and the oxide film 2. After that, the oxidized polysilicon film 12 is removed by etching and the oxide film 10 is patterned with the nitride film 11 as a mask and then the nitride film 3 is removed by etching with the oxide film 10 as a mask and thus a LOCOS oxide film is formed in the surface of the semiconductor substrate 1.

Title: Discharge lamp lighting circuit
Inventor: KIDO HIROSHI
IPC: H05B41/24
Filed: 1993-04-23
Abstract: PURPOSE:To improve circuit efficiency. CONSTITUTION:The voltage of a DC power source, which is obtained by rectifying AC power supply AC with a diode bridge DB, is boosted by a step-up circuit 1. An inverter circuit 2, which has a series resonance circuit composed of an inductor L1 and a capacitor C1, converts the DC power supplied from the step-up circuit 1d, into high-frequency power. A step-down transformer T connected in parallel to the capacitor C1 of the above series resonance circuit lower the voltage at both ends of the capacitor C1. The secondary output of this step-down transformer T lights a discharge lamp La. It become possible to use the step- down transformer as a transformer T to perform insulation from the side of the discharge lamp La by operating the inverter circuit 2, using the step-up voltage as a power source with the step-up circuit. Hereby, the oscillation current flowing to the series resonance circuit of the inverter circuit 2 is reduced to improve the circuit efficiency.
