Abstract: PURPOSE:To suppress charge-up and heat build-up of a mask material and enable ion to be impregnated highly accurately into a desired region by performing ion implantation of impurities into the surface of a semiconductor substrate with the double-layer structure of a conductive thin film and a mask material as a mask. CONSTITUTION:A conductive thin film 8 is formed on the entire surface of a semiconductor substrate 1 and a mask material 7 on ion implantation is formed on the entire surface of the conductive thin film 8 to perform patterning of the mask material 7 to a desired pattern. Then, the conductive thin film 8 is selectively etched using a desired pattern of the mask material 7 and impurities are subject to ion implantation to the semiconductor substrate with the double-layer structure of the conductive thin film 8 and the mask material 7 formed by selective etching as a mask. The conductive thin film 8 allows heat generated within ion implantation to escape to the periphery part of the wafer, prevents the pattern of the mask material 7 from deteriorating, and achieves ion implantation highly accurately.

Title: Air-fuel ratio controller of internal combustion engine
Inventor: NISHIDE HIROTO
IPC: F02P5/152
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To prevent knocking during lean running in which an air-fuel ratio is controlled in an open manner by detecting knocking with a knocking detecting means and switching from the lean running to a stoichi running with knocking time air-fuel ratio control switching means during the detection of the knocking. SOLUTION: When the generation of knocking is detected by a knocking detecting means 106 during lean running in which an air-fuel ratio is open- controlled to a lean side based on an air-fuel learning value, running is switched to stoichi running in which an air-fuel ratio is temporarily feedback-controlled to a logical air-fuel ratio by a knocking time air-fuel control switching means 107. Then, a fuel injection amount from a fuel injection valve 100 is calculated by a means 102 based on an air-fuel ratio feedback correction factor and the air-fuel ratio learning value so as to bring the air-fuel ratio close to the logical air-fuel ratio during the stoichi running. The air-fuel ratio learning value is renewed by a renewing means 104 based on the air-fuel ratio feedback correction factor. Thus, the generation of knocking is limited.
