Abstract

PURPOSE: To improve the performance of transistors by ion-implanting boron difluoride into a silicon substrate through a thermal oxide film, and activating the ion implantation regions by heating them with light exposure, thereby forming P-type regions.
CONSTITUTION: With a resist pattern 6 and a field oxide film 2 as a mask, boron difluoride is selectively ion-implanted through a gate oxide film 5 into the substrate 1 surface in a region where an element is to be formed. After removing the pattern 6, the oxide film on the implantation regions 108, 109 is removed to expose the upper surface of the regions 108, 109. The regions 108, 109 are heated and activated by a lamp anneal method, thereby forming a shallow P+ type source region 8 and a P+ type drain region 9. Whereupon, the surface level due to fluorine ions greatly reduces, so that the surface leakage at the source-drain junction greatly reduces. With this, the improvement of the performance of transistors is accomplished.
