Abstract
PURPOSE: To provide a given resistance at a high accuracy preventing horizontal diffusion by utilizing a reverse conductivity type impurity region provided at the portion projected from one surface of a single conductivity type semiconductor substrate.
CONSTITUTION: A projection 13 is provided on the main surface of a semiconductor substrate 12 with a folded plane. A reverse conductivity type region is formed thereon not deeper than reaching the bottom from the top. This region serves as a resistance element whose surface is covered with an oxide film 15. After the formation of the projection, reverse conductivity impurity is introduced thereto. This prevents horizontal difusion thereof thereby specifying the cross-sectional shape of the region 14. Thus, a given resistance can be obtained. In addition, narrowing the space between lines, namely, the space between sides 14 and 14 of the resistance is possible thereby enabling higher integration.
