Abstract

PURPOSE: To execute an accurate and easy alignment operation at a high-density mounting operation and at a soldering operation by a structure wherein leads in one part or more of a surface-mounting type semiconductor device are extended to the lower part from the bottom of the semiconductor device.
CONSTITUTION: Leads 2 on side faces of a semiconductor device main body 1 are provided with a gull-wing shape, a J-shape or the like so as to comply with a surface mounting operation. Leads 3 in one part or more are at an angle of 0 to 20° to a vertical direction and are extended to the lower part from the bottom of the semiconductor device main body 1. While the leads 3 are being inserted into through holes 5, this main body is soldered and mounted on a board 4 in which the through holes 5 have been formed in positions relative to the leads 3; thereby, the leads 2, 3 are mounted surely without a dislocation. Since through holes are not required in parts corresponding to the lower part of the leads 2, a high-density mounting operation can be realized when an electric circuit is formed on the rear or in an inside layer of the board 4. Even when recessed holes 6 are formed instead of the through holes 5, the same effect can be obtained.
