A method for producing a semiconductor device includes: a) an attaching process in which a flat-plate member is positioned on a flat-shape lead frame provided with a plurality of leads and a plurality of support bars so that the flat-plate member contacts at least the plurality of leads, and the flat-plate member is attached to plurality of support bars; b) an element mounting process in which a semiconductor element is mounted on the flat-plate member attached to the plurality of support bars of the flat-shape lead frame; c) a wire-bonding process in which a wire is provided between each of the plurality of leads and the semiconductor element; and d) a separating process, performed after the completion of the wire-bonding process, in which the plurality of support bars are deformed so as to separate the flat-plate member and the plurality of leads and electrically disconnect or separate the flat-plate member from the plurality of leads.

Semiconductor device and method for producing a semiconductor device

There is provided a mounting construction which prevents leads of a semiconductor device from being short circuited when the semiconductor device is mounted on a mounting board so that mountability of the semiconductor device is improved. A plurality of outer leads extend from sides of a package of the semiconductor device. A mounting board has a surface on which a plurality of terminals to be electrically connected to the semiconductor device are provided. A mounting member is mounted on the mounting board separately from the semiconductor device. The semiconductor device is attached to the mounting member. The mounting member has a frame member forming a space in which the semiconductor device is placed. A first connecting lead has a first lead connecting portion and a first external connecting portion to be connected to a one of terminals provided on the mounting board. The first external connecting portion extends along a bottom surface of the frame member. A second connecting lead has a second lead connecting portion and a second external connecting portion to be connected to a one of the terminals provided on the mounting board. The second external connecting portion extends along a bottom surface of the frame member. The first external connecting portion and the second external connecting portion are arranged alternately with a predetermined distance apart from each other in a direction along an extending direction of the frame member.
