Abstract:
A semiconductor device comprising:a semiconductor chip;a mold portion for encapsulating said semiconductor chip; andinner leads extending substantially parallel to a circuit formation surface of said semiconductor chip in said mold portion and protruding outward from side surfaces of said mold portion,wherein said mold portion comprises an upper-mold portion covering the circuit formation surface of said semiconductor chip and a lower-mold portion covering an opposite surface of said semiconductor chip, and a width of said upper-mold portion is smaller than a width in the same direction of said lower-mold portion and said upper and lower-mold portions are disposed so that an end face of said upper-mold portion is offset by a distance greater than 0 .mu.m and not greater than 50 .mu.m from an end face of said lower-mold portion on at least one side surface of said mold portion, establishing a positional deviation between the end face of the upper mold and the end face of the lower mold.
