Substrate for carrying a semiconductor chip and semiconductor device using same

摘要

The objective of this invention is to provide a type of substrate for carrying a semiconductor chip that can increase the arrangement density of lands, and a type of semiconductor device that makes use of said substrate for carrying a semiconductor chip. Constitution: The conductor pattern on insulating substrate 102 contains lands 130 that are respectively connected to electrode pads 120 of semiconductor chip 100 via conductor wires 110. Each land 130 of conductor pattern 110 as capillary tool contact portion 202 where the capillary tool makes contact during bonding, and wire contact portion 204 that allows contact of conductor wire 110. The portion of wire contact portion 204 on the side toward capillary tool contact portion 202 becomes constricted portion 200. Lands 130 are positioned such that constricted portion 200 and capillary tool contact portion 202 of adjacent lands 130 are arranged facing each other.
