Film carrier tape and laminated multi-chip semiconductor device incorporating the same and method thereof

摘要

A film carrier tape and laminated multi-chip semiconductor device incorporating the same and method thereof wherein a plurality of chip semiconductor devices are laminated onto a substrate. Each chip semiconductor device includes a film carrier tape having leads, a semiconductor chip electrically connected to the leads, a heat sink mounted to a surface of the chip, and a connector for mounting the heat sink, the connector being electrically connected to the leads of the film carrier tape. The film carrier tape includes a carrier member having a metallic layer superposed thereon which is etched so as to form the leads and the heat sink.
