SEMICONDUCTOR DEVICE AND SEMICONDUCTOR DEVICE MANUFACTURING METHOD

摘要

A semiconductor device manufacturing method comprising the steps of preparing a first substrate (10) including an integrated circuit chip (12), a first connection terminal electrically connected to a terminal of the integrated circuit chip, and a first connection portion (16a, 17a) spaced from the first connection terminal, preparing a second substrate (20) including a second connection terminal electrically connected to the first connection terminal and a second connection portion (23a, 24a) spaced from the second connection terminal, providing a connecting metallic material portion (30) on the first or second connection portion, and interconnecting the first and second connection portion through the metallic material portion by thermocompression bonding to fabricate a laminate of the first and second substrates.
