Tab-type semiconductor process

摘要

A TAB (Tape Automated Bonding) process uses single-layer tapes to form a semiconductor structure. Beam leads on a metal tape are "inner-lead bonded" to a chip. Each chip site on a specially-formed plastic tape has a central portion and a peripheral portion which are bonded to the chip so that the central portion forms a protective cover over the chip and the peripheral portion acts as a support for the beam leads during probe testing, excising and forming operations, etc. The bottom surface of the chip preferably remains uncovered so that it can, if appropriate, be electrically connected to ground or another potential.
