Abstract:
A method for fabricating semiconductor devices having a semiconductor chip having an internal terminal arranged in a center part of a surface thereof, an external terminal arranged around peripheries of the semiconductor chip, and a TAB lead consisting of an inner lead and an outer lead, the inner lead connecting to the internal terminal and the outer lead connecting to the external terminal, the TAB lead adhering to a TAB tape laid on the surface of the semiconductor chip, the TAB tape having a device hole in a center part thereof and a periphery parallel to a periphery of the semiconductor chip, the method comprising the steps of:fixing the TAB tape to a surface of the semiconductor chip by thermo-compression bonding so that the inner lead extends over the internal terminal arranged in the center part of the surface of the semiconductor chip and exposed in the device hole, and the outer lead across a slit of the TAB tape extends outward beyond a periphery of the semiconductor chip;connecting the inner lead to the internal terminal by thermo-compression bonding;separating the TAB lead for the semiconductor chip by cutting the outer lead in the slit of the TAB tape and a part of the TAB tape supporting the TAB lead to be separated so that the outer lead extends outward beyond a periphery of the semiconductor chip; andconnecting the outer lead to the external terminal by thermo-compression bonding.
