Abstract

A tape carrier type semiconductor device comprising: a long flexible insulating tape; and a plurality of semiconductor devices sequentially arranged on one surface of the tape, wherein each semiconductor device has a wiring pattern and a semiconductor element, and wherein each semiconductor device has either a hole or a target mark inside a predetermined region enclosed by an outline of the semiconductor device, the outline being for die-cutting into pieces, the hole being bored through the tape for indicating that the semiconductor device is a non-defective, the target mark not being bored through the tape for indicating that the semiconductor device is a defective.

Claims (5)

1. A method of producing a tape carrier type semiconductor device, comprising the steps of:

arranging a plurality of semiconductor devices sequentially on one surface of a long flexible insulating tape;

forming either a hole or a target mark inside a predetermined region enclosed by an outline of each semiconductor device, the outline being for die-cutting into pieces, the hole being bored through the tape for indicating that the semiconductor device is non-defective, the target mark not being bored through the tape for indicating that the semiconductor device is defective; and

conducting a test using a tester to determine sequentially whether each of the plurality of semiconductor devices arranged on the surface is a non-defective or a defective.

2. The method of claim 1 , further comprising the step of die-cutting the plurality of semiconductor devices sequentially into pieces.
