Filed: 1982-03-08
Abstract: PURPOSE:To permit substantial reduction in the number of processes and to improve yield by a method wherein a wafer having a P-N junction is subjected to scribing with it being adhered onto a conductive adhesive sheet and in this state energizing inspection is carried out. CONSTITUTION:A semiconductor wafer having a P-N junction formed therein is adhered onto a conductive adhesive sheet. Next, the then wafer is half-cut or full-cut and, in this state, electric characteristics of the chip are inspected through a conductive adhesive agent. This inspection method permits even the chip full-cut at the time of cutting to be subjected to an energizing test in the state as it is. With this inspection method, it becomes possible to carry out the energizing inspection even in case that the wafer is full-cut into chips, thus permitting substantial reduction in the number of processes. It is also possible to prevent a phenomenon such as chip breakage which would be occurred when dividing the half-cut wafer thereafter, thus improving yield.
