Abstract
In a semiconductor device manufacturing process, a semiconductor wafer is diced into a plurality of semiconductor chips, which are then peeled, from a dicing tape, using a peeling device. The peeling device includes a plurality of annular contact members arranged one after another from the outside to the inside, and the annular contact members are operated so that the semiconductor chip is successively peeled from the tape from the outer circumferential portion thereof toward the central portion thereof.
Claims2
A method of peeling a semiconductor chip, comprising the steps of:
- peeling a semiconductor chip adhered to a tape from said tape by a peeling device including a plurality of displaceable contact members arranged in an order from an outer circumferential position to a central position all being housed inside a stationary contact member,
- wherein the plurality of displaceable contact members are operated and displaced relative to each other so that the semiconductor chip is successively peeled off from the tape from the outer circumferential position thereof toward the central position, wherein the plurality of displaceable contact members are simultaneously moved, and then, an outermost displaceable contact member in the plurality of displaceable contact members is stopped and the remaining displaceable contact members are further moved simultaneously.
