Patent ID: 8499813

Claim:
A tool for separating a semiconductor die from at least one layer of a tape having first and second layers, the first and second layers held together with a peeling strength, the tool comprising: a plurality of ejector pins; a support table including an upper surface for supporting the tape and semiconductor die, the support table further including an aperture in the upper surface through which aperture the plurality of ejector pins extend, the aperture having at least one chamfered sidewall, the at least one chamfered sidewall provided so that a distance between the at least one chamfered sidewall and a wall opposite the at least one chamfered sidewall is greater at the upper surface of the support table as compared to a same dimension at a lower surface of the support table opposite the upper surface; and a vacuum source for holding the first layer of the tape to the support table, the vacuum source being communicated to the aperture and exerting a force on the first layer of the tape exceeding the peeling strength.
