Abstract
Disclosed are an apparatus and a method for separating a semiconductor chip disposed on a base member via an adhesive member from the base member. The method includes: a step of providing a push member on a side of the base member opposite to a side on which the semiconductor chip is disposed and moving the push member in a direction towards the semiconductor chip; and a step of separating the semiconductor chip, moved together with the push member, from the base member through a pick-up unit. The adhesive member and the push member are each magnetized such that repulsive forces act on each other.
