Patent ID: 7637714

Claim:
A method for removing semiconductor chip in which one out of a plurality of semiconductor chips formed from a diced semiconductor wafer is removed from a pressure-sensitive adhesive sheet, which holds the semiconductor chips by adhering thereto, so that the semiconductor chip is extracted from the adhesive sheet, the method comprising: bringing a plurality of protruding portions on a first contact surface of a removing member into contact with a bottom surface of the semiconductor chip through the adhesive sheet at a region on a bottom surface side of the adhesive sheet while sucking and holding a vicinity of the bottom surface-side region of the adhesive sheet corresponding to an adhesion region of the semiconductor chip by a second contact surface of a holding portion located around the first contact surface; sucking the adhesive sheet in between the respective protruding portions so as to partially remove the adhesive sheet in the adhesion region from the semiconductor chip at suction positions; and moving respective contact positions with the protruding portions to the suction positions on the bottom surface-side region of the adhesive sheet by moving the removing member along the bottom surface of the semiconductor chip relative to the holding portion, in a condition in which the first contact surface is located at an almost same height of the second contact surface, so that a region of the partial removal in the adhesion region is made to expand.
