Patent ID: 6916686

Claim:
A method of manufacturing a semiconductor device, comprising the steps of: (a) inspecting a plurality of semiconductor chips on a semiconductor wafer thereby sorting out defectives from conforming ones thereof; (b) separating the plurality of semiconductor chips into pieces by dicing the semiconductor wafer with the top surface thereof, partitioned into a plurality of semiconductor chip-forming regions; (c) preparing a contact collect with a suction head coming in contact with the top surface of the respective semiconductor chips, smaller in surface area than the respective semiconductor chips, and sucking and securely holding the respective semiconductor chips separated into pieces with the contact collect by abutting the suction head of the contact collect against the top surface of the respective semiconductor chips separated into pieces; (d) executing die bonding of the respective semiconductor chips over a top surface of a mounting base by pressing the back surface of the respective semiconductor chips sucked and securely held by the contact collect against the top surface of the mounting base; and (e) connecting bonding pads formed over the top surface of the respective semiconductor chips to conductor layers formed over the top surface of the mounting base via a wire, respectively, wherein a protection layer for preventing direct contact of the suction head of the contact collect with the top surface of the respective semiconductor chips is provided over the top surface of the respective semiconductor chips prior to sucking and securely holding the respective semiconductor chips with the contact collect, and wherein only the semiconductor chips that are determined as the conforming ones at inspection are provided with the protection layer.
