Abstract:
1. A method of manufacturing a semiconductor device, comprising the steps of: forming an outside layer portion on a first surface of a semiconductor substrate comprising a plurality of semiconductor chips; forming a bump on the outside layer portion, the bump protruding from the outside layer portion and comprising a sidewall; forming a protection layer to cover the outside layer portion and the bump; removing a portion of the protection layer so as to leave a portion of the protection layer covering the sidewall of the bump; applying a bonding material to at least one of exposed surfaces of the outside layer portion, the bump, and the protection layer; attaching a support for supporting the first surface of the semiconductor substrate to the bonding material; polishing a second surface of the semiconductor substrate while the first surface of the semiconductor substrate is supported by the support; and removing the support and the bonding material after polishing the second surface of the semiconductor substrate.
