Patent ID: 7605057

Claim:
A semiconductor device manufacturing method having a step of cutting a semiconductor substrate, on a primary side of which a plurality of integrated circuits are arrayed, along scribing lines extending lengthwise and widthwise on the semiconductor substrate to separate the semiconductor substrate into integrated circuit chips, the semiconductor device manufacturing method comprising: forming the plurality of integrated circuits on the primary side of the semiconductor substrate; attaching a dicing tape to the primary side of the semiconductor substrate to secure the semiconductor substrate after the forming step; cutting the semiconductor substrate along the scribing lines from the back side to form the integrated circuit chips after the attaching step bonding a supporting member to a back side of the semiconductor substrate which is opposite to the primary side after the step of cutting the semiconductor substrate has been performed; and cutting the supporting member along the scribing lines from the back side to separate the semiconductor substrate into a plurality of supported integrated circuit chips, wherein the supporting member has a supporting block region located beneath each of the integrated circuit chips, a thinned region which is thinner than the supporting block regions and a void region which is an opening in the supporting member in at least a part of an outer peripheral region of each of the supporting block regions, the outer peripheral region located beneath the scribing lines and then removing the supported integrated circuit chips from the dicing tape after the cutting step.
