Patent ID: 7727809

Claim:
A manufacturing method of a semiconductor device, comprising: arranging a plurality of semiconductor integrated circuits in a matrix over a support unit so as to have a row interval of x (x>0) and a column interval of y (y>0); temporarily attaching the plurality of semiconductor integrated circuits to a first flexible substrate row by row while changing the row interval to a (a>x) without changing the column interval; arranging a plurality of antennas in a matrix over a second flexible substrate so as to have a column interval of the a and a row interval of b (b>y); moving the second flexible substrate in a row direction of the plurality of antennas so as to intersect with the row direction of the plurality of semiconductor integrated circuits over the first flexible substrate; and transferring the plurality of semiconductor integrated circuits from the first flexible substrate onto the plurality of antennas, allowing the plurality of semiconductor integrated circuits to be separated from the first flexible substrate, wherein the attachment of the plurality of semiconductor integrated circuits to the first flexible substrate is performed by the steps of: interposing the first flexible substrate between the support unit and a pickup unit having a plurality of projections; and attaching the first flexible substrate to the plurality of semiconductor integrated circuits by moving the pickup unit.
