Patent ID: 7246646

Claim:
An apparatus for production of an adhesive wafer by hot pressing a die attach film comprising a separation film on one surface of which an adhesive is provided, to an entire back surface of a wafer having a planar shape and peeling off the separation film from the wafer to thereby transfer the adhesive to the entire back surface of the wafer, comprising: a table having substantially the same planar shape as the planar shape of said wafer, provided to be able to be heated by a heating unit, and able to carry and fix said wafer, a feed roller feeding out a die attach film, a recovery roller taking up die attach film fed out from said feed roller; a pressing roller, provided between said recovery roller and said feed roller and movable reciprocatively in a parallel direction with said table, relative to said table, hot pressing said die attach film held by predetermined tension to a wafer carried on and fixed to said heated table; and a guide roller arranged above said pressing roller, guiding said die attach film between said pressing roller and recovery roller, and working together with said pressing roller to move reciprocatively in a parallel direction to said table, relative to said table, wherein: when said pressing roller and guide roller move to the recovery roller side, relative to said table, said pressing roller presses and hot presses said die attach film on the wafer heated on said table, in the state where the adhesive adhering to the wafer is heated and softened through the wafer, when the pressing roller and guide roller move to the feed roller side relative to said table, said guide roller pulls the die attach film, hot pressed to the wafer, to peel off the softened adhesive from the separation film and leave it on the wafer and to make the adhesive, of regions other than the wafer region, remain stuck to the separation film and peel off with the separation film from the wafer, and said table is fixed to a main body of said apparatus through a heat insulating collar and a clearance is formed with said main body of said apparatus.
