发明名称 METHOD OF ATTACHING WAFER TO SHEET
摘要 A wafer attaching method of attaching a wafer having a warp to a sheet includes a wafer warp detecting step of detecting a surface shape of the wafer, a wafer positioning step of applying a photocuring liquid resin to the sheet and positioning the wafer so that a predetermined surface of the wafer corresponding to attaching conditions preset in a resin bonding apparatus is opposed to the sheet and the liquid resin according to the preset attaching conditions and the surface shape detected above, and a wafer attaching step of pressing the wafer against the liquid resin to thereby spread the liquid resin over the entire area where the wafer and the sheet are superimposed, next removing the pressure applied to the wafer, and next applying light to the liquid resin to cure the liquid resin, thereby attaching the predetermined surface of the wafer to the sheet.
