发明名称 METHOD FOR REDUCING THE THICKNESS OF SUBSTRATES
摘要 <p>The current invention presents a method for thinning wafers. The method uses a two-step process, whereby first the carrier wafer (2) is thinned and in a second step the device wafer (1) is thinned. The method is based on imprinting the combined thickness non-uniformities of carrier (2) and glue layer (3) essentially on the carrier (2), with a resulting low TTV of the wafer (100) after thinning.</p>
