发明名称 METHOD OF PROCESSING WAFER
摘要 The invention relates to a method of processing a wafer, having on one side a device area with a plurality of devices partitioned by a plurality of division lines and a peripheral marginal area having no devices and being formed around the device area, wherein the device area is formed with a plurality of protrusions protruding from a plane surface of the wafer. The method comprises attaching a protective film, for covering the devices on the wafer, to the one side of the wafer, wherein the protective film is adhered to at least a part of the one side of the wafer with an adhesive, and providing a carrier having a curable resin applied to a front surface thereof. The method further comprises attaching the one side of the wafer, having the protective film attached thereto, to the front surface of the carrier, so that the protrusions protruding from the plane surface of the wafer are embedded in the curable resin and a back surface of the carrier opposite to the front surface thereof is substantially parallel to the side of the wafer being opposite to the one side, and grinding the side of the wafer being opposite to the one side for adjusting the wafer thickness.

主权项 1. A method of processing a wafer, having on one side a device area with a plurality of devices partitioned by a plurality of division lines and a peripheral marginal area having no devices and being formed around the device area, wherein the device area is formed with a plurality of protrusions protruding from a plane surface of the wafer and the method comprises: attaching a protective film, for covering the devices on the wafer, to the one side of the wafer, wherein the protective film is adhered to at least a part of the one side of the wafer with an adhesive; providing a carrier having a curable resin applied to a front surface thereof; attaching the one side of the wafer, having the protective film attached thereto, to the front surface of the carrier, so that the protrusions protruding from the plane surface of the wafer are embedded in the curable resin and a back surface of the carrier opposite to the front surface thereof is substantially parallel to the side of the wafer being opposite to the one side; and grinding the side of the wafer being opposite to the one side for adjusting the wafer thickness.
