    Method of backgrinding wafers while leaving backgrinding

    Jun 13, 20060183;32;A method of backgrinding wafers wherein backgrinding tape or a pad is applied to the chuck and not to the wafers. The backgrinding tape or pad is left on the chuck as each wafer is sequentially placed on the tape or pad, background, rinsed on the backside, removed from the tape and then cleaned on the front side and backside.

    Backgrinding remains the most popular and widely used wafer thinning method. To produce even thinner wafers, thinner than 50 m, two or more processes are often combined. The 3M Wafer Support System TM can be used in tandem with SEZ etch and/or CMP (chemical mechanical planarization) polishing for this purpose.

    Etching (microfabrication)

    Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a quot;maskingquot; material which resists etching.
