摘要： A method for sawing a wafer includes the following steps. A wafer which has an active surface, a back surface and a plurality of longitudinal and transverse sawing lines is provided, wherein the sawing lines are located on the active surface so as to define a plurality of dies. A multiple-type tape is attached on the active surface of the wafer, wherein the multiple-type tape includes a first tape and a second tape, the second tape is located between the first tape and the active surface of the wafer, and the second tape is transparent. The back surface of the wafer is grinded. The first tape is removed. Finally, the wafer including the second tape is sawn along the sawing lines so as to separate the dies from one another.

摘要： An adhesive pattern for attaching a semiconductor chip onto a non-uniform substrate is disclosed. The adhesive pattern comprises a double-k pattern formed on the substrate. The double-k pattern includes a longest major line and four shorter lines connected to the major line. The non-uniform substrate has a conductive circuit and a solder mask formed on the substrate including the circuit. The substrate has a die covering region for receiving the semiconductor chip. The conductive circuit of the substrate comprises a plurality of conductive traces unequally distributed on the die covering region. The double-k adhesive pattern of the present invention is applied onto the non-uniform substrate by a dispenser in a manner that the area on the substrate defined between the major line and the border of the die covering region has a trace density lower than the other area on the substrate.
