Abstract

Implementations of a method of increasing the adhesion of a tape. Implementations may include: mounting a tape to a frame, mounting a substrate to the tape, heating the tape after mounting the substrate at one or more temperatures for a predetermined period of time, and increasing an adhesion of the tape to the substrate through heating the tape.

Claims (10)

1. A method of increasing an adhesion of a dicing tape, the method comprising:

mounting the dicing tape to a frame;

adhering a substrate directly to the dicing tape through mounting the substrate to the dicing tape after the dicing tape is mounted to the frame;

heating only the dicing tape and the substrate after mounting the substrate at one or more temperatures for a predetermined period of time to increase the adhesion of the dicing tape to the substrate through the heating of the dicing tape; and

removing one or more portions of the substrate through releasing the dicing tape from the one or more portions after heating the dicing tape.

2. The method of claim 1 , wherein the one or more temperatures is a single temperature during the predetermined period of time.

3. The method of claim 1 , wherein heating the dicing tape further comprises heating using a heating chuck.

4. The method of claim 1 , wherein heating the dicing tape further comprises heating using two or more heating chucks.

5. The method of claim 1 , wherein the one or more temperatures are less than 100 C.

6. The method of claim 1 , wherein the one or more portions of the substrate are semiconductor die.
