- Thermal Release Tape For Hard Substrate NWS-Y5V/NWS-TS322F
Thermal Release Tape
For Hard Substrate NWS-Y5V/NWS-TS322F
Capable of Processing Brittle Wafer.
Outline
Capable of releasing/collecting semiconductor wafers at any stage by constant support of the semiconductor wafer using a supporting wafer. Es pecially recommended for semiconductor wafer processes that rire reverse-side processing.
Features
- Extremely thin grinding capability
- Eliminates warping and sagging by firmly supporting the wafer
- Easily releases at any time with heat treatment

Process Flow of Wafer Supporting System
*After removing this tape, ultralow-volume materials (organic elements) from the adhesive sheet may remain on the substrate. Particles tend to remain, especially on silicon wafers. Please confirm that residual material or particles do not cause problems with the application.
