- arithmetic mean roughness Ra of the other surface (2nd surface) was 0.05 micrometer.
- Example 3 Except for using a release film made of polyethylene terephthalate film (product name “Diafoil (registered trademark) T-100 38”, thickness: 38 ⁇ m, manufactured by Mitsubishi Plastics, Inc.) for semiconductor processing as in Example 2. A sheet was produced. The arithmetic average roughness Ra on both surfaces of the release film was 0.05 ⁇ m.
- a release film made of polyethylene terephthalate film product name “Diafoil (registered trademark) T-100 38”, thickness: 38 ⁇ m, manufactured by Mitsubishi Plastics, Inc.
- Test Example 2 (Measurement of peel force ⁇ )
- a laminate composed of 10 semiconductor processing sheets was prepared and stored at 40 ° C. for 3 days.
- One sheet for semiconductor processing is taken out from this laminate, and the first surface of the base material is bonded to a stainless steel plate using a double-sided adhesive tape, and a universal tensile testing machine (product name: Tensilon UTM, manufactured by Orientec Co., Ltd.). -4-100). Thereafter, only the release film was peeled in the 180 ° direction at a tensile speed of 300 mm / min under the conditions of a temperature of 23 ° C. and a relative humidity of 50% RH.
- the roll-shaped semiconductor processing sheet thus obtained was stored for 3 days in a moist heat accelerator (manufactured by ESPEC, product name “SH641”) set to a dry state at 40 ° C.
- the semiconductor processing sheet was When the energy ray-curable material was included, the laminate was stored in a state where it was shielded from light.
- the semiconductor processing sheet wound up into a roll was fed out using a wafer mounter (product name “RAD-2500m / 8” manufactured by Lintec Corporation). And the area
- Test Example 4 (Mount evaluation) In the same manner as in Test Example 3, a roll-shaped semiconductor processing sheet was prepared and stored at 40 ° C. for 3 days. Then, using a wafer mounter (product name “RAD-2500m / 8” manufactured by Lintec Corporation), the main use part was peeled off from the release film of this roll, and the main use part was attached (mounted) to the semiconductor wafer. . This operation was repeated 20 times continuously, and when it was successfully completed, it was evaluated as “good”. On the other hand, when a defect occurred in the mount due to defective peeling of the main use part from the release film, it was evaluated as x. The results are shown in Table 2.
- Table 1 summarizes the configurations of the semiconductor processing sheets produced in the examples and comparative examples. The details of the abbreviations listed in Table 1 are as follows.
- Base material -PVC: polyvinyl chloride-EMAA: ethylene-methacrylic acid copolymer-EVA: ethylene-vinyl acetate copolymer-PP: polypropylene [release film]
- PET Polyethylene terephthalate
- Test Example 5 Evaluation of light transmittance
- a wafer mounter product name “RAD-2500m / 8”
- DISCO product name “DFD-651”
- Dicing conditions ⁇ Work (object to be cut): Silicon wafer (size: 6 inches, thickness: 350 ⁇ m, sticking surface: mirror) ⁇ Dicing blade: manufactured by Disco Corporation, product name “27HECC” ⁇ Blade rotation speed: 30,000rpm ⁇ Dicing speed: 10 mm / second ⁇ Cutting depth: Cutting from the surface of the substrate opposite to the dicing machine table to a depth of 20 ⁇ m ⁇ Dicing size: 5 mm ⁇ 5 mm
- the semiconductor processing sheets of the examples were excellent in light transmittance, and excellent evaluation was obtained in both feeding from the roll and mounting.
- the semiconductor processing sheet of the comparative example a problem occurred in either the feeding from the roll or the mounting.
- the semiconductor processing sheet according to the present invention is suitably used as, for example, a dicing sheet, a dicing die bonding sheet, a protective film forming layer integrated dicing sheet, or the like.
