1. A method of manufacturing a semiconductor integrated device, comprising:
- a first step of laminating a semiconductor substrate on which a plurality of semiconductor chips are formed and a support substrate with resin mixed with microparticles being interposed between the semiconductor substrate and the support substrate;
a second step of pushing the support substrate against the semiconductor substrate;
a third step of arranging wiring to achieve contact from the semiconductor chips; and
a fourth step of dividing the semiconductor chips alone scrub lines to form the semiconductor integrated device, and whereinin the second step, the support substrate is pushed against the semiconductor substrate while keeping a distance between the semiconductor substrate and the support substrate larger than the maximum particle diameter of the microparticles.

4. A method of manufacturing a semiconductor integrated device, comprising:
-
a first step of coating a first resin layer mixed with microparticles on at least one surface of a semiconductor substrate on which a semiconductor integrated circuit is formed; a second step of hardening the first resin layer coated in the first step; and a third step of coating a second resin layer not containing microparticles on the first resin layer hardened in the second step, wherein in the second step, hardening is carried out so that the film thickness of the first resin layer after hardening is kept larger than the maximum particle diameter of the microparticles. - View Dependent Claims (5)
