[PROBLEM] To provide a laminated body and so forth that makes it possible to reduce cracking that would otherwise occur at the chip side face during dicing. [SOLUTION MEANS] This relates to a laminated body comprising a dicing sheet and a semiconductor backside protective film. The dicing sheet comprises a base layer and an adhesive layer arranged over the base layer. The semiconductor backside protective film is arranged over the adhesive layer. Tensile storage modulus of the semiconductor backside protective film following curing is not less than 1 GPa over the entire range 23 C. to 80 C.


[PROBLEM] To provide a laminated body and so forth that makes it possible to prevent pieces of post-dicing semiconductor backside protective film from sticking to one another. [SOLUTION MEANS] This relates to a laminated body comprising a two-sided adhesive sheet and a semiconductor backside protective film arranged over the two-sided adhesive sheet. The two-sided adhesive sheet comprises a first adhesive layer, a second adhesive layer, and a base layer. The base layer is disposed between the first adhesive layer and the second adhesive layer. The first adhesive layer has a property such that application of heat causes reduction in the peel strength thereof. The first adhesive layer is disposed between the semiconductor backside protective film and the base layer.

The present invention is a transparent conductive film having a flexible transparent base and a transparent conductive layer made of a crystalline conductive metal oxide that is formed on one surface of the flexible transparent base, in which the thickness of the flexible transparent base is 80 m or less, and the difference H_(1)H_(2 )between the dimensional change rate H_(1 )when the transparent conductive film is heated at 140 C. for 30 minutes and the dimensional change rate H_(2 )when the transparent conductive layer is removed from the transparent conductive film by etching and the transparent conductive film is heated at 140 C. for 30 minutes is 0.02 to 0.043%. Because of that, the level difference at the pattern boundary when the film is assembled into a touch panel, etc. is decreased and the deterioration of the appearance can be also suppressed.

A pasting roller has brush bristles planted in a surface thereof in straight lines or spirally to form a plurality of rows at predetermined intervals on the roller surface. An adhesive sheet S is pasted to work while moving the pasting roller and the work, which is the recipient, relative to and crossing each other. In this pasting process, a rotating speed of the pasting roller is adjusted according to a surface configuration of the work to render the pressure on the adhesive sheet constant.
