While a transfer surface 10a of a transfer plate 10 having a predetermined surface roughness is brought into contact with a plurality of bumps 44B on a contact sheet 44 formed on a substrate 44M having the coefficient of linear expansion larger than that of the transfer plate 10 at a predetermined pressure, the substrate 44M and the transfer plate 10 are heated to a predetermined temperature to recover the surface roughness of the bump 44B to a predetermined value.
摘要:
A solid polymer electrolyte film is composed of at least an ion exchange resin. The solid polymer electrolyte film of the present invention is also characterized in having beaded silica dispersed therein. The ratio of the ion exchange resin and the beaded silica (beaded silica/ion exchange resin) is about 1 to 50 wt %, for example. The preferred beaded silica has a primary particle size of 50 nm or less as measured with the help of the BET method, and has a particle size of 60 nm or more as measured with the help of dynamic light scattering.
