Abstract:
1. A film-formation method comprising: forming a reflective layer on a first substrate, and the reflective layer having an opening portion; forming a first heat-insulating layer having a light-transmitting property over the reflective layer and the opening portion; forming a light-absorbing layer over the first heat-insulating layer; forming a second heat-insulating layer over the light-absorbing layer, the second heat-insulating layer having been selectively formed to be essentially only overlapping with the reflective layer; forming a material layer using a liquid composition containing a material over the light-absorbing layer and the second heat-insulating layer by a wet process; performing a heat treatment to the material layer so as to remove a solvent in the liquid composition; disposing the first substrate and a second substrate such that the material layer is interposed therebetween; and after performing the heat treatment, irradiating at least apart of the light-absorbing layer with laser light through the first substrate, the opening portion of the reflective layer, and the first heat-insulating layer; whereby the material, contained in the material layer formed over the part of the light-absorbing layer, deposits on the second substrate, wherein a thickness of the second heat-insulating layer is larger than a thickness of the first heat-insulating layer, wherein a difference between a reflectance with respect to the laser light of the reflective layer and that of the light-absorbing layer is more than 25%, and wherein the laser light has a repetition rate of 10 MHz or higher and a pulse width of from 100 fs to 10 ns.
