摘要:
There is provided a production process of a heat-ray shielding film-formed base member comprising the steps of mixing a sol solution, formed by using a starting raw material of trialkoxysilane or trialkoxysilane and tetraalkoxysilane, with a solution in which tin-doped indium oxide ultra-fine particles are dispersed, to make a treatment agent; and applying the treatment agent to a base member. In this production process, the treatment agent has an organic solvent having a boiling point of 100-200° C. as a dispersion medium, and the application is conducted by a means by bringing a member retaining the treatment agent into contact with the base member or by a means by spraying the treatment agent, thereby adjusting haze value of the film to be formed to 0.5% or less.

摘要:
A cleaning agent for a silicon wafer (a first cleaning agent) contains at least a water-based cleaning liquid and a water-repellent cleaning liquid for providing at least a recessed portion of an uneven pattern with water repellency during a cleaning process. The water-based cleaning liquid is a liquid in which a water-repellent compound having a reactive moiety chemically bondable to Si element in the silicon wafer and a hydrophobic group, and an organic solvent including at least an alcoholic solvent are mixed and contained. With this cleaning agent, the cleaning process which tends to induce a pattern collapse can be improved.
