Method and apparatus for forming glass layer, method and apparatus for forming metal layer, and electronic component manufacturing method

A method for forming a glass layer, comprising the steps of:

• placing a workpiece into a rotatable container;
• spraying a glass slurry onto the workpiece while rotating the container to form a green glass layer on the surface thereof;
• and
• heating the workpiece while rotating the container so as to dry the green glass layer;
• wherein
• the glass slurry comprises a glass powder, a binder resin, and a solvent;
• the ratio by weight of the glass powder to the binder resin contained in the glass slurry is in the range of approximately 80:20 and approximately 25:70, and the ratio by weight of the glass powder and the binder resin in total to the solvent contained in the glass slurry is in the range of approximately 70:30 to approximately 20:80;
• the average grain diameter of said glass powder is in the range of about 0.1 μm to about 10 μm;
• and
• the viscosity of said glass slurry is in the range of about 0.01 Pa·s to about 10 Pa·s.
