Title: Screen mask, its production, and fluorescent display tube
Inventor: KAWATSU KUNIAKI
IPC: B41C1/14
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To accurately form a through-hole having microscopic inside diameter in film thickness printing. SOLUTION: A screen mask 1 (mask 1) consists of a meshy member 2 having a small mesh on a sqeegee side, a meshy member 3 having a large mesh on a body side to be printed and a paste impervious region 4 which is formed of emulsion and has a reverse truncated cone shape. The paste impervious region 4 is obtained by performing exposure to emulsion through the circular hole of a photographic plate and making light radiately inccident into emulsion by diffracted light and performing development treatment therefor. The mask 1 is placed on the upper face of a glass substrate 12 by holding the meshy member 3 below. Paste is put on the upper face of the meshy member 2 and is squeezed. Paste is transferred on the glass substrate 12 and an insulated layer 11 having a taper through-hole 10 is formed.  Since the circumference of the through-hole 10 is formed into a taper face, paste does not fall toward the inside and the exposed part of the glass substrate is not buried by dropped paste. Even the through-hole of about 0.3mm diameter is surely formed.
