Title:
有孔基板の製造方法及び有孔基板
Document Type and Number:
Japanese Patent JP6788830
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent occurrence of damages such as cracking caused by application of stress on the substrate, by steps of filling resin into the hollow part of a through-hole, hardening the resin, and polishing the unnecessary part of the resin by polishing.SOLUTION: A through-electrode substrate 10 has a first surface 13 and a second surface 14. The method according to the present invention includes the steps of: preparing a substrate 12 with a through-hole 20 penetrating the first surface to the second surface; positioning a resin material so that the resin material will lie across the inside and the outside of the through-hole at least on the first surface side and filling the resin material into the through-hole; irradiating the substrate with an electromagnetic wave or a charged particle line so that the part of the resin material which overlaps with the through-hole when the substrate is seen along the normal direction of the substrate will become hardened or will continue to be hard; removing the part of the resin material which is not hardened or is continued to be hard by the irradiation step; and thermally hardening thermal resin material.SELECTED DRAWING: Figure 2
