METHOD FOR MANUFACTURING ANTENNA PART

摘要

Provided is a method of manufacturing an antenna part that can be produced easily and inexpensively, the method comprising the steps of: forming a coil part 11 by a wire material 13 having an insulation coating 16, and removing the insulation coating 16 from both end portions 11a of the coil part 11; forming a connection region 12a of an electrically-conductive metal on the semiconductor substrate 12, and further forming a solder layer 14 on the connection region 12a; wiring the coil part 11 on the connection region 12a so that each end portion 11a of the coil part 11 to be in contact with the solder layer 14; and melting the solder layer 14 by heat to allow each end portions 11a to enter into the solder layer 14, and thus to electrically connect the connection region 12a and the coil part 11 through the solder layer 14.

1. A method of manufacturing an antenna part having a coil part and a semiconductor substrate, the method comprising the steps of:
(A) forming the coil part by a wire material having an insulation coating, and removing the insulation coating from both end portions of the coil part; (B) forming a connection region of an electrically-conductive metal on a surface of the semiconductor substrate, and further forming a solder layer on a surface of the connection region; (C) wiring the coil part on the connection region so that each end portion of the coil part to be in contact with the solder layer; and (D) melting the solder layer by heat to allow each end portion to enter into the solder layer, and thus to electrically connect the connection region and the coil part through the solder layer.
