Title:
ELECTRIC CONTACT STRUCTURE FROM FLEXIBLE WIRE
Document Type and Number:
Japanese Patent JP2001077250
Kind Code:
A
Abstract:

To make improvements in an interconnection between microelectronic components by a method wherein a flexible extension element is mounted on a contact region on the electronic component and so formed as to be elastic.

A wire 502 is wrapped up in or covered with a first inner coating layer 520, and the first inner coating layer 520 is coated with a second outer coating layer 522 for the formation of a wire stem 530. The first layer 520 of the wire stem 530 is made to cover a terminal 512 as a contacting region on a semiconductor substrate 508 where the end 502a of the wire 502 is bonded, and the wire 502 of soft gold material is mounted and fixed to the terminal 512. By this setup, improvements can be made in an interconnection between microelectronic components.
