Abstract
A contact structure for achieving an electrical connection with a contact target is formed of a contact substrate and a plurality of contactors mounted on the contact substrate. The contactors are produced on a semiconductor substrate or other dielectric by a microfabrication technology. Each of the contactors has a contact bump to contact with the contact target. In one aspect, one of the base portions of the contactor is slidably formed on the surface of the contact substrate. A spring force is generated when the contactor is pressed against the contact target. Various types of contact structures and the associated production methods are also described.
