Abstract:
A method for producing a contact structure, comprising the following steps of:(a) forming a sacrificial layer on a surface of a base substrate; (b) forming a photoresist layer on the sacrificial layer; (c) aligning a photo mask over the photoresist layer and exposing the photoresist layer through the photo mask, the photo mask including an image of contactors; (d) developing patterns of the image of the contactors on a surface of the photoresist layer; (e) forming the contactors made of conductive material in the patterns on the photoresist layer by depositing the conductive material; each of the contactors having an upper end, a straight beam portion with a lower end as a contact point, a return portion to create a predetermined gap with the straight beam portion, and a diagonal beam portion provided between the upper end and the straight beam portion to function as a spring; (f) stripping the photoresist layer off; (g) removing the sacrificial layer so that the contactors are separated from the silicon substrate; and (h) mounting the contactors on a contactor carrier having through holes to receive the contactors therein.
