Patent ID: 7165322

Claim:
A socket contact formation process for forming a plurality of socket contacts in a substrate, the plurality of socket contacts having a spacing therebetween for mating with contacts of an IC chip for use in the testing thereof, comprising: forming a contact head from a conductive material as at least one member of a socket contact having at least two members forming portions thereof, the contact head for contacting one of the contacts of the IC chip for use in the testing thereof; forming a contact body from a doped semiconductive material configured to be electrically conductive as a member of a socket contact having at least two members forming portions thereof, the contact body formed from a doped semiconductive material for use in the testing of the IC chip; and joining the contact head and the contact body forming a socket contact having at least two members forming portions thereof, the joined contact head and the contact body having at least a portion of the contact head contacting at least a portion of the contact of the IC chip during the testing thereof.
