Patent ID: 7363705

Claim:
A method for creating a contact structure, comprising: (a) forming compliant probe structure electrochemically, comprising: (i) forming a first layer on substrate, comprising: a. depositing a first material selected from a conductive structural material or a conductive sacrificial material; b. depositing a second material selected from the conductive structural material or the conductive sacrificial material, wherein the second material is different from the first material, and c. planarizing both the first and second materials; (ii) forming and adhering each of one or more successive layers to the first layer and/or to a previously formed successive layer, comprising: a. depositing a first material selected from a conductive structural material or a conductive sacrificial material; b. depositing a second material selected from the conductive structural material or the conductive sacrificial material, wherein the second material is different from the first material, and c. planarizing both the first and second materials; and (b) forming a contact tip having a desired configuration on the compliant probe structure; (c) after formation of a plurality of layers of the compliant probe structure, removing sacrificial material from a plurality of layers of the structural material.
