Patent ID: 8759152

Claim:
A method of forming a semiconductor structure comprising: forming an array of interposer units by selecting each interposer unit in said array from a set of at least two interposer units, wherein each of said at least two interposer units is configured to fit into a same space in said array and provide different configurations in electrical connections therethrough, and each interposer unit in said array is held at a fixed position relative to other interposer units within said array without being attached to any structure at a time of formation of said array of interposer units; and bringing each of a first semiconductor chip and a second semiconductor chip in physical contact with, and attaching said first semiconductor chip and a second semiconductor chip to, said array of interposer units after formation of said array of interposer units and while each interposer unit in said array is held at said fixed position relative to other interposer units within said array.
