Claim:
1. A mold structure having high-precision multi-dimensional components comprising: a plurality of semiconductor substrates; a first oxide layer superimposed on a top of a first semiconductor substrate of said plurality of semiconductor substrates; a second oxide layer superimposed on a top of a second semiconductor substrate of said plurality of semiconductor substrates; integrated designs patterned in at least one of said oxide layers; and said first and second semiconductor substrates bonded to one another by dielectric bonding into a three dimensional (3D) mold such that said first oxide layer only makes partial contact with said second oxide layer such that a portion of the first oxide layer avoids contact with the second oxide layer, the portion of the first oxide layer directly opposite a surface portion of the second semiconductor substrate, the surface portion of the second semiconductor substrate being free of said second oxide layer, said 3D mold selectively filled with a filling material to form a molded high-precision multi-dimensional component, the molded high-precision multi-dimensional component providing a precise replica of said 3D mold structure having multiple patterned layers.
