Patent ID: 7494555

Claim:
A method of microfabricating an elastomeric structure, comprising: microfabricating a first elastomeric layer, wherein the first elastomeric layer is fabricated on a first micromachined mold having at least one raised protrusion which forms at least one recess in the bottom of the first elastomeric layer; microfabricating a second elastomeric layer, wherein the second elastomeric layer is fabricated on a second micromachined mold having at least one raised protrusion which forms at least one recess in the bottom of the second elastomeric layer; positioning the second elastomeric layer on top of the first elastomeric layer such that at least one recess in the second layer substantially perpendicularly passes over at least one recess in the first layer; and bonding a bottom surface of the second elastomeric layer onto a top surface of the first elastomeric layer.
