Patent ID: 8828246

Claim:
A method of fabricating micro-devices for biological and medical applications, wherein the method uses microelectronics processes and comprises the following steps: providing a substrate material having a surface region; adding a deposit material to the surface region of said substrate material; patterning said deposit material using photolithography and/or etching processes to form a portion of recessed areas; depositing material S onto the surface region of said deposit material and filling said recessed areas; polishing material S via CMP to remove material S from top surface of said deposit material and leaving sufficient amount of material S in said recessed area coplanar with the top surface of said deposit material; depositing material C onto the surface region of material S and said deposit material; depositing material D onto the surface region of material C; patterning material D and material C which is selective to materials S; etching material S which is selective to the deposit material, the substrate, material C, and material D and then completely removing remaining material S to form a hollow container; filling container with desired compound; sealing said container by applying a film material to the surface of material D; and patterning material D and said film material which is selective to material C to form a micro-device with micro-container filled with desired compound.
