Abstract:
A method of fabricating an intermediate structure in a porous substrate in which microdevices are fabricated and which porous substrate has a frontside with a plurality of open pores and an opposing backside wherein said plurality of pores are closed, said method comprising:disposing a patterned photolithographed mask on said backside; and removing selected portions of said backside to leave a portion of said porous substrate intact to define open pore portions and to leave a portion of said porous substrate with said backside removed to define a plurality of disconnected segments which in turn define pore walls for a subplurality of doubly-opened pores which are open on each opposing end of said pore, thereby forming an intermediate structure in which microdevices may be formed.
