Abstract:
A method for manufacturing a microfabricated device, comprising the steps of:forming a first conductive connection on a first insulating layer;forming a conductive post on said first conductive connection;forming a second insulating layer via dry film lamination on said first conductive connection, said first insulating layer, and said conductive post;exposing said conductive post by removing a portion of said second insulating layer; andforming a second conductive connection on said second insulating layer such that said second conductive connection is electrically coupled to said first conductive connection via said conductive post,wherein said forming a conductive post step includes the steps of:forming a sacrificial mask layer on said microfabricated device, said sacrificial mask layer having a hole exposing a portion of said first conductive connection;applying conductive material to said exposed portion of said first conductive connection subsequent to said forming a sacrificial mask layer step; andremoving said sacrificial mask layer subsequent to said applying step.
