Abstract
A method for forming an electronic device provides a casting master having a casting surface, and deposits a substrate material onto the casting surface to form a flexible substrate sheet of predetermined thickness, wherein the flexible substrate sheet has a circuit-side surface that is formed against the casting surface. The flexible substrate sheet is released from the master and secured against a carrier, with the circuit-side surface facing outward. An electronic device is then formed on the circuit-side surface.
Claims19
A method for forming an electronic device comprising:
- forming a master having a casting surface;
- depositing a substrate material onto the casting surface to form a flexible substrate sheet of predetermined thickness, wherein the flexible substrate sheet has a circuit-side surface that is formed against the casting surface, and a back surface;
- releasing the flexible substrate sheet from the master;
- securing the flexible substrate sheet against a carrier, with the circuit-side surface facing outward;
- and
- forming the electronic device on the circuit-side surface of the flexible substrate sheet while the back surface of the flexible substrate sheet is secured against the carrier.
