Patent ID: 8709945

Claim:
A method for providing electrical connection(s) through a silicon substrate, comprising the steps of: opening a hole into the silicon substrate; depositing electrical insulator material(s) inside the hole in the silicon substrate; Patterning one or more hole(s) inside the insulator material(s) inside the hole in the silicon substrate; printing electrical conductor material(s) into the hole(s) inside the insulator material(s); using the dried-ink conductor material(s) formed using the printed electrical conductor material(s) as part of or all of the conductor material(s) for providing electrical connection(s) from a front surface to a back surface of the silicon substrate; wherein the step of, depositing the electrical insulator material inside the hole in the silicon substrate comprising a step of depositing developed photo-resist material(s) as the electrical insulator material for insulating the silicon substrate and the conductor material(s) inside the hole.
