Abstract:
A method for forming a micro tip for a micro probe utilized in testing semiconductor integrated circuit devices, said method comprising the steps of:depositing a thick oxide layer upon a substrate, wherein a thickness of said thick oxide layer is thick with respect to a thickness of said substrate; and performing a first lithography operation upon said substrate and layers thereof following a deposition of said thick oxide layer upon said substrate; performing a first metal sputter operation upon said substrate, following said first lithography operation performed upon said substrate and said layers thereof; performing a chemical mechanical polishing operation upon said substrate and said layers thereof following said first metal sputter operation performed upon said substrate; performing a second metal sputter operation upon said substrate, following said chemical mechanical polishing operation performed upon said substrate and said layers thereof; and defining a micro tip for a microprobe from said thick oxide layer upon said substrate through a plurality of subsequent semiconductor manufacturing operations performed upon said substrate and layers thereof, wherein a plurality of said micro tips are mass produceable and can be efficiently utilized in association with increasingly smaller sizes of semiconductor integrated circuit devices.
