Abstract
A method and apparatus for forming a micro tip for a micro probe utilized in testing semiconductor integrated circuit devices. A thick oxide layer is deposited upon a substrate initially to form the micro tip. The micro tip for the micro probe can be defined from the thick oxide layer upon the substrate through a plurality of subsequent semiconductor manufacturing operations performed upon the substrate and layers thereof. A plurality of micro tips can be mass produced and efficiently utilized in association with increasingly smaller sizes of semiconductor integrated circuit devices.
