A method of forming at least one raised metallic contact on an electrical circuit comprising providing a composite base substrate, which is defined by at least a first conductive layer, a dielectric material, and a second conductive layer; removing a portion of the first conductive layer to expose the dielectric material; removing the exposed portion of the dielectric material to the second conductive layer, thereby forming a depression; depositing at least one layer of conductive material on at least side wall portions of the said depression; removing the second conductive layer; and completely removing the dielectric material to the first conductive layer thereby forming a raised metallic contact, which extends perpendicularly away from the first conductive layer.
A method for producing a transistor using anodic oxidation.

DISPOSABLE, SLIP-ON DANGLER HEADS... *SAVE PLATING TIME *PROLONG CABLE LIFE AND *PERFORM FOR PENNIES
NO LOST PLATING TillE. Slip off built-up heads. and sJipon fresh, new heads without removing Dangler Assembly from barrel. LONGER CABLE LIFE. Removing heads bafore the plating build-up is excessive, prolongs the life of the Dangler Assembly. INEXPENSIVE. Field studies have shown that using our disposable heads costs just pennies per barrel load to use.
CHANGE HEADS IN SECONDS - all non-magnetic coatings· applied over steel - all insulating coatings applied over non-ferrous metals - available with or without statistics and memory - activated interface - easy to read digital display - simple and fast calibration
