Abstract:

A method of forming an insulation layer on a semiconductor substrate includes modifying a surface of a semiconductor substrate with a metal or a metal-containing compound and oxygen to form an insulation layer on the surface of the semiconductor substrate, wherein the insulation layer comprises the metal or metal-containing compound, oxygen, and silicon such that the dielectric constant of the insulation layer is greater relative to an insulation layer formed of silicon dioxide, and wherein the insulation layer comprises metal-oxygen-silicon bonds.

Abstract:

An electro-surgical instrument includes an elongated electrode probe for delivering electrical energy to tissue through an exposed, conductive distal tip and a handpiece that provides the electrical energy to the probe through a coupling to the proximal end of the probe. The coupling, which defines a longitudinal axis, is structured to provide a rigid yet removable connection between the probe and handpiece, and to allow the surgeon to connect the probe to the handpiece at a selected one of several discrete rotational index angles relative to the longitudinal axis.
