Embodiment Construction

[0015] Embodiments of the present invention provide a substrate support assembly having a protective layer for enhanced plasma corrosion resistance. In one embodiment, the protective layer may be a ceramic layer including a rare earth metal. Examples of protective layers may include yttrium (Y), yttrium oxide (Y 2 o 3 ), yttrium alloys or their derivatives. The protective coating provides a corrosion-resistant surface on the substrate support assembly, thereby increasing the service life of the substrate support assembly while reducing maintenance and manufacturing costs.

[0016] FIG. 1 shows a cross-sectional view of one embodiment of a semiconductor processing chamber having a substrate support assembly 148 disposed therein and having a protective layer 136 . While one embodiment of a substrate support assembly 148 is provided here, it is contemplated that other substrate support assemblies may be adapted to benefit from the present invention.

Abstract

Embodiments of the present invention provide a substrate support assembly having a protective layer with enhanced plasma corrosion resistance. In one embodiment, a substrate support assembly includes an electrostatic chuck having an upper substrate support surface, and a protective layer disposed on the electrostatic chuck, wherein the protective layer is made of a ceramic material including a rare earth metal.

Description

technical field [0001] Embodiments of the present invention generally relate to a semiconductor processing chamber, and more particularly to a substrate holder having a protective layer suitable for use in a semiconductor processing chamber. Background technique [0002] Semiconductor processing involves a number of different chemical and physical processes to produce tiny integrated circuits on a substrate. The layers of material making up the integrated circuit are produced by chemical vapor deposition, physical vapor deposition, epitaxial growth, and the like. Certain material layers are patterned by using photoresist masks and wet or dry etching techniques. The substrate used to form the integrated circuit may be silicon, gallium arsenide, indium phosphide, glass, or other suitable materials. [0003] A typical semiconductor processing chamber includes a chamber defining a process region, a gas distribution assembly adapted to provide gases from a gas source to the pro...
