Abstract:
Implementations of the present disclosure relate to a sputtering target for a sputtering chamber used to process a substrate. In one implementation, a sputtering target for a sputtering chamber is provided. The sputtering target comprises a sputtering plate with a backside surface having radially inner, middle and outer regions and an annular-shaped backing plate mounted to the sputtering plate. The backside surface has a plurality of circular grooves which are spaced apart from one another and at least one arcuate channel cutting through the circular grooves and extending from the radially inner region to the radially outer region of sputtering plate. The annular-shaped backing plate defines an open annulus exposing the backside surface of the sputtering plate.

Claim (Index 16):
A magnetron sputtering target assembly for a sputtering chamber, the sputtering target assembly comprising:\n (a) a heat exchanger housing capable of holding heat transfer fluid about a plurality of rotatable magnets; (b) a sputtering target abutting the housing such that the heat transfer fluid contacts a backside surface of the sputtering target, the sputtering target comprising a backing plate having the backside surface, the backside surface including:\n (i) radially inner, middle and outer regions, wherein the radially middle region has a plurality of concentric circular grooves located at the backside surface, and \n (ii) a plurality of arcuate channels extending from the radially inner region to the radially outer region of the backside surface; and \n (c) a sputtering plate mounted on the front surface of the backing plate wherein at least one of the backing plate and the sputtering plate comprise a material selected from Al0.5Cu, Al1.0Si, Al0.5Cu1.0Si, pure aluminum, copper, chrome, titanium, tungsten, molybdenum, cobalt, tantalum, Li\u2014P\u2014O\u2014N, germanium, GeS 2 , silicon, SiO 2 , quartz, combinations thereof and alloys thereof.
