摘要:
A process for depositing a lithium cobalt oxide-based thin film on a substrate in which the Li-stoichiometry (Li x CoO 2 ) can be tuned within the limits 0.5≤ x≤1.1 using a standard stoichiometric LiCoO 2 target material combined with a second target material (Co or Co a O b ) resp. Li or Li 2 O as the case may be either on a dual magnetron or on single magnetrons in adjacent coating chambers. In case of the usage of a dual magnetron, preferentially bipolar pulsed DC with a controlled duty cycle on each of the two cathodes is used in order to tune the stoichiometry of the coating. Alternatively, the LiCoO 2 target is powered with unipolar pulsed DC to a power P 1 and the Co or Co a O b resp. Li or Li 2 O target is powered with DC or unipolar pulsed DC to a power P 2 in order to tune the stoichiometry. In case of the usage of single magnetrons in adjacent coating chambers, the power loads on the Li or Li 2 O resp. Co or Co a O b resp. Li or Li 2 O targets are tuned in order to achieved the required stoichiometry.

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.
