Patent ID: 8636876

Claim:
A method of depositing a LiCoO 2 layer, comprising: placing a substrate in a reactor; flowing a gaseous mixture including argon and oxygen through the reactor; applying pulsed DC power to a densified conductive ceramic LiCoO 2 sputter target having a resistivity of about 3 kΩ-10 kΩ, the densified conductive ceramic LiCoO 2 sputter target being positioned opposite the substrate, wherein the conductive ceramic LiCoO 2 sputter target comprises Li and Co oxides, Li and Co metallic additions, and at least one dopant of Ni, Si, or Nb; applying an RF bias power to the substrate; and filtering the RF bias power with a narrow-band rejection filter from coupling into the pulsed DC power, wherein a crystalline layer of LiCoO 2 having a columnar structure is deposited over the substrate.
