Insulating material is deposited onto a gate dielectric surface separating two wordline stacks, the method comprising the steps of: A. Forming at least two adjacent wordline stacks over a common gate dielectric, the stacks spaced apart from one another thereby forming an open surface on the gate dielectric between the stacks; and B. Depositing by sputtering the insulating material onto the open surface of the gate dielectric separating the two wordline stacks.
