Abstract:
An Atomic Layer Deposition (ALD) configured to deposit a metal oxide layer onto an organic photoresist on a substrate using a highly reactive organic metal precursor. By using a highly reactive metal precursor, the rate of growth of the metal oxide layer is very fast, creating a “seal” that effectively protects the organic photoresist from loss and degradation from subsequent exposure to oxygen species during subsequent ALD cycles. The ability to deposit metal oxide layers means metal oxide spacers can be used in multi-patterning, resulting in highly uniform, dense lines, and the elimination of photolithography-etch steps.

Claim (Index 1):
An Atomic Layer Deposition (ALD) tool comprising:\n a processing chamber; a substrate holder for holding a substrate with an organic photoresist formed thereon for processing in the processing chamber; and a controller including executable instructions that are arranged to control the ALD tool during one or more ALD cycles, the control of the ALD during the one or more ALD cycles characterized by: a first half-cycle using an organic metal precursor that is introduced into the processing chamber under the control of the controller, the organic metal precursor resulting in a deposition of a metal oxide layer onto the organic photoresist on the substrate; and a second half-cycle using an oxygen species that is introduced into the processing chamber under the control of the controller, the oxygen species acting to degrade the organic photoresist, wherein the organic metal precursor is sufficiently reactive to seal the organic photoresist with the deposited metal oxide layer in three ALD cycles or less.
