Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H  C | IPC C  H

Claim 8:
9. A method to synthesize a porous thin film, the method comprising:
forming a non-organic framework including a plurality of organic impurities, the organic impurities extending from a first end located at an upper surface of the framework to a second end contained in the framework;
removing the organic impurities to form pores extending from the upper surface of the framework to a bottom surface contained in the framework; and
coating sidewalls and the bottom surface of the pores with a pore-coating film,
wherein forming the non-organic framework includes performing an atomic layer deposition (ALD) process to deposit a metal oxide material on a substrate, the ALD process using an oxidizer that is performed at a low temperature ranging from about 50 degrees Celsius (50° C.) to about 250° C. so as to form the organic impurities comprising a carbon material.
