标 题 :Method for making a chemical contrast pattern using block copolymers and sequential infiltration synthesis

权利人:HGST Netherlands BV
摘要:A method for making a chemical contrast pattern uses directed self-assembly of block copolymers (BCPs) and sequential infiltration synthesis (SIS) of an inorganic material. For an example with poly(styrene-block-methyl methacrylate) (PS-b-PMMA) as the BCP and alumina as the inorganic material, the PS and PMMA self-assemble on a suitable substrate. The PMMA is removed and the PS is oxidized. A surface modification polymer (SMP) is deposited on the oxidized PS and the exposed substrate and the SMP not bound to the substrate is removed. The structure is placed in an atomic layer deposition chamber. Alumina precursors reactive with the oxidized PS are introduced and infuse by SIS into the oxidized PS, thereby forming on the substrate a chemical contrast pattern of SMP and alumina. The resulting chemical contrast pattern can be used for lithographic masks, for example to etch the underlying substrate to make an imprint template.

标 题 :Synthesis and application of vapor grafted porous materials
发明人：YING JACKIE Y; MEHNERT CHRISTIAN P
权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:This invention provides an article, compositions, methods of making and uses of vapor-deposited metal compounds immobilized on porous substrates. The substrate is a porous substrate having an average pore size of at least about 8 â„« and a surface area of at least about 10 m 2 /g. The methods describe the vapor-deposition of an inorganic compound onto the substrate where the deposition is accomplished with a relatively small amount of ligand loss. The substrate can be pre-treated to achieve a uniformly dispersed metal compound deposited on the substrate. The inorganic compound can decompose into a metal compound. The article can also function as a catalyst for carbon-heteroatom coupling reactions such as carbon-carbon coupling reactions, most notably, the Heck reaction.
