    摘要: A method is disclosed for the deposition of crystalline diamond on a substrate such as a silicon wafer. A polymer (for example poly(methylmethacrylate)) is provided as a target for laser ablation using for example an ArF excimer laser or an Nd-Yag laser. The laser ablation is performed in the presence of a reactive gas such as oxygen or hydrogen. The substrate is heated to a temperature of between 450 and 700 degrees celsius.

    摘要: A dry process for forming a positive tone micro pattern by coating a substrate with an organic polymer film then with a film of an oxygen etch barrier, selected from the group consisting of films of organometallic, including organosilicon compounds and metals, exposing the etch barrier film to a low energy proton beam in a patternwise manner, and developing the pattern by means of oxygen reactive ion etching.

    摘要: Positive resists are made using polymers and copolymers of methacrylic acid, methacrylic anhydride, methyl methacrylate, methacrylimide, and N-alkyl-methacrylimides which have been nitrated in up to about 10% of the monomer units on the methyl groups branching off the polymer chain. Inclusion of the nitro groups results in an increase of over an order of magnitude in the speed of development of images when the polymers are used as positive resists.
