摘要:
A substrate (e.g. of silicon) which forms a volatile fluoride is etched and directionality is achieved using vibrationally excited SF 3 which has been exposed to laser irradiation. The substrate is etched through a mask having openings smaller than the diffraction limit of the laser light.
摘要:
A method of forming a polymer film containing metal therein includes the steps of providing an electrode of a metal that can be etched by a halogen, providing a substrate for the polymer film to be deposited thereon, and passing a halocarbon monomer through a plasma system so that the metal etched from the electrode forms a volatile halide and is incorporated in the polymer film that is deposited on the substrate.

摘要:
A method of plasma etching silica at a faster rate than silicon in an article containing both silica and silicon involves using a gaseous mixture containing an unsaturated halocarbon and a saturated halocarbon. The preferred halocarbons contain fluorine. A preferred embodiment is a gaseous mixture containing C 3 F 6 and C 2 F 6 .
