  • Publication number: 20040207044
    Abstract: An improved laser trimming technique allows for a portion of the laser energy to always be on a path length for creating a constructive node independently of the oxide thickness. This improvement is accomplished by forming steps in the reflective silicon that ensure constructive nodes (or prevents the formation of destructive nodes) at the thin film plane. The steps are formed using any of the following techniques: shallow trench isolation, a separate etch step, or LOCOS.

  • Patent number: 6156435
    Abstract: Provided are methods for forming a fluorocarbon polymer thin film on the surface of a structure. In one method, a monomer gas is exposed to a source of heat having a temperature sufficient to pyrolyze the monomer gas and produce a source of reactive CF.sub.2 species in the vicinity of the structure surface. The structure surface is maintained substantially at a temperature lower than that of the heat source to induce deposition and polymerization of the CF.sub.2 species on the structure surface. In another method for forming a fluorocarbon polymer thin film, the structure is exposed to a plasma environment in which a monomer gas is ionized to produce reactive CF.sub.2 species. The plasma environment is produced by application to the monomer gas of plasma excitation power characterized by an excitation duty cycle having alternating intervals in which excitation power is applied and in which no excitation power is applied to the monomer gas.
