  • Methods of producing structures using a developer-soluble layer with multilayer technology
    Patent number: 8877430
    Abstract: Methods of forming microelectronic structures using multilayer processes are disclosed. The methods comprise the use of a developer-soluble protective layer adjacent the substrate surface in a multilayer stack to protect the substrate during pattern transfer. After etching, the pattern is transferred into the developer-soluble protective layer using a developer instead of etching required by previous methods. Conventional developer-soluble anti-reflective coatings and gap-fill materials can be used to form the protective layer. Custom layers with developer solubility can also be prepared. Microelectronic structures formed by the above processes are also disclosed.

  • Fluorinated polyimides with fluorene cardo structure as optical materials that have low absolute thermo-optic coefficients
    Patent number: 8668992
    Abstract: The present invention provides new polyimide materials suitable for use in optically transparent fiber composites, ribbon composites, and optical communications applications. The polyimide compounds include monomeric repeat units comprising a fluorinated moiety and a fluorene cardo structure. The polyimides exhibit good optical transparency and have a low absolute thermo-optic coefficient (|dn/dT|).
