摘要:
This invention provides a fluorine-containing copolymer having a repeat unit derived from at least one fluorinated olefin and a repeat unit derived from at least one polycyclic ethylenically unsaturated monomer having pendant hydroxyl or esterified hydroxyl groups, and optionally other repeat units, typically derived from an acrylate. These polymers have high transparency at short wavelengths such as 193 nm and 157 nm, and provide good plasma etch resistance and adhesive properties. Also provided are photoresist compositions and substrates coated therewith.
摘要:
A one or two layer coating system has been developed for plastic substrates. The one coating system low reflective layer consists of a fluorinated copolymer having the formula: VF2/TFE/HFP, VF2/HFP or VF2/TFE/PMVE. In the two coating system, the upper coating layer consists of TFE/HFP, VF2/TFE/HFP, or TFE/Perfluorodioxole, and the lower coating layer consists of VF2/TFE/HFP, VF/TFE/HFP, VAc/TFE/HFIB, or TFE graft to PVOH.
摘要:
Fluorinated polymers, photoresists and associated processes for microlithography are described. These polymers and photoresists are comprised of a fluoroalcohol functional group which simultaneously imparts high ultraviolet (UV) transparency and developability in basic media to these materials. The materials of this invention have high UV transparency, particularly at short wavelengths, e.g., 157 nm, which makes them highly useful for lithography at these short wavelengths.
摘要:
The present invention pertains to photoimaging and the use of photoresists (positive-working and/or negative-working) for imaging in the production of semiconductor devices. The present invention also pertains to novel hydroxy ester-containing polymer compositions that are useful as base resins in resists and potentially in many other applications.
摘要:
Disclosed herein are novel amorphous tetrafluoroethylene-hexafluoropropylene (TFE-HFP) dipolymers, and other copolymers containing TFE, HFP and a third monomer, many of which are more random than previous amorphous TFE-HFP copolymers, as well as a novel high productivity continuous process for making these polymers. The polymers are particularly useful in the form of coatings, films and encapsulants.
摘要:
Refrigerant compositions containing polymeric oil-return agents which solubilize or disperse mineral and synthetic oil lubricants with hydrofluorocarbon and hydrofluorocarbon/hydrochlorofluorocarbon-based refrigerants are disclosed. These polymeric oil-return agents, such as copolymers of fluorinated and non-fluorinated methacrylates, as a small proportion of an overall refrigerant composition, permit efficient return of mineral and synthetic oil lubricants from non-compressor zones back to a compressor zone in a refrigeration system operating with hydrofluorocarbon and hydrofluorocarbon/hydrochlorofluorocarbon-based refrigerants.
