  • Polycarbocyclic derivatives for modification of resist, optical and etch resistance properties
    Patent number: 7326510
    Abstract: Mixed carbocycle derivatives containing at least two carbocycles per molecule from the group of anthracenes, adamantanes and steroids with functionalized carbon chains are synthesized and used as modifiers of resist properties and especially etch resistance enhancement and absorption characteristics. These derivatives are characterized by formulas I-V, where A and R may be an anthryl- and/or an adamantyl- and/or a steroid moiety. Methods for the preparation of the above compounds are disclosed.
    Type: Grant
