Patent number: 8932797Abstract: A photoacid generator compound has formula (I): G+Z???(I) wherein G has formula (II): In formula (II), X is S or I, each R0 is commonly attached to X and is independently C1-30 alkyl; polycyclic or monocyclic C3-30 cycloalkyl; polycyclic or monocyclic C6-30 aryl; or a combination comprising at least one of the foregoing groups. G has a molecular weight greater than 263.4 g/mol, or less than 263.4 g/mol. One or more R0 groups are further attached to an adjacent R0 group, a is 2 or 3, wherein when X is I, a is 2, or when X is S, a is 2 or 3. Z in formula (I) comprises the anion of a sulfonic acid, a sulfonimide, or a sulfonamide. A photoresist and coated film also includes the photoacid generator, and a method of forming an electronic device uses the photoresist.Type: GrantFiled: November 30, 2011Date of Patent: January 13, 2015Assignees: Dow Global Technologies LLC, Rohm and Haas Electronic Materials LLCInventors: James W.

Patent number: 8445611Abstract: The invention generally relates to novel polymers (SMAMPs) and their syntheses and use. The polymers exhibit promising properties of AMPs. In particularly, for example, a ring-opening metathesis polymerization (ROMP) platform was developed that allows syntheses of SMAMPs that employ a minimum number of norbornene-based building blocks and/or enable easy and independent variation of hydrophobic and hydrophilic groups in the monomer units and/or along the polymeric backbone to finetune and select desirable properties of the polymers.Type: GrantFiled: April 6, 2012Date of Patent: May 21, 2013Assignee: University of MassachusettsInventors: Gregory N. Tew, Ahmad E. Madkour, Karen Lienkamp, Ashlan Marie Musante
