  • Patent number: 11952449
    Abstract: The invention is related to a class of hydrophilic poly(meth)acrylamide-based copolymers each comprising dangling (i.e., pendant) reactive chains each terminated with a carboxyl group groups and at least 50% by mole of (meth)acrylamide repeating units relative to all repeating units of the hydrophilic poly(meth)acrylamide-based copolymer. The hydrophilic copolymers have a relatively high affinity to a base coating of a polyanionic polymer on a medical device or contact lens and are highly reactive towards azetidinium groups of an azetidinium-containing polymer upon heating. They can find particular use in producing water-soluble highly-branched hydrophilic polymeric material and in producing water gradient contact lenses.

    Abstract: A method of fabricating a device includes forming a dummy gate over a plurality of fins. Thereafter, a first portion of the dummy gate is removed to form a first trench that exposes a first hybrid fin and a first part of a second hybrid fin. The method further includes filling the first trench with a dielectric material disposed over the first hybrid fin and over the first part of the second hybrid fin. Thereafter, a second portion of the dummy gate is removed to form a second trench and the second trench is filled with a metal layer. The method further includes etching-back the metal layer, where a first plane defined by a first top surface of the metal layer is disposed beneath a second plane defined by a second top surface of a second part of the second hybrid fin after the etching-back the metal layer.
