Antireflective coatings for high-resolution photolithographic synthesis of DNA array

摘要

The present invention provides an array of polymers and methods of forming arrays of polymers by providing a substrate having a first layer including one or more dielectric coatings on a solid support and a second layer including a plurality of polymers disposed on the first layer. The invention also provides methods for forming an array of polymers on a substrate using light-directed synthesis by providing a substrate having a first layer including one or more dielectric coatings on a solid support; derivatizing the first layer by contacting the first layer with a silanation reagent, and a second layer disposed on said first layer wherein the second layer includes functional groups protected with a photolabile protecting group.
