Claim 11:
12. A method, comprising:
forming an imprinting apparatus by:
depositing a formulation on a silicon master including a plurality of features positioned at an average pitch of less than about 425 nm, each of the plurality of features having a largest opening dimension of less than about 300 nm, and the formulation including:
a first silane monomer:, and
a second silane monomer including a hydrolyzable chloride group, the second silane monomer being present in an amount ranging from about 0.001 wt % to less than about 1.4 wt % based on a total weight of silanes present in the formulation; and

curing the formulation, thereby forming an anti-stick layer on the silicon master;

depositing a silicon-based working stamp material on the anti-stick layer of the imprinting apparatus;
curing the silicon-based working stamp material to form a working stamp including a negative replica of the plurality of features; and
releasing the working stamp from the imprinting apparatus.
