Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
72 words
A micro-contact printing stamp comprising: a flexible layer having a first surface and a stamping surface opposing the first surface, the stamping surface defining a plurality of features having characteristic dimensions of less than 100 micrometers, the plurality of features defining a stamping pattern; and a support structure chemically bonded to the first surface of the flexible layer whereby the support structure reduces deformation of the stamping pattern of the stamping surface.
Claim 2
Dependent Claim
72 words
A micro-contact printing stamp comprising: a flexible layer having a first surface and a stamping surface opposing the first surface, the stamping surface defining a plurality of features having characteristic dimensions of less than 100 micrometers, the plurality of features defining a stamping pattern; and a support structure chemically bonded to the first surface of the flexible layer whereby the support structure reduces deformation of the stamping pattern of the stamping surface.
