SOFT LITHOGRAPHIC STAMP WITH A CHEMICALLY PATTERNED SURFACE |
摘要 |
The present invention provides a soft lithographic stamp (30) and a method for the manufacturing of such a stamp (30). A stamp (30) according to the present invention comprises blocking regions (37) and printing regions (38). The blocking regions (37) are formed of a material which is different from the material the printing regions (38) are formed of and which exhibits a reduced permeability, diffusivity or absorbing or adsorbing capability to the printing compound, such that it prevents or significantly reduces chemical or physical transport or transfer of the printing compound from the blocking regions to a substrate that has to be patterned or printed. In that way, when impregnating the stamp (30) with a printing compound, the printing compound only diffuses into the printing regions (38) and hence, the printing compound is only transferred from the printing regions (38) to the substrate to be patterned and substantially no diffusion of printing compound via air voids (33) between protruding elements (32) will occur. ® KIPO & WIPO 2007
