Patterning method of cadmium sulfide thin film by combining microcontact printing method and selective chemical solution deposition

摘要

The present invention combines selective contact with chemical contact deposition and fine contact printing that can be patterned by depositing an organic thin film onto a substrate using polymer coating and depositing cadmium sulfide thin films on surfaces without organic thin films using chemical solution deposition. A method of forming cadmium sulfide and various monolayer thin films, the method comprising: forming a mold (4) having irregularities on the first substrate (2) using lithography, and forming a pattern mold (4) formed on the substrate (2). To polymerize the polymer polydimethylsiloxane (PDMS) on the upper side to form a polymer elastomer coating (6) and to coat the polymer elastomer coating (14) with an organic compound ink (14) on the second substrate (8). Forming a coating film 10 by using microcontact printing, and between the coating film 10 formed on the substrate 8, a cadmium sulfide monolayer 12 is formed by chemical solution deposition. There is a characteristic consisting of the step of forming.
