Then a procedure named microcontact printing was carried out on the glass substrate with the ink of an octadecylsiloxane(OTS) solution. The OTS reacted with the glass and formed a self\|assembly monolayer, and the process produced hydrophobic micro\|patterns on hydrophilic substrate. Owing to a simple hydrophobic interaction between the CuSO\-4 solution and the monolayer, a regular CuSO\-4 micro\|crystal lattice could be produced.展开更多

These patterned polymer films can serve as resists in the argon ion etching effectively to transfer patterns into the underlying gold substrates. This method is flexible in controlling the shape and feature size of the patterns in the polymer resists by simply adjusting the concentration of polymer solution, and especially it also provides a route to sub-micrometer sized features by using an original template with micrometer sized features.展开更多
