Abstract
A method and an apparatus for manufacturing a device are provided. The method and the apparatus can form micro wiring without undesired wetting and spreading using an inexpensive functional-liquid supplying method. A method for forming a device, such as a radiofrequency identification tag, includes: making patterns at a plurality of sections having different degrees of affinity to the functional liquid on a substrate to form the device; and supplying the functional liquid to the selected section having high affinity to the functional liquid. Forming the plurality of sections having different degrees of affinity to the functional liquid includes, for example: supplying an organosiloxane film on the substrate, and exposing the organosiloxane film through an optical mask.
