A method and system for providing three-dimensional preview of a finished document based on a key feature analysis. In order to make it possible, by simple means, to shorten the time until service-readiness carrying elements adjusted in respect of the spacing b relative to the roller are utilized for adjustment of the biasing device. After implanting one or more impurity materials to the source and drain regions, and the transistor goes through an annealing process using a high speed heat source other than a Tungsten-Halogen lamp.
