Method for embedding a component in a base and forming a contact

The publication claimed is a method, wherein a form a part of electronic transistor unit or at least multiple transistor unit terminal of the process of manufacturing a base and a base according to a circuit board. Thus, a structure is around the semiconductor device manufacturing or more not. To the invention, a transistor unit at least one conductive pattern and feeds is first line of the base. For semiconductor element arranged on the hole, aims at the conductive pattern. The transistor unit is connected with the base, and one or multiple conductive pattern layer and a base, so that the number of causing at least one conductive pattern and transistor unit of contact area of the electric contact.
