Publication number: 20090280239Abstract: First, a catalyst for performing electroless plating in a subsequent step is caused to adhere to surfaces of uneven portions of a matrix. Next, an insulating layer made of a resin material is prepared. Then, the insulating layer is heated to be softened while the uneven portions of the matrix are pressed against one surface of the insulating layer. Thus, grooves corresponding to shapes of the uneven portions of the matrix are formed in the insulating layer while the catalyst is transferred to bottom surfaces and side surfaces of the grooves. The insulating layer is then subjected to electroless plating. In this case, metal is deposited by reduction reaction on portions of the insulating layer where the catalyst exists. Accordingly, conductor traces are formed in the grooves of the insulating layer.Type: ApplicationFiled: April 17, 2009Publication date: November 12, 2009Applicant: NITTO DENKO CORPORATIONInventors: Shigenori MORITA, Takashi ODA, Naoko YOSHIDA
