Abstract:
1. A method for manufacturing a circuit board from an intermediate product having an insulator layer and at least one component at least substantially inside the insulator layer, the at least one component comprising semiconductor material and contact elements in electrical contact with the semiconductor material, the intermediate product comprising a support membrane covering the contact, the method comprising: removing the support membrane and revealing the contact elements facing towards the support membrane, individually cleaning the surfaces of the contact elements by means of a laser for the creation of electrical contacts, manufacturing a conductor-pattern layer on the surface of the insulator by growing the conductor-pattern layer directly in a correct shape by a growing method, in such a way that the conducting material of the conductor-pattern layer connects electrically to the contact elements of the component and the conductor-pattern layer has the correct shape, simultaneously, with the manufacturing of the conductor-pattern layer, manufacturing a second conductor-pattern layer on the opposite side of the insulator layer, and continuing manufacturing of the circuit board by making a number of alternating insulator layers and conductor-pattern layers on top of the conductor-pattern layers.
