Abstract
A method of constructing a multilayer electric apparatus. The method includes forming a set of conductive features and a plurality of fiducial markings on a first dielectric layer in mutual reference to each other so that their relative positions are known to a first tolerance. Also, a pattern of information corresponding to a desired photoresist exposure pattern for a second layer of the multilayer electric apparatus is stored in a computer readable format. The locations of the fiducial markings on the first layer are measured and the pattern of information for the second layer is altered in correspondence to the measured locations of the fiducial markings. The updated pattern of information is used to control a laser to selectively expose the photoresist on the second layer. Finally, the first and second layers are joined to each other.
