Abstract:
A method for producing electrode contacts for a semiconductor chip having a plurality of previously formed individual semiconductor integrated circuit elements secured to a substrate comprising the steps of:forming an insulating film on an interconnection pattern of a first integrated circuit element that has been secured to the substrate, forming on the insulating film a mask layer having an opening at a position where electrodes of the first semiconductor integrated circuit element are located, removing the insulating film within the opening by using the mask layer as a mask to expose a portion of the interconnection pattern, forming a conductor layer on the exposed interconnection pattern and the mask layer, removing the conductor layer formed on the mask layer while leaving the conductor layer formed on the exposed interconnection pattern, and removing the mask and further wherein the conductor formed on the exposed interconnection pattern forms an electrical connection to a second intergrated circuit element that is also secured to the substrate, electrical connection to the second integrated circuit element also being formed by patterning insulation formed on the second integrated circuit element while it is secured to the substrate.
