Patent ID: 7326643

Claim:
A method of making a circuitized substrate comprising: providing a first layer of organic dielectric material; forming a first electrically conductive circuit on said first layer of organic dielectric material including a first part with a plurality of lines of a first width and a second part of a highly dense pattern of substantially parallel lines each of a second width less than said first width; positioning a second, thin layer of organic polymer material including opposing ends on said second part of said first electrically conductive circuit; forming a second electrically conductive circuit on said second, thin layer of organic polymer material including a highly dense pattern of substantially parallel lines of substantially the same width as said second width of said substantially parallel lines of said second part of said first electrically conductive circuit; extending said substantially parallel lines of said second electrically conductive circuit down the sides of said opposing ends of said second thin layer of organic polymer material and onto said first layer of organic dielectric material, said second part of said first electrically conductive circuit, said second, thin layer of organic polymer material and said second electrically conductive circuit forming at least part of an organic memory device.
