Abstract
Abstract A substrate has two or more conductive layers deposited thereon, each adjnt layer pair separated by a dielectric layer. Apertures are formed in the dielectric layer and are filled with resistor paste. In this way, a resistive path may be formed between the conductive layers. This concept of fabricating resistors are particularly useful in the inclusion of pull-up, pull-down and other non-critical resistors in the circuitry contained within a thick film construction.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
115 words
In a multi-layer circuit structure having first and second layers separated by a non-conducting layer, the improvement comprising, a first conductor portion associated with said first layer and a second conductor portion associated with said second layer, an aperture means formed in said non-conducting layer, and resistive material located in said aperture means, said first and second conductor portions being positioned adjacent opposite portions of said resistive material and partially overlapping opposite portions of said aperture means, whereby an electrically conductive path is established between said first and second conductor portions, and the resistance of said path is dependent upon the extent of overlap of said conductor portions with said aperture means and resistive material.
