Abstract
A resistor located above the semiconductive substrate of an integrated circuit chip can be made smaller than prior art resistors because no area is allocated for resistor contacts. During manufacture, a resistive strip having the width of the intended resistor is formed. A photoresist mask protects the top and sides of the resistive strip where the resistor is located, and etching exposes the ends but not the top and sides of the resistor. Contact to the resistor occurs at the upwardly extending (usually near vertical) end surfaces of the resistor.
