Abstract
In accordance with the present invention, trim pads used in trimming on-chip resistive elements are formed in the scribe channels interposed between respective dice on a wafer. Metal traces connect the trim pads to their associated resistive elements formed on the dice. Thus, each trim pad formed within the scribe channels results in a corresponding increase in the usable silicon surface area of the dice, thereby saving valuable silicon real estate.
