Methods for designing and tuning one or more packaged integrated circuits
A method for producing and tuning a packaged integrated circuit a) incorporates into a packaged integrated circuit design, at least one tunable circuit feature; b) fabricates a packaged integrated circuit in accordance with said packaged integrated circuit design; c) identifies a trimming point on the tunable circuit feature of said packaged integrated circuit, using an x-ray inspection system; d) relates coordinates of the trimming point to coordinates of a visible reference marker; e) utilizes the relationship between the visible reference marker and the trimming point to position a cutting tool over the trimming point; and f) utilizes the cutting tool to make one or more cuts into the packaged integrated circuit, until the tunable circuit feature has been acceptably modified at the trimming point.
