Abstract: A thin-film metal resistor (44) suitable for a multilayer printed circuit board (12), and a method for its fabrication. The resistor (44) generally has a multilayer construction, with the individual layers (34, 38) of the resistor (44) being self-aligned with each other so that a negative mutual inductance is produced that very nearly cancels out the self-inductance of each resistor layer (34, 38). As a result, the resistor (44) has a very low net parasitic inductance. In addition, the multilayer construction of the resistor (44) reduces the area of the circuit board (12) required to accommodate the resistor (44), and as a result reduces the problem of parasitic interactions with other circuit elements on other layers of the circuit board (12).

Abstract: An apparatus and method are disclosed for sensing horizontally and measuring the level or tilt of features on different locations on a wafer in general, and on chip sites, in particular. This is accomplished on a conventional level sensor, modified and improved, however, according to this invention where a new electrically adjustable, two-directional zoom lens is introduced. The adjustable zoom lens provides field-by-field alignment on a stepper, by providing a variable field view and depth of focus on the viewed field. Thus, whereas prior art provides fixed field-by-field local alignment capability over fixed ship sites on a ware, the present invention extend that capability to variable field-by-field alignment over variable sites on a wafer.
