    摘要: A method for matching a first OPE curve (700) for a first exposure apparatus (10A) used to transfer an image to a wafer (28) to a second OPE curve (702) of a second exposure apparatus (10B). The method can include the step of adjusting a tilt of a wafer stage (50) that retains the wafer to adjust the first OPE curve. As provided herein, the first exposure apparatus (10A) has the first OPE curve (700) because of the design of the components used in the first exposure apparatus (10A), and the second exposure apparatus (10B) has a second OPE curve (702) because of the design of the components used in the second exposure apparatus (10B). Further, the tilt of the wafer stage (50) can be selectively adjusted until the first OPE curve (700) approximately matches the second OPE curve (702). With this design, the two exposure apparatuses (10A) (10B) can be used for the same lithographic process. Stated in another fashion, exposure apparatuses (10A) (10B) from different manufacturers, when using the same reticle (26), will transfer similar images to the wafer (28).

    摘要: A test mark, as well as methods for forming and using the test mark to facilitate the measurement of the critical dimensions of etched features in semiconductor and other wafer level processing is described. The test marks may be used to characterize, calibrate and/or monitor etch performance. Test marks are defined by imaging (typically at partial exposures) overlapping, angularly offset lines in a resist that covers a layer to be etched. The lines preferably have line widths that are equal (or related) to a critical dimension of interest. After the resist is developed and otherwise processed, the layer is etched as appropriate, thereby creating the test marks. The test marks are then imaged to facilitate the determination of a geometric parameter of each mark. Most commonly, the geometric parameter determined relates to the area of the mark and/or the length of its major dimension. These parameters can then be used to approximate a critical dimension of interest based at least in part on the determined geometric parameter of the test mark.

    摘要: A dual guide beam stage mechanism for accurate X-Y positioning for use e.g. in semiconductor processing equipment provides accurate planar motion and yaw control. Over-constraint between components in their relative motion is minimized by utilizing flexibly mounted air bearings at the connection between at least one of the moveable guide beams and its corresponding stationary guide, and between at least one of the guide beams and the adjacent stage itself. Thus stage yaw motion is provided by allowing yaw motion of one of the guide beams. Preloading provides enough constraint through the air bearings without over-constraining the moving components, thereby improving accuracy and also reducing the need for close manufacturing tolerances.
