    摘要: Apparatus and method for inhibiting the image of a transparent, undesired feature on a reticle from printing on semiconductor material. The apparatus includes a frame attachment connected to a pellicle frame that is attached to a reticle. A blade that is opaque to ultraviolet light is moveable across the frame attachment and may be positioned proximate the undesired feature of the reticle to prevent the printing of the image of the undesired feature on the semiconductor material. The blade may be positioned above the undesired feature to inhibit ultraviolet light from an illumination source from impinging upon the undesired feature. Alternatively, the blade may be positioned below the undesired feature to inhibit ultraviolet light passing through the undesired feature from impinging upon the semiconductor material.

    摘要: A Visual Basic software program to automate the procedures required for energy dose verification and adjustment of the ASM photoaligner. The software program has the capability of manipulating the ASM photoaligner through a resident software routine of the photoaligner. In addition, the software program has a user interface which prompts the operator for inputs and instructs the operator on what is required to perform the energy dose calibration. This ensures a reproducible procedure regardless of the photoaligner being tested or the operator doing the testing. Automating this procedure allows changing the photoaligner energy dose through the ASM Machine Constants (values stored in the ASM photoaligner that control the operation of the photoaligner). If the input data is out of specification the program will either reference a trouble shooting guide or request that the specific procedure be repeated for verification. After collecting the data from the operator, the program makes the necessary calculations and compares the results to a predefined data base which contains the specification limits for each of the individual photoaligners. Besides saving time, automating these procedures ensures that all operators perform them the same way, thereby eliminating operator-to-operator variation. Furthermore, it will no longer be necessary to open the ASM electronics cabinet to adjust the shutter control board potentiometer for brining the dose back to specification and by making the changes through software it will be possible to track them over time.
