Abstract: In one aspect, the present invention is a technique of, and a system and sensor for measuring, inspecting, characterizing and/or evaluating optical lithographic equipment, methods, and/or materials used therewith, for example, photomasks. In one embodiment of this aspect of the invention, the system, sensor and technique measures, collects and/or detects an aerial image produced or generated by the interaction between the photomask and lithographic equipment. An image sensor unit may measure, collect, sense and/or detect the aerial image in situ—that is, the aerial image at the wafer plane produced, in part, by a product-type photomask (i.e., a wafer having integrated circuits formed during the integrated circuit fabrication process) and/or by associated lithographic equipment used, or to be used, to manufacture of integrated circuits.

Abstract: In one aspect, the present invention is a sensor unit for sensing process parameters of a process to manufacture an integrated circuit using integrated circuit processing equipment. In one embodiment, the sensor unit includes a substrate having a wafer-shaped profile and a first sensor, disposed on or in the substrate, to sample a first process parameter. The sensor unit of this embodiment also includes a second sensor, disposed on or in the substrate, to sample a second process parameter wherein the second process parameter is different from the first process parameter. In one embodiment, the sensor unit includes a first source, disposed on or in the substrate, wherein first source generates an interrogation signal and wherein the first sensor uses the interrogation signal from the first source to sample the first process parameter.

Abstract: A language instructional process is disclosed. The process includes identifying a word or sentence having sound that is difficult to pronounce or that is often confused. The process also includes training to hear the sound accurately, viewing mouth movement when making the sound, and pronouncing the word or sentence. The process further includes recording the mouth movement when pronouncing the word or sentence, sending a recording of the mouth movement to an instructor, and reviewing a feedback from the instructor.

Abstract: Systems, methods and computer program products detect a position of a new alignment mark on a substrate by producing an alignment signal model from sample alignment signals and fitting the new alignment signal to the alignment signal model. The alignment signal model may be produced from the multiple sample alignment signals using singular value decomposition, based on subspace decomposition of the alignment signals. By producing an alignment signal model from multiple sample alignment signals, asymmetries in the sample alignment marks and/or in the coatings that are fabricated on the sample alignment marks, may be taken into account when detecting the position of a new alignment mark.
