Title: Aligner with reflective mask
Inventor: NIIBE MASATO
IPC: H01L21/027
Filed: 1987-12-29
Abstract: PURPOSE:To obtain a highly accurate aligner which can correct the optical performance, especially the picture image warpage, of a projection optical system satisfactorily and can perform satisfactory projection exposure of a pattern over a wide area by composing the substrate surface of a reflective mask of a curved surface. CONSTITUTION:X rays or vacuum ultraviolet rays are applied to the surface of a reflective mask MS and a pattern on the reflective mask MS is formed on a required surface W through optical systems M1-M3. In this constitution, the substrate surface of the reflective mask MS is composed of a curved surface. For instance, the pattern on the reflective mask MS is contracted and projected onto the surface of the wafer W by a reflective projection optical system composed of a concave mirror M1, a convex mirror M2 and a concave mirror M3. Generally speaking, if a projected area is enlarged in a reflective projection optical system, the optical performance is degraded by the influence of the image surface warpage. Therefore, by composing the substrate surface of the reflective mask MS of a curved surface such as a spherical surface, nonspherical surface or rotational asymmetrical surface, the image surface warpage created when the projected area is enlarged is corrected so that satisfactory optical characteristics can be obtained over the whole picture surface.

Filed: 1990-11-29
Abstract: PURPOSE:To perform de-emphasis processing on an analog signal after digital/ analog conversion selectively by providing a subtraction means which subtracts a signal equivalent to gain change to be extracted by an extraction means from an inputted analog signal. CONSTITUTION:This circuit is comprised of a de-emphasis circuit 200, a low-pass filter 210, a low-pass filter 220, and a system 400, etc. The signal equivalent to the gain change generated in an original analog signal is subtracted from the inputted analog signal by applying pre-emphasis processing. Therefore, the gain of the output signal of the subtraction means with respect to an arbitrary frequency component included in the inputted analog signal coincides with that of the original analog signal before applying the pre-emphasis processing. In other words, the output signal of the subtraction means is provided with the same frequency characteristic as that of the original analog signal. In such a way, it is not required to switch connection relation between circuit elements in the de-emphasis circuit corresponding to an input signal.
