    摘要: A photomask for use in manufacturing a semiconductor includes a chrome pattern serving as a mask pattern. The chrome pattern is formed so as to have a size substantially equivalent to a wavelength of an exposure light at an interval substantially equivalent to the wavelength. The chrome pattern includes a band-shaped first chrome pattern and a second chrome pattern having a side in the widthwise direction substantially orthogonal to the side in the lengthwise direction of the first chrome pattern. Then, auxiliary patterns of a size of not more than the wavelength of the exposure light, which have a function of reducing the exposure light or shifting the phase of the exposure light, are formed at both corners of the side of the second chrome pattern so as to partially overlap the second chrome pattern. When forming a resist pattern of a size substantially equivalent to the wavelength of the exposure light or a resist pattern at an interval substantially equivalent to the wavelength of the exposure light, the described photomask suppresses the backward shift of the corner of the first resist pattern corresponding to the auxiliary patterns as well as the deformation of the second resist pattern positioned apart from the corner by a distance substantially equivalent to the wavelength of the exposure light.

    摘要: Sub-micron features are defined photo-lithographically by combining phase-shifting techniques with conventional photo lithographic techniques. In a first step, phase-shifting edges are defined in a photoresist layer. Dark-bands develop at the phase-shifting edges due to wavefront interference of an illuminating radiation in a subsequent exposure step. Development leaves behind sub-micron sections of photoresist which were covered by the dark-band regions. The dark-band sections are hardened and overcoated with a new layer of photoresist. A second pattern is projected onto the second layer of photoresist using conventional techniques. The second pattern is developed so as to create features having dimensions reduced by parts of the dark-band sections previously developed.

    摘要: A sensor having a pair of sensor units, one of which is a detecting sensor unit and the other of which is a reference sensor unit, wherein each of the units comprises a substrate with a hollow portion, a thin insulating layer with a bridge, cantilever or diaphragm shape disposed on the substrate, a sensitive film disposed on the bridge, cantilever or diaphragm portion of the thin insulating layer, and a pair of electrodes being in contact with the sensitive film, the sensitive film section of the detecting sensor unit being exposed to an atmosphere to be measured so that the electrical resistance of the sensitive film changes with a variation in the physical quantity of the atmosphere to be detected, and the sensitive film section of the reference sensor unit being sealed within a shielding container so that the electrical resistance of the sensitive film is not influenced by a variation in the physical quantity of the atmosphere outside of the container, whereby the absolute physical quantity of the atmosphere to be detected is determined by the output power of the sensor based on a difference between the electrical resistance of the detecting sensor unit and the electrical resistance of the reference sensor unit.
