  • Patent number: 5736300
    Abstract: One object of the present invention is to provide the reduced projection exposure method which enables the exposure of various and fine patterns in manufacturing process of semiconductor devices or semiconductor integrated circuit devices. Structure of the present invention to attain the above object is to carry out the reduced projection exposure using a phase shift mask provided with a prescribed correction pattern on the end of the mask pattern domain of a constant mode or the boundary of the mask pattern domain of plural modes. According to this structure, as the end effects etc. are canceled by the correction pattern, the various and fine patterns can be exposed.

  • Patent number: 5725971
    Abstract: A technique to minimize an increase in the design and manufacture times required for making phase shift masks is provided. The process of the technique involves preparing a hole unit cell comprising one target hole and auxiliary holes located close to the four sides of the target hole, and then laying out on first layout data first hole unit cells 26c.sub.1 -26c.sub.3 arranged in a certain orientation at a first pitch and second hole unit cells 27c.sub.1 -27c.sub.3 arranged in the same orientation at a second pitch, narrower than the first pitch. This process generates data of hole groups, each comprising the target hole and auxiliary holes on a first phase shift mask that is used in forming hole patterns in a resist film coated over the semiconductor substrate.

  • Patent number: 5405810
    Abstract: The present invention enables the accuracy of aligning a wafer and a reticle with each other in the exposure step in the manufacture of a semiconductor integrated circuit device to be improved. The portions of a metal film 5 and a resist film 6 which cover an alignment mark 4 on a wafer 1 are removed by a gas assisted etching treatment using a laser beam prior to the execution of an exposure treatment, so as to bare the alignment mark 4. The position detecting light is then applied from an alignment mark position detecting means in a reduction projection exposure unit 11 to the alignment mark 4, the position of the alignment mark 4 being detected on the basis of the light reflected on and scattered from the alignment mark 4.
