Patent number: 6403973Abstract: The present invention provides an electron beam exposure method and an exposure apparatus suitable for use in the electron beam exposure technology for performing exposure on a sample placed on a sample table by an electron beam while continuously moving the sample table, both of which are capable of performing high-accuracy and high-speed exposure without being affected by glitch noise of a DA converter used for trace deflection of the electron beam. Displacements of the position of the sample table and the position to apply the electron beam are determined and the determined displacements are divided into the amount of a shot synchronous trace and the amount of a real time trace each synchronized with shot timing for applying the electron beam to thereby reduce the amount of the real time trace, whereby degradation in exposure accuracy due to the glitch noise of the DA converter used for trace deflection is prevented from occurring. It is therefore possible to carry out high-accuracy exposure.Type: GrantFiled: February 7, 2000Date of Patent: June 11, 2002Assignee: Hitachi, Ltd.Inventors: Hiroyuki Takahashi, Masahide Okumura, Koji Nagata, Kimiaki Ando

Patent number: 6159644Abstract: In a semiconductor circuit device fabricating process in which a reduction image projection exposure apparatus and an electron beam exposure apparatus are in a mixed use in its exposure process, pattern position shift errors for each exposure apparatus are measured and corrected at the time of drawing by means of an electron beam drawing apparatus, thereby enhancing the alignment accuracy.First, a pattern for measuring position shifts is exposed using a stepper and the electron beam drawing apparatus. Then, the position shift errors are measured using an identical coordinate position measuring device. Accidental errors have been mixed in the measurement result at this time. On account of this, measurement data at a certain point are smoothed by taking a summation average with data on the periphery thereof, thus decreasing influences of the accidental errors. Moreover, by inverting positive or negative signs of the data on the position shift errors, the data are made into correction data.Type: GrantFiled: September 1, 1998Date of Patent: December 12, 2000Assignee: Hitachi, Ltd.Inventors: Hidetoshi Satoh, Yoshinori Nakayama, Masahide Okumura, Hiroya Ohta, Norio Saitou

Patent number: 5650631Abstract: A blanking array is used for controlling an electron beam in an electron beam writing system. Electrodes in the array are formed in parallel and two sets of the parallel electrodes, orthogonal to one another, are used for dividing the electron beam into a plurality of individual exposure areas. The sets of parallel electrodes can be formed in one array by a wire mesh or in two separate arrays spaced closely together or farther apart at different focal point positions. The electrodes are provided to extend across an aperture, such as a square or triangular aperture. For a triangular aperture, the electrodes are made parallel to the hypotenuse of the triangle. The writing patterns are formed by combining the exposure areas. Control of each exposure area is realized by applying opposite polarity voltage to adjacent electrodes in order to deflect the portion of the beam passing between the adjacent electrodes.Type: GrantFiled: June 7, 1995Date of Patent: July 22, 1997Assignee: Hitachi, Ltd.Inventors: Yasunari Sohda, Masahide Okumura, Yasuhiro Someda, Hidetoshi Satoh, Yoshinori Nakayama, Norio Saitou
