Title: Method for detecting posture of article
Inventor: KITA YASUYO
IPC: G01B11/26
Filed: 1993-10-07
Abstract: PURPOSE:To establish a method for detecting a posture of an object not limiting a shape of the object, by obtaining an equation of motion of a representative point before the object moves when a force acts to the representative point in a field where the force corresponding to a distance of representative points before and after the object moves acts.

Therefore, the repulsive forces are equal in size and offset each other. When representative points of the initial posture and target posture are set in a field of a predetermined potential energy distribution based on the target posture of the rigid body and an equation of motion of the rigid body is obtained in the field, a changing amount of posture of the rigid body is detected before the initial position overlaps with the target posture.

Title: Manufacture of semiconductor integrated circuit device
Inventor: NAKADA TOSHIKAZU
IPC: H01L21/768
Filed: 1986-11-21
Abstract: PURPOSE:To flatten the stepped section of the surface of an silicon oxide film gently by irradiating the whole surface of the silicon oxide film, to which phosphorus is added, with excimer laser beams of a wavelength of 200nm or less and heating the whole surface of the silicon oxide film. CONSTITUTION:When heat treatment at a high temperature of approximately 1000 deg.C is executed, an inclination at the stepped section of a PSG film is made easy, but impurity atoms are further diffused and redistributed. When the PSG film 20 is irradiated with excimer laser beams 22 and heated as a method in which the impurity atoms are not redistributed, the PSG film 20 is made to reflorw, and the inclination of the stepped section is flattened gently. Since excimer laser beams 22 are absorbed to the PSG film 20, excimer laser beams 22 do not reach to a semiconductor substrate as the lower layer of the PSG film 20, and redistribution by the rediffusion of the impurity atoms is not generated, thus acquiring a semiconductor integrated circuit device having high reliability.
