Title: Chip supplying device from wafer in bonder
Inventor: TERADA TORU
IPC: H01L21/68
Filed: 1992-11-30
Abstract: PURPOSE:To make the rotation center of chips and those of a thrusting-up pin and the attraction head of a pick-and-place unit coincide, and to facilitate the control of chip feeding to a bonding stage, by causing the thrusting-up pin and the suction head to have THETA drive mechanisms respectively. CONSTITUTION:A stage 10 in an expanding part 2 has X- and Y-direction drive mechanisms, and a thrusting-up pin which acts on chips from under a wafer has a THETA drive mechanism for correcting the angle of rotation of the pin. Besides, the suction head of a pick-and-place unit 3 has a THETA drive mechanism for correcting the angles of rotation of the chips. For example, a picture processing camera detects the angle of rotation of each chip, and adjusts the angle of the thrusting-up pin by controlling the THETA drive motor. In addition, the shear angle of the chip is corrected by the THETA drive of the suction head of the pick-and place unit 3, and the chip is delivered to a bonding stage 32.

IPC: G02B27/64
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To stabilize an image to be observed and a visual field area with respect to the line of sight of an observer by displacing a field diaphragm provided in the vicinity of the real image surface in a telescope optical system at the same time when an image deflecting means stabilizes the image. SOLUTION: Even though the telescope optical system is vibrated by hand shake and the image to be observed is displaced, a variable apex angle prism 5 as the image deflecting means deflects a luminous flux from an object so as to compensate the displacement, so that the stabilized image can be observed. The field diaphragm 4 is displaced so as to keep the visual field observed before the telescope is shaken by the shake at the same time when the prism 5 deflects the luminous flux from the object. Thus, the stable image can be observed with the stable visual field. Besides, the shake of the diaphragm 4 is corrected, so that the image which is always stable with respect to the line of sight of the observer and the visual field area in which the vignetting of the image by means of the diaphragm 4 does not exist can be obtained.
