摘要： A basic sample having a surface is set in an ultrahigh vacuum chamber. Atoms constituting the sample are deposited on the surface of the sample to remove vacancy-type defects. A laser beam having a predetermined wavelength and a predetermined fluence is radiated on the sample to remove adatom-type and kink-type defects, thereby producing a defect-free surface. In addition, the same material as that for a basic sample is deposited on a defect-free surface to produce a defect-free thin film.

摘要： The ablation threshold of a laser fluence with respect to the surface of a sample manufactured in a high vacuum chamber is determined by using the sample. The quantity of vacancy-type defects is determined by radiating a laser beam having a fluence slightly higher than the ablation threshold on the surface. At the same time, the quantities of adatom-type and kink-type defects are determined by radiating a pulsed laser beam having a fluence slightly lower than the ablation threshold on the surface repeatedly to obtain the relation between an emission yield and the number of laser pulses. The quantity of the adatom-type defects is obtained by determining the area (total quantity of emitted atoms) of a rapidly decreasing portion of the relation. The quantity of kink-type defects is obtained by determining a magnitude of an emission yield of a slowly decreasing portion of the relation.

摘要： An exposure apparatus for selectively exposing the peripheral portion of a circular substrate such as wafer for integrated circuit manufacturing purposes. In this exposure apparatus, the spot of an exposure light beam from a projecting system is projected onto the peripheral portion of a resist-coated surface of a substantially circular substrate in such a manner that a part of the spot projects from the peripheral edge of the substrate. The portion of the spot projecting from the peripheral edge of the substrate is received by a detector arranged opposite to the projecting system through the intermediary of the substrate peripheral portion so that the position of the substrate peripheral edge in the projected spot is detected in accordance with the contour position of the received spot portion. During rotation of the substrate, in accordance with the detection signal the projecting system is controlled to move in the radial direction of the substrate in response to the displacement of the substrate peripheral edge so that the exposure light beam always illuminated the peripheral portion of the substrate within a given dimensional extend in the radial direction. Further, in the present exposure apparatus the rotational speed of the substrate and the exposure conditions by the spot formed on the substrate peripheral portion by the light beam (the intensity and/or size of the integrated exposure light) are controlled in such a manner that the exposure light quantity applied to the substrate peripheral portion by the spot attains a predetermined proper exposure light quantity.

摘要： Prior to a periphery exposing operation, a light emitting unit and a light receiving unit are retracted to a position separate from a wafer, and a calibrating operation is conducted in the retracted position utilizing a light shield plate different from the wafer to be exposed, thereby obtaining a servo control reference signal for the exposure. At the exposure of the periphery portion of the wafer, the exposure width is controlled according to the reference signal. It is therefore rendered possible to achieve exact peripheral exposure, including the intensity and intensity distribution of the exposing light beam immediately before the irradiation of the peripheral portion of the wafer.

摘要： A method and an apparatus for monitoring and fault-analyzing a network which includes a plurality of LANs. LAN-to-LAN connectors are provided between LANs. The apparatus includes a monitor fault analyzer. A terminal is connected to a LAN, to issue a command which stores specific packets or transfers stored packets, from a command transmitter to LAN-to-LAN connectors. Upon receiving a command, a command holder of a routing unit (router) of the LAN-to-LAN connector holds the command. The router carries out the usual routing process to pass or block packets transferred from the LAN interfaces according to the addressee. A unit for detecting and copying the specified packets compares the address of each received packet with the addresses stored in the command holder, and if they agree with each other, copies the packet. A data storage unit stores the copy in the storage unit and the time of reception of the packet is measured by the timer and added to the packet. The apparatus monitors and analyzes the contents and time of the collected packets having the addresses of the monitored terminals.
