Title: Method and apparatus for exposing wafer periphery
Inventor: MIMURA YOSHIKI
IPC: G03F7/20
Filed: 2001-12-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and apparatus for exposing wafer periphery, which enables exposure without permitting an exposure region at a notch portion to cut into the inside of a wafer.  <P>SOLUTION: The wafer is mounted on wafer transfer pins 3 to have the peripheral location of the wafer detected by wafer periphery detecting sensors 4. Assuming that the wafer has a complete circular form, a control unit 20 obtains the center position of the wafer on the basis of the detected peripheral location data. Then the eccentricity between the center of wafer and the center of rotation of a rotary stage 1 is obtained. In accordance with the obtained data, the rotary stage 1 is moved, so that the center of wafer and the center of rotation of the rotary stage 1 coincide with each other. The wafer transfer pins 3 are then descended to mount the wafer on the rotary stage 1. In this state, the rotary stage 1 is rotated, followed by irradiating the wafer periphery with exposure beams of predetermined width for exposure of the wafer periphery. Since the wafer rotates in a state where there is no eccentricity, the wafer periphery can be exposed with a given width.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To establish a signal level even for a period in which a bus line is not driven.  <P>SOLUTION: A level stability signal generator 2 drives a control line 32 for a sufficiently short period from a period of a clock TxClk synchronously with a rise of a clock TxClk immediately after a period in which an ATM device 14 outputs address data TxAddr for identifying a PHY device, is finished and outputs a level stability signal TxLSS of a low level to the control line 32.

Accordingly, a problem in which a signal waveform of the line 32 is gradually changed by drawing a slope during a period in which the line 32 is not driven by the PHY device, does not occur. A receiver 30 for a backboard can identify the cell available signal TxClav without mistake.  <P>COPYRIGHT: (C)2003,JPO
