Title: Surface inspection system
Inventor: SEKINE AKIHIKO
IPC: G01N21/88
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To inspect the entire surface of a wafer surely by performing surface inspection using an optical signal received in a part of reciprocal inspection range other than a transition area where an object is being scanned from the outside thereby eliminating a range which can not be inspected due to a scattering light from an edge. SOLUTION: A photoelectric converter at a light receiving section outputs a light receiving signal from the central part to the second half part of a wafer 1 during outward scan and a light receiving signal from the central part to the second half part of the wafer 1 during inward scan based on a synchronization signal and invalidates a light receiving signal in the area (transition area) from the outside to the central part of the wafer 1. Consequently, a scattering light data is not stored during the first half interval t0-t5 of outward scan and the first half interval t10-t15 of inward scan but the data during the second half interval t5-t10 of outward scan and the second half interval t15-t20 of inward scan is stored sequentially. Subsequently, the processing is repeated.  Since the data can be acquired surely over the entire surface of the wafer 1 except upper and lower small parts, the entire surface of the wafer can be inspected surely.

Title: Sampling clock generating circuit
Inventor: YANAGISAWA MASAYOSHI
IPC: H03M1/12
Filed: 1993-07-12
Abstract: PURPOSE:To obtain a sampling clock always proportional to (n) times the frequency of an input signal by connecting a high pass filter(HPF) for removing a DC component to a signal input part in a sampling clock generating circuit. CONSTITUTION:When an input signal to which positive DC voltage e.g. is superposed is applied to the HPF 2a and a waveform obtained by removing a DC voltage component is outputted. The output of the HPF 2a is applied to a succeeding low pass filter(LPF) 2 to remove a noise component and the original waveform of the input signal is restored and applied to a waveform shaping circuit 3. The circuit shapes the waveform of the signal applied from the LPF 2 to a square wave with 50% duty ratio by a zero-crossing comparator and outputs the shaped signal to a PLL circuit 4. The PLL circuit 4 compares the phase of the square wave signal applied from the shaping circuit 3 with that of a signal obtained by dividing oscillation frequency from an internal oscillator into 1/n frequency and controls oscillation frequency so that the phase of the 1/n frequency demultiplied signal is synchronized with that of the square wave signal.
