Title: Method and apparatus for inspection as well as manufacture of semiconductor substrate
Inventor: SHIBATA YUKIHIRO
IPC: G01N21/956
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which an image can be detected with high resolution and in which a very small defect can be detected, by a method wherein the polarization of illumination light is controlled according to a pattern formed on an object to be inspected. SOLUTION: Illumination light is incident on a polarizing beam splitter 22 along an illumination optical axis 7. Out of it, an S-polarized component is reflected by the boundary face between a glass member 22a and a glass member 22b, and a P-polarized component is transmitted. Light by the transmitted P-polarized component is changed into oval polarized light. Light by the oval polarized light illuminates a sample 1 via an objective lens 30. Light which is reflected and refracted by the sample 1 is transmitted again through the objective lens 30 and a quarter-wave plate 401. When the light travels back and forth, a phase difference at 180 deg. is generated, and S-polarized light is generated mainly. As a result, the light which is incident on the beam splitter 22 again is reflected by the boundary face so as to be guided to a detecting system.  A detecting apparatus by this invention has a tendency that, the higher the contrast C of a circuit pattern is the more a very small defect can be detected. However, the apparatus has a demerit, either pattern is given priority according to an object to be inspected, and the angle of rotation θ of the quarter-wave plate 401 is controlled so as to be selected.

Title: Cell transfer equipment
Inventor: MATSUURA TAKEO
Filed: 1991-06-06
Abstract: PURPOSE:To transfer a cell with higher priority earlier than a cell with lower priority to an outgoing line at all times. CONSTITUTION:When a cell is inputted from incoming lines 1001-100m in the operation step 1, an incoming line module stores the cell to its internal priority depending buffer. The incoming line module storing a cell in its incoming side buffer makes a request of a cell transmission right to buses 21, 22 in the operation step 2. The incoming line module survived in the contention of the cell transmission right reads the cell from its internal incoming side buffer and sends the cell to a bus together with an outgoing line number of an output destination. Each outgoing line module selects and receives only the cell addressed to its own outgoing line from the bus and stores it to the outgoing buffer. The outgoing line module reads a cell from an outgoing side buffer and outputs the cell to an outgoing line in the operation step 3.
