Patent EP-0816798-A2 (EP)
Inventor: BOCKMAN JOHN J
IPC: G01B9/02
Filed: 1997-07-03
Abstract: In the claimed invention for an improved AC type interferometric metrology
apparatus, a change in position of an item disposed in a rotating reference frame is
measured. The rotating reference frame accumulates a rotation angle over a time period
with respect to a fixed reference frame. A quarter wave plate and an interferometer
comprising a polarizing beam splitter, a reference path reflector, and a measurement path
reflector are all mounted in the rotating reference frame. The measurement path reflector
is mounted to item so that changes in its radial position along an axis orthogonal to the axis
of rotation of the rotating reference system are measurable. In one preferred embodiment,
the components in the fixed reference frame are a two-frequency laser light source, a
stationary quarter wave plate, a receiver, for producing a measure signal containing
information representing the change in optical path length between the measurement and
reference paths of the rotating interferometer, the difference in the two frequencies of the
beams from the laser source, and the rotation angle, and a signal processor. The signal
processor receives the measure signal, a reference signal representing the difference
frequency of the laser light source, and a signal from a rotary encoder containing
information proportional to the rotation angle. The signal processor produces a signal
representing the measurement of the change in position. In another embodiment, the
rotary encoder is replaced by added optical components which automatically produce
optical signals that contain information about the rotation angle and the difference in the
two frequencies of the beams from the laser source.

Abstract: A particle sensor for a semiconductor device fabrication tool scans a laser
beam through a measurement volume immediately adjacent a wafer during
processing and detects light scattered by particles adjacent the wafer. Scanning
provides a real-time count of particles without interfering with processing.
Detected light can be forward-scattered, side-scattered, or back-scattered
depending on available optical access for a detector portion of the sensor. A pulse
in the intensity of scattered light results each time a particle is scanned. Because
the scanning velocity is high relative to the particle velocity, each particle may be
scanned several times while the particle is in the measurement volume. Analysis
fits a series of pulses observed for a single particle to a Gaussian distribution to
determine a size, position, and velocity for each particle and a time-resolved
particle count of the particles. The detected positions of particles are stored for
targeting subsequent surface scans of wafers to detect defects.

Abstract: Protective working gloves are manufactured from separate pieces that are joined together by stitching. The manufacturing process requires a seam at the level of the thumb-index finger junction, with this being the weakest point of the glove and statistically the first cause of tearing. 
The reinforcement is designed to provide over-protection to the glove in the anatomical area of the hand which, as a result of its maximum functional capacity, has the greatest bio-mechanical requirements: the thumb-index finger pincer is the common denominator of all activities involving catching, friction and pulling, with the seams suffering the greater wear and tear. This protection extends the useful life of the glove and increases the safety of the user. 
The reinforcement of the thumb-index finger junction is made of a sheet of the same material as that used in the glove or of another, more resistant, material, superimposed at the junction. 
The fastening procedures will vary according to the working glove and the material from which the reinforcing sheet is made.

Abstract: An object of this invention is to provide an adaptive
filter capable of reducing a convergence time and residual
error even when there exists an interval having a small input
signal power for a long time, and an adapting method thereof.
The adaptive filter comprises a signal power monitoring
circuit for receiving an input signal and outputs of delay
elements and outputting a first stop signal for stopping tap
position control and a second stop signal for stopping
coefficient updating and a coefficient updating control
circuit for receiving the second stop signal and an error
signal outputted by a subtracter and outputting the error
signal or zero to coefficient generating circuits as an
updating signal. The signal power monitoring circuit
calculates a sum of powers of all or part of signals of the
delay elements, so that if the power sum is smaller than a
first threshold, it turns on the first stop signal to stop
the tap position control and if the sum is smaller than a
second threshold, turns on the second signal to stop the
coefficient updating.
