Abstract:
A method for selecting charge transport and/or anti-quenching materials is presented. The method includes determining a first luminescence intensity I0 of a luminescent material in the absence of the charge transport and/or anti-quenching material, determining a second luminescence intensity Iq of the luminescent material in the presence of the charge transport and/or anti-quenching material, and comparing the first luminescence intensity I0 with the second luminescence intensity Iq to determine a luminescence quenching constant of the charge transport and/or anti-quenching material with respect to the luminescent material. A device made using charge transport and/or anti-quenching material selected using the selection method and a kit to practice the selection method.
Abstract:
Disclosed are apparatus and methods for characterizing a potential defect of a semiconductor structure. A charged particle beam is scanned over a structure which has a potential defect. X-rays are detected from the scanned structure. The X-rays are in response to the charged particle beam being scanned over the structure. The potential defect of the scanned structure is characterized based on the detected X-rays. For example, it may be determined whether a potentially defective via has a SiO2 plug defect by comparing an X-ray count ratio of oxygen over silicon of the defective via with an X-ray count ratio of a known defect-free reference via. If the defective via has a relatively high ratio (more oxygen than silicon) as compared to the reference via, then it may be determined that a SiO2 plug defect is present within the defective via. Otherwise, the via may be defmed as having a different type of defect (e.g., not a SiO2 plug defect) or defined resulting in a “false” defect. Accordingly, specific embodiments of the present invention may be utilized to filter “false” defects from a defect sample.

Abstract:
The present invention is directed to a system and method for designing efficient multi-channel FBG gratings using a pre-compensated phase mask for diffracting light for side-writing the grating on an optical fiber core. A desired phase function of the FBG is generated, specifically tailored to an effective spacing between the phase mask and the optical fiber core. From the phase function a phase mask is pre-compensated to offset diffraction effects associated with each longitudinal position of the FBG receiving light from two corresponding longitudinal positions of the phase mask substantially symmetrically spaced longitudinally relative to each particular longitudinal position of the FBG. The two corresponding longitudinal positions of the phase mask are spaced longitudinally from each other by a spacing determined by the effective spacing between the phase mask and fiber core and by the first order diffraction angle of light through the phase mask.
Abstract:
This invention discloses an improved address table apparatus that includes an address bus for receiving input data packets and for hashing a designated bucket number and extracting a key from each of the data packets. The address table apparatus further includes a plurality of memory banks connected to the address bus wherein each memory bank includes a plurality of memory buckets for storing a designation address (DA) and a port number in each of the buckets. The address table apparatus further includes a comparand bus connected to the address bus for receiving the key therefrom. The address table apparatus further includes a plurality of comparators each corresponding to one of the memory banks for receiving the designation address (DA) and the port number from the designated bucket from a corresponding memory bank. The comparators further connected to the comparand bus for receiving and comparing the key to the address from the designated bucket in each of the memory banks. The address table apparatus further includes a result bus connected to the comparators for displaying an output port number from one of the comparators if the key extracted from one the data packets matching the designation address (DA) from one of the designated buckets.
