摘要:
Methods and apparatuses for the analysis and detection of nanoparticles in a liquid from a semiconductor manufacturing component are provided herein. In some embodiments, a method of determining particle count, particle size, and zeta potential of nanoparticles in a substrate processing chamber component cleaning solution, includes (a) filling a sample cell with a cleaning solution from a substrate processing chamber component cleaning tank holding a semiconductor processing chamber component; (b) directing a light from a laser to the sample cell, wherein nanoparticles within the cleaning solution scatter the light from the laser; and (c) detecting the scattered light via one or more detectors proximate the sample cell to determine the zeta potential, the particle size and particle count of nanoparticles in the cleaning solution.

摘要:
Non-uniformities in substrate thickness and surface topography contribute significantly to the need for auto-focusing on a sample deposited thereon. These auto- focusing needs can be reduced or eliminated by measuring and storing substrate surface topography for later retrieval by an imaging system that can use the topographic information to help set appropriate focal parameters. These steps can be done in advance of an imaging experiment to reduce focus-related delays during the experiment. Topographic information can be stored, for example, in a database, associated with a representation of a unique substrate identifier; entry of the representation retrieves the topographic information. As another example, topographic information can be stored in an encoding device associated with the substrate.

A nanofluidic biosensor system (200) comprising a bottom substrate (120) and a top substrate (110) between which are defined an input lateral aperture (210), a nanoslit (230) which contains at least one functionalized area (231) and an output lateral aperture (220) or an internal reservoir (221), said biosensor system (200) being adapted to let a solution containing biomolecules (320) enter the input lateral aperture (210) and successively pass through said nanoslit (230) and said output lateral aperture (220) or internal reservoir (221); said biosensor system (200) furthermore comprising a gas evacuation subsystem (150-155) which is located between said nanoslit (230) and the biosensor external environment.
摘要:
Methods and system capable of processing specimens carried by slides within an automated histological staining system. A slide carrier is moved toward and into a temperature-controlled internal environment of a stainer within the system. The slide carrier carries a first slide and a second slide, and the first and second slides can carry a first specimen and a second specimen, respectively. The first and second specimens are stained with at least one of a staining reagent and a counterstaining reagent while the first and second slides are within the internal environment and while an average temperature of the internal environment is greater than ambient temperature. The slide carrier can be moved out of the internal environment after staining one or both specimens.
摘要:
This disclosure is directed to an apparatus and method for spreading a fluid across a substrate. A spreader for spreading a fluid across a substrate includes a wiper and a frame. The wiper and the frame may mate to permit translation of the wiper across, and with respect to, the frame. The wiper spreads the fluid across the substrate and the frame supports the wiper and the substrate. The frame may also include a ramp to cause a portion of the wiper to lift away from the substrate.
摘要:
A sample holding device for use in transverse illumination of a sample or sub-components of a sample comprising: a support substrate comprising a sample well adapted to contain and be compatible with said sample wherein said well is provided on at least one wall with an angled reflective surface adjacent said sample well which when in use directs a transverse light beam from a light source through a sample contained within said sample well to provide substantially transverse illumination of a sample contained therein and imaging the sample using a single objective.
