摘要:
The present invention provides methods and systems for discretized, combinatorial processing of regions of a substrate such as for the discovery, implementation, optimization, and qualification of new materials, processes, and process sequence integration schemes used in integrated circuit fabrication. A substrate having an array of differentially processed regions thereon is processed by delivering materials to or modifying regions of the substrate.
摘要:
An apparatus and method based on the apparatus is disclosed for automated single molecule or molecular assemblage detection via light irradiation and detection of transient FRET between a donor or acceptor bound to an immobilized single molecule or molecular assemblage and a corresponding acceptor or donor associated with, covalently bonded to, a reagent, where the donor or acceptor associated with the reagent is transiently in FRET proximity to the acceptor or donor associated with the immobilized molecule or molecular assemblage.

A polymer synthesis apparatus (20) for building a polymer chain including a head assembly (21) having an array of nozzles (22) with each nozzle coupled to a reservoir (23) of liquid reagent (24), and a base assembly (25) having an array of reaction wells (26). A transport mechanism (27) aligns the reaction wells (26) and selected nozzles (22) for deposition of the liquid reagent (24) into selected reaction wells (26). A sliding seal (30) is positioned between the head assembly (21) and the base assembly (25) to form a common chamber (31) enclosing both the reaction well (26) and the nozzles (22) therein. A gas inlet (70) into the common chamber (31), upstream from the nozzles (22), and a gas outlet (71) out of the common chamber (31), downstream from the nozzles (22), sweeps the common chamber (31) of toxic fumes emitted by the reagents. Each reaction well (26) includes an orifice (74) extending into the well (26) which is of a size and dimension to form a capillary liquid seal to retain the reagent solution (76) in the well (26) for polymer chain growth therein. A pressure regulating device (82) is provided for controlling a pressure differential, between a first gas pressure exerted on the reaction well (26) and a second gas pressure exerted on an exit (80) of the orifice, such that upon the pressure differential exceeding a predetermined amount, the reagent solution (76) is expelled from the well (26) through the orifice (74). A method of synthesis of a polymer chain in a synthesis apparatus (20) is also included.

A device for inspecting microscopic objects. A plurality of LEDS is arranged in an array underneath a lens. Some of the LEDS are lighted and some of the LEDS are unlighted. A computer is in control of the LED array. The computer turns on selected LEDS from the array to form the lighted LEDS. Also, the computer turns off selected LEDS from the array to form the unlighted LEDS. The lighted LEDS form a pattern of lighted LEDS underneath the lens. In a preferred embodiment, the lens is connected to a computer controlled camera and the microscopic objects are microscopic crystals.

Apparatus and methods are disclosed for storing a plurality of supports having a plurality of chemical compounds bound to the surfaces of the supports. In the apparatus, a mechanism for diffusively introducing pressurized gas into the apparatus is in fluid communication with an outlet element comprising a plurality of openings. A holding chamber for the supports is in fluid communication with the outlet element. The outlet element and the holding chamber are disposed such that gas flow through the chamber is substantially uniform and unidirectional. The holding chamber comprises an opening sufficient to permit movement of the supports to and from the holding chamber and comprises a plurality of holding elements for holding the supports.
