  • Patent number: 11280019
    Abstract: One embodiment relates to a substrate carrier for use in electroplating a plurality of substrates. The substrate carrier comprises a non-conductive carrier body on which the substrates are to be held. Electrically-conductive lines are embedded within the carrier body, and a plurality of contact clips are coupled to the electrically-conductive lines embedded within the carrier body. The contact clips hold the substrates in place and electrically couple the substrates to the electrically-conductive lines. The non-conductive carrier body is continuous so as to be impermeable to flow of electroplating solution through the non-conductive carrier body. Other embodiments, aspects and features are also disclosed.

    Abstract: Methods for forming an ultra thin structure using a method that includes trimming a mask layer during an etching process are provided. The embodiments described herein may be advantageously utilized to fabricate a submicron structure on a substrate having a critical dimension less than 55 nm and beyond. In one embodiment, a method of forming a submicron structure on a substrate may include providing a substrate having a patterned photoresist layer disposed on a film stack into an etch chamber, wherein the film stack includes at least a hardmask layer disposed on an underlying layer, trimming the photoresist layer to a first predetermined critical dimension, etching the hardmask layer through openings defined by the trimmed photoresist layer, trimming the hardmask layer to a second predetermined critical dimension, and etching the underlying layer through openings defined by the trimmed hardmask layer.

  • Patent number: 6949203
    Abstract: An integrated in situ etch process performed in a multichamber substrate processing system having first and second etching chambers. In one embodiment the first chamber includes an interior surface that has been roughened to at least 100 Ra and the second chamber includes an interior surface that has a roughness of less than about 32 Ra. The process includes transferring a substrate having formed thereon in a downward direction a patterned photoresist mask, a dielectric layer, a barrier layer and a feature in the substrate to be contacted into the first chamber where the dielectric layer is etched in a process that encourages polymer formation over the roughened interior surface of the chamber. The substrate is then transferred from the first chamber to the second chamber under vacuum conditions and, in the second chamber, is exposed to a reactive plasma such as oxygen to strip away the photoresist mask deposited over the substrate.

  • Patent number: 6829056
    Abstract: A substrate processing apparatus has a chamber having a substrate support, gas distributor, gas energizer, and gas exhaust port. A process monitor is provided to monitor features in a first region of the substrate and generate a corresponding first signal, and to monitor features in a second region of the substrate and generate a second signal. A chamber controller receives and evaluates the first and second signals, and operates the chamber in relation to the signals. For example, the chamber controller can select a process recipe depending upon the signal values. The chamber controller can also set a process parameter at a first level in a first processing sector and at a second level in a second processing sector. The apparatus provides a closed control loop to independently monitor and control processing of features at different regions of the substrate.

    Abstract: A lightwave communication system is provided that includes first and second optical transmitters/receivers remotely located with respect to one another. First and second optical transmission paths couple the first transmitter/receiver to the second transmitter/receiver for bidirectionally transmitting optical information therebetween. First and second doped optical fibers are respectively disposed in the first and second optical transmission paths. Optical pump energy is supplied by first and second optical pump sources. The first optical pump source generates Raman gain in the first transmission path and the second optical pump source generates Raman gain in the second transmission path. A first optical coupler is provided for optically coupling pump energy from the first pump source to the second-doped optical fiber and a second optical coupler is provided for optically coupling pump energy from the second pump source to the first doped optical fiber.

  • Patent number: 6620289
    Abstract: A method and apparatus for processing a workpiece in a chamber by providing an asymmetric flow of process gas and processing the workpiece with the process gas. The asymmetric flow counteracts a non-uniform distribution of reactive species in the chamber. The asymmetric flow can be accomplished by introducing the process gas through a plurality of gas nozzles that communicate through a side wall of the chamber proximate a pump port while pumping gas with a pump coupled to the pump port. The inventive method can be used with a conventional processing chamber by only opening the gas nozzles closest to the pump and blocking any other gas nozzles. Alternatively, the method can be implemented in a processing chamber having gas nozzles located only proximate the pump port.
