Apparatus for manipulating droplets by electrowetting-based techniques
InactiveUS6911132B2Improve controllabilityImprove accuracyBurnersElectrostatic separatorsElectricityControl manner
An apparatus is provided for manipulating droplets. The apparatus is a single-sided electrode design in which all conductive elements are contained on one surface on which droplets are manipulated. An additional surface can be provided parallel with the first surface for the purpose of containing the droplets to be manipulated. Droplets are manipulated by performing electrowetting-based techniques in which electrodes contained on or embedded in the first surface are sequentially energized and de-energized in a controlled manner. The apparatus enables a number of droplet manipulation processes, including merging and mixing two droplets together, splitting a droplet into two or more droplets, sampling a continuous liquid flow by forming from the flow individually controllable droplets, and iterative binary or digital mixing of droplets to obtain a desired mixing ratio.

Tandem UV chamber for curing dielectric materials
InactiveUS20060251827A1Improve uniformityDrying solid materials with heatSemiconductor/solid-state device manufacturingUltravioletProcess region
An ultraviolet (UV) cure chamber enables curing a dielectric material disposed on a substrate and in situ cleaning thereof. A tandem process chamber provides two separate and adjacent process regions defined by a body covered with a lid having windows aligned respectively above each process region. One or more UV bulbs per process region that are covered by housings coupled to the lid emit UV light directed through the windows onto substrates located within the process regions. The UV bulbs can be an array of light emitting diodes or bulbs utilizing a source such as microwave or radio frequency. The UV light can be pulsed during a cure process. Using oxygen radical / ozone generated remotely and / or in-situ accomplishes cleaning of the chamber. Use of lamp arrays, relative motion of the substrate and lamp head, and real-time modification of lamp reflector shape and / or position can enhance uniformity of substrate illumination.

Luminescent ink for printing of organic luminescent devices
InactiveUS6372154B1Improve efficiencyEasy transitionSolid-state devicesSemiconductor/solid-state device manufacturingSolventOrganic compound
Organic luminescent ink (L-ink) is disclosed for use in printing thin films of organic luminescent material. The L-ink is particularly useful in fabricating organic optoelectronic devices, e.g. organic luminescent devices. The L-ink contains at least one organic luminescent material mixed with a solvent and other functional additives to provide the necessary optical, electronic and morphological properties for light-emitting devices (LEDs). The additives play an important role either for enhanced thin film printing or for better performance of the optoelectronic device. The functional additives may be chemically bound to the luminescent compounds or polymers. Luminescent organic compounds, oligomers, or polymers with relatively low solution viscosity, good thin film formability, and good charge transporting properties, are preferred. The L-inks can be cross-linked under certain conditions to enhance thin film properties. The L-ink can be used in various printing methods, such as screen printing, stamp printing, and preferably ink-jet printing (including bubble-jet printing).
