Granted: 2001-03-11
Abstract: A capacitor with Enhanced capacitance per cell area is provided. A container supported by a substrate is formed, followed by a first layer of undoped substantially amorphous silicon. Next, a layer of heavily doped amorphous silicon is formed on the first layer. A second layer of undoped amorphous silicon is formed on the doped layer. The layers are formed in a non-oxidizing ambient so that no oxide is formed between the layers. The structure formed is planarized to form separate containers made from the doped and undoped amorphous silicon layers. Any remaining oxide is then removed from the exterior sidewalls. Selected ones of the first and second undoped layers are seeded and annealed to convert the first and second layers to HSG. A dielectric layer and second electrode are formed to complete the cell capacitor.

Abstract: In a miniature loudspeaker of the electromagnetic voice coil type with a stiff edge-driven concave diaphragm, a single suspension member attached to a particular location on the voice coil form achieves high excursion performance to deliver a full audio range, e.g. down to 100 Hz, in a cylindrical package of minimal thickness and diameter, e.g. 14 mm x 31 mm, suitable for sound systems of compact multi-media equipment including PC CRT monitors and flat displays as in lap top computers. The front end of the tubular voice coil form is attached to the perimeter of the diaphragm. The coaxial voice-coil-diaphragm assembly is supported by a single resilient surround suspension member with its inner edge attached around the voice coil form at a location that is offset slightly from the front end of the voice coil form so as to suspend the voice-coil diaphragm assembly in an optimal manner that enables large excursion performance. A permanent magnet system is contained in cup-shaped magnetic yoke that forms the main cylindrical outer wall and rear wall of the loudspeaker. Inside the rear wall is mounted a shallow cylindrical permanent magnet with a circular front pole piece defining, at its perimeter facing the inside rim of the yoke, an annular magnetized air gap in which the voice coil vibrates axially in response to current in the voice coil. Around a front region of the cylindrical outer wall of the loudspeaker is attached a plastic mounting ring that is configured to provide an attachment surface for the outer flange of the surround suspension member and also to provide attachment of the loudspeaker to a host panel or enclosure. The mounting ring may be configured to provide convenient mounting to a plastic cabinet or panel in a snap-in manner without additional mounting hardware.

Granted: 2004-09-11
Abstract: The sieving apparatus for a bio-chip, which has a light source, a HOE unit, a splitter, an objective lens, a filter, and an optical signal sensor. The HOE unit is coupled with a light source, so as to diffract the light into a zeroth order beam and a first order beam. The splitter is coupled to the HOE unit, so as to lead the two beams to the objective lens, which further leads the two beams to the bio-chip, in which the first order beam is incident onto the bio-chip from an incident angle, causing a florescent light from the sample. The bio-chip also reflects the zeroth order beam. Both the reflected zeroth order beam and the fluorescent light travel through the objective lens and the splitter. The filter is coupled to the splitter, so that an undesired portion of the light beams incident on the splitter is filtered. The optical sensor receives the light beams after the filter. The zeroth order beam is used to generate a focusing signal and a tracking signal. Alternatively, the sensor can be fixed but the bio-chip is shifted by the servo system.
