A method of realizing an active matrix display device having flexibility is provided. Further, a method for reducing parasitic capacitance between wirings formed on different layers is provided. After fixing a second substrate to a thin film device formed on a first substrate by bonding, the first substrate is removed, and wirings and the like are formed in the thin film device. The second substrate is removed next, and an active matrix display device having flexibility is formed. Further, parasitic capacitance can be reduced by forming wirings, after removing the first substrate, on the side in which a gate electrode over an active layer is not formed.
摘要:
The present invention has the object of obtaining a display device with a sufficient storage property without degrading the aperture ratio when high definition is to be achieved for the display device. In the active matrix display device, a good storage property can be obtained without degrading the aperture ratio by disposing the storage element below the pixel TFT area as shown in FIG. 3. Moreover, even when the area of the capacitor element is reduced, a sufficient amount of the capacitor can be obtained by laminating a plurality of capacitor elements.

摘要:
A miniature implantable drug delivery capsule system. The drug delivery system (400) comprises one or more ball semiconductor aggregations (404) and (406) facilitating release of a drug stored in a reservoir (402). The first aggregate (404) is used for sensing and memory, and a second aggregation (406) for control aspects, such as for pumping and dispensing of the drug. Notably, the aggregates (404) and (406) may be interconnected by a common bus (410) for communication purposes, or may be implemented to operate independently of each other. Each aggregate (404) and (406) is encased in a semipermeable membrane (408) to allow species which are to be monitored, and drugs to be delivered, to freely diffuse. The system (400) may communicate with a remote control system, or operate independently on local power over a long period for delivery of the drug based upon a request of the patient, timed-release under control by the system (400), or delivery in accordance with measured markers.
摘要:
A substantially spherical semiconductor ball implanted in orthopedic structures for sensing and/or stimulation. In one embodiment, a vertebral column (800) having a number of intervertebral discs (802) interspersed among respective vertebral bodies (804), material placed in intervertebral discs (802) allows for a semi-synthetic vertebral disc (806) to be constructed. The artificial intervertebral disk (806) contains one or more ball sensors (808) located within the body of the disk (806) in order to monitor the compression forces. Conventionally, the semi-synthetic disc (806) is monitored only retrospectively, and visualized on x-ray. In this particular embodiment, any of a number of semi-synthetic intervertebral discs (806) can be implanted with one or more ball sensors (808) such that stress and compression forces can be monitored to assure proper alignment of vertebrae (810) in the vertebral column (800), and to monitor the development of any nonphysiologic forces due to vertebral degeneration, disk malfunction, and so on.
摘要:
A method of tumor ablation using injectable thermal-sensing balls. A catheter system (115) is used to inject a slurry (134) of thermal-sensing balls (136) into a tumor (122) located in, for example, a liver (120). The catheter system (115) comprises a catheter (128) and a specialized syringe (129) consisting of a housing (130) and a plunger (132). The housing (130) includes a cylindrical chamber having the slurry (134) of thermal-sensing balls (136). The catheter (128) is inserted retrograde into the femoral artery and passed to the site of the tumor (122). The hepatic artery (124) branches into smaller vessels, one of which is a tumor artery (126) which feeds the tumor (122). The tip of the catheter (128) is placed in the tumor artery (126) guided by conventional fluoroscopy. The injected balls (136) then receive energy from an external control system (110). The system (110) comprises a control panel (114) as an operator interface for controlling the system (110) and reading data therefrom. A CPU (112) is used for control and monitor of the operation, and transmits power and signals to the injected balls (136) via a radiating antenna (118), which energy is converted into heat to increase the temperature of the tumor (122). The temperature of the balls (136) can then be read from one or more onboard temperature sensors, and displayed to the operator for accurate control of the tumor temperature.
摘要:
A radiation dosimetry system (110) using miniature implanted transponder balls. A patient having a tumor that is the target of the radiation treatment lies in a treatment area with the tumor positioned beneath a target (112) used for alignment purposes. The system (110) is controlled and monitored by a CPU (114) which receives instructions from a radiologist operating a control panel (116), and displays control parameters, data and graphics to the radiologist on a display (118). The CPU (114) controls an RF system operating through a broad-band antenna (120) and directed at the target area (112). The CPU (114) controls operation of a radiation source (122), which may be a conventional linear accelerator, for directing radiation at the target area (112). The radiation source (122) includes a collimator (124) or similar apparatus for shaping a radiation beam for accurate application to the target area (112). A pair of RF receivers (126) and (128) are positioned such that they are spaced apart and opposite from the CPU antenna (120) with respective antennas (130) and (132) directed at the target area (112). Communication connections (133a), (133b), (133c), (133d) and (133e) interconnect the various elements of the system (110).
摘要:
A photolithography system and method for providing a mask image to a subject such as a wafer is provided. The mask images are divided into sub-patterns and sequentially provided to a pixel panel, such as a deformable mirror device or a liquid crystal display. The pixel panel converts each sub-pattern into a plurality of pixel elements. Each of the pixel elements is then simultaneously focused to discrete, non-contiguous portions of the subject through a microlense array. The subject and pixel elements are then moved (e.g., one or both may be moved) and the next sub-pattern in the sequence is provided to the pixel panel. As a result, light can be projected on the subject, according to the pixel elements, to create a contiguous image on the subject.
摘要:
A spherical shaped solar diode having an n-type substrate surrounded by a p-type layer of semiconductor material is disclosed. In addition, a plurality of hetero-junction super lattice structures are formed surrounding the p-type layer. The plurality of hetero-junction super lattice structures include alternating layers of Si and SeBeTe. The plurality of hetero-junction super lattice structures adapt the diode to convert higher energy light (as compared to 1.1eV light) to electrical energy. The diodes are formed into a solar panel assembly. The panel assembly includes a wire mesh to secure the diodes and electrically contact one electrode of each diode. A dimpled sheet is also used for securing the diodes and electrically contacting the other electrode of each diode. The diodes are positioned adjacent to the dimpled sheet so that when light is applied to the solar panel assembly, the diodes are exposed to the light on a majority of each diode's surface.
