摘要:
A non-linear element is formed on a flexible substrate by securing the substrate to a rigid carrier, forming the non-linear element, and then separating the flexible substrate from the carrier. The process allows flexible substrates to be processed in a conventional fab intended to process rigid substrates. In a second method, a transistor is formed on a insulating substrate by forming gate electrodes, depositing a dielectric layer, a semiconductor layer and a conductive layer, patterning the conductive layer to form source, drain and pixel electrodes, covering the channel region of the resultant transistor with an etch-resistant material and etching using the etch-resistant material and the conductive layer as a mask, the etching extending substantially through the semiconductor layer between adjacent transistors. The invention also provides a process for forming a diode on a substrate by depositing on the substrate a first conductive layer, and a second patterned conductive layer and a patterned dielectric layer over parts of the first conductive layer, and etching the first conductive layer using the second conductive layer and dielectric layer as an etch mask. Finally, the invention provides a process for driving an impulse-sensitive electro-optic display.

An electro-optic display comprises a substrate (100), non-linear devices (102) disposed substantially in one plane on the substrate (100), pixel electrodes (106) connected to the non-linear devices (102), an electro-optic medium (110) and a common electrode (112) on the opposed side of the electro-optic medium (110) from the pixel electrodes (106). The moduli of the various parts of the display are arranged so that, when the display is curved, the neutral axis or neutral plane lies substantially in the plane of the non-linear devices (102).

摘要:
A thin-film transistor includes a gate electrode having a first gate electrode edge and a second gate electrode edge opposite the first gate electrode edge. The TFT also includes a drain electrode having a first drain electrode edge that overlaps the first gate electrode edge, and a second drain electrode edge that overlaps the second gate electrode edge. A method for fabricating a diode array for use in a display includes deposition of a conductive layer adjacent to a substrate, deposition of a doped semiconductor layer adjacent to the substrate, and deposition of an undoped semiconductor layer adjacent to the substrate. A display pixel unit provides reduced capacitative coupling between a pixel electrode and a source line. The unit includes a transistor, the pixel electrode, and the source line. The source line includes an extension that provides a source for the transistor. A patterned conductive portion is disposed adjacent to the source line. Another display pixel unit provides reduced pixel electrode voltage shifts. The unit includes a transistor, a pixel electrode, a source line and a balance line. The invention also provides a driver for driving a display provided with such a balance line.

Semiconductor devices are described wherein current flow in the device is confined between the rectifying junctions (e.g., p-n junctions or metal-semiconductor junctions). The device provides non-punch-through behavior and enhanced current conduction capability. The devices can be power semiconductor devices as such as Junction Field-Effect Transistors (VJFETs), Static Induction Transistors (SITs), Junction Field Effect Thyristors, or JFET current limiters. The devices can be made in wide bandgap semiconductors such as silicon carbide (SiC). According to some embodiments, the device can be a normally-off SiC vertical junction field effect transistor. Methods of making the devices and circuits comprising the devices are also described.

Interfaces that are portions of semiconductor structures used in integrated circuits and optoelectronic devices are described. In one instance, the semiconductor structure has an interface including a semiconductor surface, an interfacial layer including sulfur, and an electrically active layer (e.g., a dielectric or a metal). Such an interface can inhibit oxidation and improve the carrier mobility of the semiconductor structures in which such an interface is incorporated. The interfacial layer can be created by exposure of the semiconductor surface to sulfur donating compounds (e.g., H2S or SF6) and, optionally, heating.

Vertical junction field effect transistors (VJFETs) having improved heat dissipation at high current flow while maintaining the desirable specific on-resistance and normalized saturated drain current properties characteristic of devices having small pitch lengths are described. The VJFETs comprise one or more electrically active source regions in electrical contact with the source metal of the device and one or more electrically inactive source regions not in electrical contact with the source metal of the device. The electrically inactive source regions dissipate heat generated by the electrically active source regions during current flow.
