摘要:
Methods of forming displays are described. The displays have zinc oxide row and column drivers integrated onto the same display substrate as zinc oxide pixel transistors and organic light emitting diodes. The organic light emitting diodes are prepared, at least in part, using a thermal transfer process from a donor sheet.
摘要:
Methods and displays utilize row and column drivers with ZnO channels that control pixel transistors with ZnO channels, which in turn address OLEDs of an array to produce images of a display screen. A display backplane including the ZnO row and column drivers and the OLEDs may be constructed by utilizing aperture masking or a combination of photolithography and aperture masking. Monolithic integration of the ZnO row and column drivers together with the ZnO pixel transistors is thereby achieved.

A method of making a patterned layer comprises directing a beam of vaporized material toward a reflector such that the beam of vaporized material impinges an impingement surface of the reflector and is redirected from the reflector through one or more apertures in a shadow mask and onto a deposition substrate to form a patterned material layer.
摘要:
Logic circuitry is powered by a partially rectified alternating current (ac) waveform. The waveform is partially rectified in the sense that it does not provide a clean, primarily dc power signal. Instead, it is possible to power logic circuitry with a waveform that includes a substantial ac component. The partially rectified ac waveform may be applied to logic circuitry incorporating thin film transistors based on amorphous or polycrystalline organic semiconductors, inorganic semiconductors or combinations of both.

In one embodiment, the invention is directed to aperture mask deposition techniques using aperture mask patterns formed in one or more elongated webs of flexible film. The techniques involve sequentially depositing material through mask patterns formed in the film to define layers, or portions of layers, of the circuit. A deposition substrate can also be formed from an elongated web, and the deposition substrate web can be fed through a series of deposition stations. Each deposition station may have an elongated web formed with aperture mask patterns. The elongated web of mask patterns feeds in a direction perpendicular to the deposition substrate web. In this manner, the circuit creation process can be performed in-line. Moreover, the process can be automated to reduce human error and increase throughput.

A method for making transistors comprises depositing source electrode and drain electrode features onto a substrate through a single aperture in a stationary shadow mask, said aperture having at least two opposing edges; wherein the shapes of the features are defined by the aperture and location of source materials in relation to the substrate.

A II-VI semiconductor light emitting device includes a II-VI semiconductor light emitting region and a II-VI semiconductor waveguide layer. A light absorbing layer is provided near the II-VI semiconductor waveguide layer, outside of the active region. The light absorbing layer absorbs extraneous radiation thereby reducing dark line defects (DLDs).

摘要:
Aperture masks and deposition techniques for using aperture masks are described. In addition, techniques for creating aperture masks and other techniques for using the aperture masks are described. The various techniques can be particularly useful in creating circuit elements for electronic displays and low-cost integrated circuits such as radio frequency identification (RFID) circuits. In addition, the techniques can be advantageous in the fabrication of integrated circuits incorporating organic semiconductors, which typically are not compatible with wet processes.
