摘要:
A method of fabricating a thin film transistor for an active matrix display using reduced masking operations includes patterning a gate on a substrate. A gate dielectric is formed over the gate and a semiconducting metal oxide is deposited on the gate dielectric. A channel protection layer is patterned on the semiconducting metal oxide overlying the gate to define a channel area and to expose the remaining semiconducting metal oxide. A source/drain metal layer is deposited on the structure and etched through to the channel protection layer above the gate to separate the source/drain metal layer into source and drain terminals and the source/drain metal layer and the semiconducting metal oxide are etched through at the periphery to isolate the transistor. A nonconductive spacer is patterned on the transistor and portions of the surrounding source/drain metal layer.

A method of annealing a metal oxide on a temperature sensitive substrate formation includes the steps of providing a temperature sensitive substrate formation and forming a spacer layer on a surface of the substrate formation. A metal oxide semiconductor device is formed on the spacer layer, the device includes at least a layer of amorphous metal oxide semiconductor material, an interface of the amorphous metal oxide layer with a dielectric layer, and a gate metal layer adjacent the layer of amorphous metal oxide semiconductor material and the interface. The method then includes the step of at least partially annealing the layer of metal oxide semiconductor material by heating the adjacent gate metal layer with pulses of infra red radiation to improve the mobility and operating stability of the amorphous metal oxide semiconductor material while retaining at least the amorphous metal oxide semiconductor material adjacent the gate metal layer amorphous.

Two-terminal switching devices of MIM type having at least one electrode formed by a liquid phase processing method are provided for use in active matrix backplane applications; more specifically, MIM devices with symmetric current-voltage characteristics are applied for LCD active matrix backplane applications, and MIM devices with asymmetric current-voltage characteristics are applied for active matrix backplane implementation for electrophoretic displays (EPD) and rotating element displays. In particular, the combination of the bottom metal, metal-oxide insulator and solution-processible top conducting layer enables high throughput, roll-to-roll process for flexible displays.

A long-wavelength VCSEL, and method of fabrication, includes a long-wavelength active region epitaxially grown on a compatible substrate with a high heat conductivity DBR mirror stack metamorphically grown on the active region. A supporting substrate is bonded to the DBR mirror stack and the compatible substrate is removed. A second mirror stack, either a DBR or a dielectric mirror stack, is formed on the opposite surface of the active region. Preferably, an InP based active region is grown on an InP based substrate and an AlAs/GaAs based metamorphic DBR mirror stack is metamorphically grown on the active region. The supporting substrate may be either an InP based substrate bonded to the active region or a layer of plated metal, such as copper, silver, gold, nickel, aluminum, etc.
