摘要:
A method of forming poly-silicon thin film transistors is described. An amorphous silicon thin film transistor is formed on a substrate, and then the Infrared (IR) heating process is used. A gate metal and source/drain metal are heated rapidly, and conduct heat energy to an amorphous silicon layer. Next, crystallization occurs in the amorphous silicon layer to form poly-silicon. Therefore a poly-silicon thin film transistor is produced.

A method for fabricating a thin film transistor (“TFT”) device includes providing a substrate, forming a patterned amorphous silicon layer over the substrate including a pair of first regions, a second region disposed between the pair of first regions, and at least one third region, each of which being disposed between and contiguous with the second region and each of the pair of first regions, the second region including a sub-region contiguous with each of the at least one third region, forming a heat retaining layer over the substrate, irradiating the patterned amorphous silicon layer with a laser through the heat retaining layer to form a patterned crystallized silicon layer corresponding to the patterned amorphous silicon layer including a grain boundary extending substantially across a crystallized sub-region corresponding to the sub-region, and forming a patterned conductive layer over a portion of a crystallized second region of the patterned crystallized silicon layer corresponding to the second region of the patterned amorphous silicon layer.

The present invention discloses an active organic light emitting diode (AOLED) display structure. A color filter and thin film transistor organic light emitting diode (TFT-OLED) are incorporated on one substrate of the AOLED. Moreover, a Indium Tin Oxide(ITO)layer of the AOLED is deposited with a black matrix layer so as to lower light leakage effect and increase the contrast and color purity level in between pixels of the display. By adopting such technology, a flat panel display having large area, high resolution and low product cost is accordingly implemented.

An amorphous silicon layer is formed on a substrate, and then a protective layer and a reflective layer are formed in turn to form a film stack on portions of the amorphous silicon layer. The reflective layer is a metal material with reflectivity of laser, and the protective layer is able to prevent metal diffusion. When an excimer laser heats the amorphous silicon layer to crystallize the amorphous silicon, nucleation sites are formed in the amorphous silicon layer under the film stack of the protective layer and the reflective layer. Next, laterally expanding crystallization occurs in the amorphous silicon layer to form poly-silicon having crystal grains with size of micrometers and high grain order.

A digital programmable DC—DC voltage-down converter which can be used in a low voltage and low power digital circuit design is disclosed. The DC—DC voltage-down converter includes at least a digitally controlled oscillator (DCO), a pulse-width modulator (PWM), a gate driver, and a switching-type voltage-down converter. Duty cycle and operating frequency of the modulated signal are controlled by using two digital control signals. Furthermore, combining the pulse-width modulator and the digitally controlled oscillator (DCO), the duty cycle of the generated clock is more robustly stable for different frequencies during process variation.

A multi-layered complementary conductive line structure, a manufacturing method thereof and a manufacturing method of a TFT (thin film transistor) display array are provided. The process of TFT having multi-layered complementary conductive line structures does not need to increase the mask number in comparison with the currently process and is able to solve the resistance problem of the lines inside a display.
