摘要:
The present invention provides a liquid crystal display device with high image visibility at low power consumption and produced at low cost by using an interlayer dielectric film, which has low dielectric constant, high heat-resistant property, high optical transmissivity, high film thickness and high flattening property produced at low cost. An organic siloxane dielectric film is used as an interlayer dielectric film of the liquid crystal display device. A ratio of nitrogen content to silicon content (Ni content/Si content) in the interlayer dielectric film is controlled to 0.04 or more in the element ratio. The limiting film thickness to suppress and limit the cracking caused by the thickening of the interlayer dielectric film is set to 1.5 μm or more.

An image display device capable of high-resolution and smooth moving image display, equipped with TFTs in an n-type (or p-type) semiconductor layer with a high on-off ratio and a low resistance. In polysilicon crystallization by laser annealing, an n-type (or p-type) semiconductor layer with a low resistance is produced by performing the following processes in order: implanting nitrogen (N) ions into an amorphous silicon precursor semiconductor film; laser crystallization; implanting n-type (or p-type) dopant ions; and annealing for dopant activation. When fabricating TFTs, this low-resistance semiconductor layer is used to form a source and a drain. Since C, N, and O impurities decrease the mobility of the TFTs, polysilicon is used in which the contaminants concentrations meet the following conditions: carbon concentration ≦3×1019 cm−3, nitrogen concentration ≦5×1017 cm−3, and oxygen concentration ≦3×1019 cm−3.

摘要:
A layer of material is transformed from a first state to a second state by the application of energy from an energy beam. For example, large direction- and location-controlled p-Si grain growth utilizes recrystallization of amorphous silicon from superpositioned laser irradiation. The superpositioned laser irradiation controls cooling and solidification processes that determine the resulting crystal structure. Specifically, a first laser beam of a first pulse duration is used to melt an amorphous silicon (a-Si) film and to create a temperature gradient. After an initial delay, a second laser beam with shorter pulse duration is superpositioned with the first laser beam. When a-Si is irradiated by the second laser beam, the area heated by the first laser beam becomes completely molten. Spontaneous nucleation is initiated in the supercooled liquid-Si when the liquid-Si temperature drops below the nucleation temperature. However, the central part of the liquid pool subjected to continued heating by the first laser beam cools down slowly. Grains nucleated in the periphery of the fully molten spot can therefore grow into the liquid-Si and extend in length until they collide at the center of the first laser beam spot. The first laser beam prolongs the molten Si phase and induces grain growth in a certain direction. The second laser beam triggers nucleation and controls grain location leading to subsequent lateral grain growth.

A superconducting device may include a superconducting weak link equipped with plural superconducting devices that are used as input-output terminals formed on the same plane and at least one current source for applying current to at least one of these superconducting electrodes. A superconducting device suitable for high integration can be realized as it enables structuring of a superconducting weak link 1 equipped with plural superconducting electrodes 101, 102, 103 and 104 that can be used as input-output terminals and changing symmetry of superconducting electrode arrangement through the form of a normal conductor 201 which is forming a superconducting weak link. In addition, when this superconducting device is used as a quasi-particle injection type device, a superconducting device with plural superconducting electrodes that can be used for a gate electrode, drain electrode or control electrode can be realized. Further, a superconducting device equipped with new functions (e.g. motion as a neuron device) which are capable of high integration can be realized by utilizing these characteristics. Furthermore, being a proximity effect type, superconducting weak link has an advantage of realizing an ultra highspeed, low electricity consuming switching device.
