    Abstract: A buffer layer for promoting electron mobility. The buffer layer comprises amorphous silicon layer (a-Si) and an oxide-containing layer. The a-Si has high enough density that the particles in the substrate are prevented by the a-Si buffer layer from diffusing into the active layer. As well, the buffer, having thermal conductivity, provides a good path for thermal diffusion during the amorphous active layer's recrystallization by excimer laser annealing (ELA). Thus, the uniformity of the grain size of the crystallized silicon is improved, and electron mobility of the TFT is enhanced.

    Abstract: It is an object to provide a semiconductor device including an oxide semiconductor, in which miniaturization of a transistor is achieved and the concentration of an electric field is relieved. The width of a gate electrode is reduced and a space between a source electrode layer and a drain electrode layer is shortened. By adding a rare gas in a self-alignment manner with the use of a gate electrode as a mask, a low-resistance region in contact with a channel formation region can be provided in an oxide semiconductor layer. Accordingly, even when the width of the gate electrode, that is, the line width of a gate wiring is small, the low-resistance region can be provided with high positional accuracy, so that miniaturization of a transistor can be realized.

  • Patent number: 8003985
    Abstract: Apparatus having a dielectric containing scandium and gadolinium can provide a reliable structure with a high dielectric constant (high k). In an embodiment, atomic layer deposition (ALD) can be used to form a nanolaminate dielectric of gadolinium oxide (Gd2O3) and scandium oxide (Sc2O3) In an embodiment, a dielectric structure can be formed by depositing gadolinium oxide by atomic layer deposition onto a substrate surface using precursor chemicals, followed by depositing scandium oxide onto the substrate using precursor chemicals, and repeating to form the thin laminate structure. A dielectric containing scandium and gadolinium may be used as gate insulator of a MOSFET, a capacitor dielectric in a DRAM, as tunnel gate insulators in flash memories, as a NROM dielectric, or as a dielectric in other electronic devices, because the high dielectric constant (high k) of the film provides the functionality of a much thinner silicon dioxide film.

  • Patent number: 7960261
    Abstract: The present invention relates to a method for manufacturing a polycrystalline semiconductor film that can be used for a semiconductor device. In the method, an amorphous semiconductor film is irradiated with a femtosecond laser to be crystallized. By laser irradiation using a femtosecond laser, when an amorphous semiconductor film over which a cap film is formed is crystallized with a laser, it becomes possible to perform crystallization of the semiconductor film and removal of the cap film at the same time. Therefore, a step of removing the cap film in a later step can be omitted.

    Abstract: A process for forming at least one transistor on a substrate is described. The substrate comprises a polyimide and a nanoscopic filler. The polyimide is derived substantially or wholly from rigid rod monomers and the nanoscopic filler has an aspect ratio of at least 3:1. The substrates of the present disclosure are particularly well suited for thin film transistor applications, due at least in part to high resistance to hygroscopic expansion and relatively high levels of thermal and dimensional stability.
