    Abstract: Engineered substrates having thermally opaque materials for preventing transmission of radiative energy during epitaxial growth processes and for separating substrates from epitaxially grown semiconductor structures and associated systems and methods are disclosed herein. In several embodiments, for example, an engineered substrate can be manufactured by forming a thermally opaque material at an upper surface of a handle substrate and bonding an epitaxial formation structure on the handle substrate such that the thermally opaque material is between the epitaxial formation structure and the handle substrate. In various embodiments, the thermally opaque material at least partially blocks radiative heat transmission between the handle substrate and the epitaxial formation structure, for example, to provide increased accuracy of epitaxy process temperature measurements and/or increased uniformity of epitaxy growth characteristics across the engineered substrate.

  • Publication number: 20150090996
    Abstract: A voltage equal to the threshold value of a TFT (106) is held in capacitor unit (109). When a video signal is inputted from a source signal line, the voltage held in the capacitor unit is added thereto and a resultant signal is applied to a gate electrode of the TFT (106). Even when a threshold value is varied for each pixel, each threshold value is held in the capacitor unit (109) for each pixel. Thus, the influence of a variation in threshold value can be eliminated. Further, holding of the threshold value is conducted by only the capacitor unit (109) and a charge does not move at writing of a video signal so that a voltage between both electrodes is not changed. Thus, it is not influenced by a variation in capacitance value.

  • Publication number: 20150091001
    Abstract: In a miniaturized transistor, a gate insulating layer is required to reduce its thickness; however, in the case where the gate insulating layer is a single layer of a silicon oxide film, a physical limit on thinning of the gate insulating layer might occur due to an increase in tunneling current, i.e. gate leakage current. With the use of a high-k film whose relative permittivity is higher than or equal to 10 is used for the gate insulating layer, gate leakage current of the miniaturized transistor is reduced. With the use of the high-k film as a first insulating layer whose relative permittivity is higher than that of a second insulating layer in contact with an oxide semiconductor layer, the thickness of the gate insulating layer can be thinner than a thickness of a gate insulating layer considered in terms of a silicon oxide film.
