Semiconductor Device and Manufacturing Method Thereof

To improve the reliability of a semiconductor device including a low-resistance material such as copper, aluminum, gold, or silver as a wiring. Provided is a semiconductor device including a pair of electrodes electrically connected to a semiconductor layer which has a stacked-layer structure including a first protective layer in contact with the semiconductor layer and a conductive layer containing the low-resistance material and being over and in contact with the first protective layer. The top surface of the conductive layer is covered with a second protective layer functioning as a mask for processing the conductive layer. The side surface of the conductive layer is covered with a third protective layer. With this structure, entry or diffusion of the constituent element of the pair of conductive layers containing the low-resistance material into the semiconductor layer is suppressed.

Long-term high temperature and humidity stable holographic optical data storage media compositions with exceptional high dynamic range

A novel photoimageable system for a two-chemistry system containing liquid photoreactive asymmetric acrylate compound containing sulfur, aromatic moieties, and optionally bromine, and an aluminum salt compound is disclosed. The photoimageable system has high dynamic range (M / #) and sensitivity and unexpectedly high temperature and high humidity resistance. The photoimageable system retains its dynamic range when exposed to 60° C. for 4 weeks while a composition without the aluminum salt compound lost 75% of its dynamic range under similar exposure conditions. In one embodiment, 2-10 weight % of a thio-butylacrylate dissolved in a two-component urethane matrix containing 0.002 to 1 weight % of the aluminum salt compound showed a dynamic range of greater than 5 for a 200 microns thick sample and retained more than 80% of the dynamic range after 4 weeks exposure at 60° C.

Surface-treated precoated metal sheet, process for producing same, and surface-treating solution

Disclosed is a surface-treated precoated metal sheet of which resistance against contamination with a photocatalyst and a self-cleaning function can be retained for a long period. Also disclosed are a method and a surface-treating solution for producing the surface-treated precoated metal sheet properly. The surface-treated precoated metal sheet is characterized by comprising a precoated metal sheet comprising an under metal sheet and an organic resin coating layer provided on the surface of the under metal sheet and a coating film having at least two layers, having a photocatalytic activity and formed on the precoated metal sheet, wherein the coating film having at least two layers comprises an inorganic-organic composite resin composed of a condensed product of an alkoxysilane selected from a group consisting of an alkoxysilane having an organic group selected from a group consisting of an alkyl group having 1 to 12 carbon atoms, an aryl group, a carboxyl group, a hydroxy group and a combination of two or more of these groups, an alkoxysilane having an epoxy group, an alkoxysilane having an amino group, a tetraalkoxysilane and a combination of two or more of the alkoxysilanes and contains a substance having a photocatalytic activity in such an amount that the content of the substance is highest in the outermost layer of the coating film and is gradually decreased toward an inner layer of the coating film.

Self-pumping hydrodynamic mechanical seal

InactiveUS20160097457A1Eliminates solid frictionFast formingEngine sealsInterference resistanceSolid particle
A self-pumping hydrodynamic mechanical seal includes a rotating ring (3) and a stationary ring (11). More than three sets of backward curved grooves (39) are provided on a seal face of the rotating ring (3), outlets of the backward curved grooves (39) are provided at an external diameter portion of the seal face of the rotating ring (3), and an inlet (31) connects with a seal chamber (1) through a duct (30) of the rotating ring (3) or the stationary ring (11). When the rotating ring (3) rotates, a medium in the backward curved grooves (39) is accelerated into a high-speed fluid; under a centrifugal force, the high-speed fluid moves to an external diameter side of the rotating ring (3), so as to be pumped into the seal chamber (1) and generates a low-pressure area at the inlets (31) of the backward curved grooves (39); the medium in the seal chamber (1) is driven by a pressure difference, so as to flow into the backward curved grooves (39) through the duct (30), for forming circulation of self-pumping. During pumping the high-speed fluid, a flow speed of the high-speed fluid is slowed and a pressure of the high-speed fluid is increased, as a flow sectional area of the backward curved grooves (39) is increased, so as to generate an opening force which separates the rotating ring (3) from the stationary ring (11). The seal has desirable capabilities of self-lubrication, self-flushing, solid particle interference resistance, and optimal sealing performance.
