摘要： Provided is a silicon-containing layer forming composition for forming a silicon-containing layer which exhibits an anti-reflective function during exposure in a multilayer resist process and, during dry etching, shows a high etching rate against a plasma of fluorine-based gas and a low etching rate against a plasma of oxygen-based gas. The silicon-containing layer forming composition includes a polysiloxane compound having a structural unit of the formula: [(R1)bR2mSiOn/2] and a solvent. In the formula, R1 is a group represented by the following formula: (where a is an integer of 1 to 5; and a wavy line means that a line which the wavy line intersects is a bond); R2 is each independently a hydrogen atom, a C1-C3 alkyl group, a phenyl group, a hydroxy group, a C1-C3 alkoxy group or a C1-C3 fluoroalkyl group; b is an integer of 1 to 3; m is an integer of 0 to 2; n is an integer of 1 to 3; and a relationship of b+m+n=4 is satisfied.

摘要： The disclosure relates to an improved glass product having a multifunctional coating or a durable top coat over a functional coating. The glass product may include a functional coating on that is most effective on a surface exposed to various mechanical and chemical elements. The disclosed coating provides a durable protective coating over the functional layer to provide protection over the functional layer on an exposed surface. Alternatively, the functional coating may be applied to the protective coating with a porous, nano-structured surface, which protects the functional coating applied thereto.

摘要： An automotive laminated glass includes a thermoplastic interlayer film, a curved first glass sheet, and a curved second glass sheet. The thermoplastic interlayer film is disposed between the first and second glass sheets. The first glass sheet is a 0.7- to 3-mm thick non-chemically strengthened glass sheet including a convex-side first main surface and a concave-side second main surface facing the thermoplastic interlayer film. The second glass sheet is an ion-exchanged, 0.3- to 1.5-mm thick chemically strengthened glass sheet including a convex-side third main surface facing the thermoplastic interlayer film and a concave-side fourth main surface. The second glass sheet is thinner than the first glass sheet, and is adjusted to have a curvature equal to the curvature of the first glass sheet. A compressive stress layer on the concave-side fourth main surface is thicker than a compressive stress layer on the convex-side third main surface.

摘要： Disclosed is a dry etching method for etching a metal film on a substrate with an etching gas containing a β-diketone and an additive gas, wherein the metal film contains a metal element capable of forming a complex with the β-diketone; and wherein the amount of water contained in the etching gas is 30 mass ppm or less relative to the amount of the β-diketone. It is preferable that the β-diketone used for the dry etching method is supplied from a β-diketone filled container, wherein the β-diketone filled container has a sealed container body filled with a β-diketone whose water content is 15 mass ppm or less relative to the β-diketone. This etching method enables etching of the metal film while suppressing etching rate variations from the initial stage to the later stage of use of the filled container.
