Abstract: A method of partially imaging an imaging surface of a substrate (50) with a plurality of layers of marking material (10) which have at least one common boundary within a print pattern that covers only certain portions of the substrate and not other portions of the substrate. The method includes applying initial superimposed layer of marking material (10) to a base layer (23) and removing portions of the initial superimposed layers of marking material and leaving the desired residual layer portions in the desired print pattern directly applied to the imaging surface of the substrate. The method typically includes the transfer of marking material onto the imaging surface of the substrate. The method has many variants, which can be used to make one-way or other vision control panels, typically using a ceramic ink decal carrier to image a glass sheet with ceramic ink that is then fused onto the glass, which is optionally tempered, in a suitable furnace.

Abstract: An elastic film laminate includes a first film and at least one second film. The first film is elastomeric in at least one direction and can be reversibly stretched by a length &Dgr;lA during a deformation without demonstrating substantial residual deformation &Dgr;la. The second film is made of a deformable plastic connected with the first film in localized connection regions less than the entire length of the first film. The second film has received a permanent deformation &Dgr;lb significantly greater than the residual deformation &Dgr;la, by means of a common deformation by a length &Dgr;lA, so that the second film is permanently deformed between the localized connection regions. In a renewed deformation of the film laminate above a limit range of deformation, where &Dgr;l>&Dgr;lA applies, the second film exhibits a reaction force that causes the tensile force required for further stretching of the laminate to increase suddenly.

Abstract: A method for patterning different types of surface features on a semiconductor substrate (e.g. metal pads, etched pits and grooves) where the features are accurately located by a single mask. First, a dielectric layer is formed on the substrate. Next, an etch-resistant metal layer is formed on the dielectric and patterned according to a mask. Then, a patterned resist mask (e.g. PMMA) is formed on the patterned metal so that areas of the dielectric are exposed. The resist mask has edges that lie on top of the patterned metal layer. Therefore, the exposed dielectric areas are bounded by patterned metal. Then, the dielectric layer is etched using a directional dry etch to expose the underlying semiconductor substrate. Then, the semiconductor substrate is etched. The dielectric layer functions as a mask in the substrate etching step. Since the metal pattern determines the areas of the substrate that are etched, all the features are located according to the original mask that defined the metal pattern.
