    Abstract: Disclosed is a method for structuring a planar substrate made of a glass-type material, which is characterized by the following steps: - the thickness of the planar semiconductor substrate is reduced within at least one surface area thereof so as to obtain a surface area that is raised relative to the surface areas having a reduced thickness; - the raised surface area of the planar semiconductor substrate is structured by locally removing material in a mechanical manner so as to introduce recesses within the raised surface area; - the structured surface of the planar semiconductor substrate is connected to the glass-type planar substrate such that the glass-type planar substrate at least partly covers the surface area having a reduced thickness; - the connected planar substrates are heated up such that the glass-type planar substrate which covers the surface area having a reduced thickness forms a fluid-tight connection along with the surface area having a reduced thickness in a first heating phase which is carried out at negative pressure conditions, the planar substrate covering the recesses in a fluid-tight manner at negative pressure conditions, whereupon at least some areas of the glass-type material flow into the recesses of the structured surface of the planar semiconductor substrate in a second heating phase. Also disclosed are a glass-type planar substrate and the use thereof.

    Abstract: The invention relates to a production method for a micromechanical part, comprising at least the following steps: forming a main structure (10) of at least one component of the micromechanical part from at least one crystalline layer (12) of a substrate by means of a crystal orientation-independent etching step, and etching at least one area (18) in a defined crystal plane (20) away on the main structure (10) of the at least one component by means of a crystal orientation-dependent etching step. For said crystal orientation-dependent etching step, the defined crystal plane (20) in respect of which the at least one area (18) etched away on the main structure (10) is oriented is the crystal plane that features the lowest etching rate of all crystal planes. The invention further relates to a micromechanical part.

    Abstract: A highly aqueous, strongly basic planarizing solution and a process for its use to reducing or essentially eliminating protrusions or projections extending generally upwardly from a generally planar surface of polysilicon film produced by Low Temperature Poly Si (LTPS) annealing a film of amorphous silicon deposited on a substrate; the process including contacting the surface of the generally planar polysilicon film with the highly aqueous, strongly basic solution for a time sufficient to selectively etch the protrusions or projections from the surface of the generally planar polysilicon film without any significant etching of the generally planar polysilicon film, said highly aqueous, strongly basic solution being a solution having a pH of 12 or higher and comprising water, at least one strong base, and at least one etch rate control agent.
