    • The invention relates to a method for producing micromechanical structures having a raised lateral wall progression or an adjustable angle of inclination. The micromechanical structures are etched out of an SiGe-mixed semiconductor layer (3a, 3b, 30, 30a, 30b, 50) provided on, or deposited on, a silicon semiconductor layer (1, 10), by dry-chemical etching of the SiGe-mixed semiconductor layer (3a, 3b, 30, 30a, 30b, 50). The lateral wall progression of the micromechanical structure is formed by varying the germanium part in the SiGe-mixed semiconductor layer (3a, 3b, 30, 30a, 30b, 50) to be etched. There is a higher germanium part in regions that are to etched more aggressively. The variation of the germanium part in the SiGe-mixed semiconductor layer (3a, 3b, 30, 30a, 30b, 50) is adjusted by a method selected from a group wherein an SiGe-mixed semiconductor layer (3a, 3b, 30, 30a, 30b, 50) having a varying germanium content is deposited, wherein germanium is introduced into a silicon semiconductor layer or an SiGe-mixed semiconductor layer (3a, 3b, 30, 30a, 30b, 50), wherein silicon is introduced into a germanium layer or an SiGe-mixed semiconductor layer (3a, 3b, 30, 30a, 30b, 50), and/or wherein a SiGe-mixed semiconductor layer (3a, 3b, 30, 30a, 30b, 50) is subjected to thermal oxidation.

    • Methods for manufacturing a microstructure, wherein use is made of powder blasting and/or etching and a single mask layer with openings and structures of varying dimensions, characterized in that the mask layer at least at one given point in time has been wholly worn away within at least one region by mask erosion while the microstructure is not yet wholly realized. Use can be made of a combination of 'vertical' erosion, i.e. parallel to the thickness direction, and 'horizontal' erosion, i.e. perpendicularly of the thickness direction, of the mask layer. The horizontal mask erosion occurs at the edges of the mask structure. By selecting the size of the mask openings and the mask structures in a correct manner the mask layer in a region with smaller mask structures will be fully worn away at a given point in time, while in another region with larger structures the mask layer still has sufficient thickness to serve as protection against the powder blasting or etching.
    • 用于制造微结构的方法,其中使用粉末喷射和/或蚀刻以及具有不同尺寸的开口和结构的单个掩模层,其特征在于,至少在一个给定时间点的掩模层已经完全磨损在内部 至少一个区域通过掩模侵蚀而微结构尚未完全实现。 使用可以由掩模层的“垂直”侵蚀,即平行于厚度方向和“水平”侵蚀,即垂直于厚度方向的侵蚀的组合。 在掩模结构的边缘处发生水平掩模腐蚀。 通过以正确的方式选择掩模开口和掩模结构的尺寸,具有较小掩模结构的区域中的掩模层将在给定时间点被完全磨损,而在具有较大结构的另一区域中,掩模层仍具有 足够的厚度以作为防止粉末爆破或蚀刻的保护。
