摘要:
In one aspect, the invention provides a fabrication method. Before the fabrication of the structure, a mask layer, for example a hard mask, is applied to a layer. The mask layer has at least two layers composed of materials that can be etched selectively with respect to one another. In a first etching process, the structure is introduced into the layer. Subsequently, the first etching process is interrupted at a point in time in order to etch away a topmost layer of the hard mask selectively with respect to the underlying layer by means of a second etching process and, subsequently, the first etching process is continued for fabricating the structure with the new topmost layer.
摘要:
A PVD method and a PVD apparatus use a rotating magnetic field in order to increase the yield. The magnetic field is provided such that it essentially vanishes, at least in a time average, outside a rotation axis of the magnetic field in sectors of the target region of the PVD apparatus. In this manner the PVD method and the PVD apparatus achieve a uniform coating.
摘要:
An inner contour of the compensation frame (2) is configured in polygonal fashion in order to receive the substrate (1). With the substrate (1) having been received, the compensation frame (2) encloses the substrate (1) at the outer edge thereof. A partial region (3a) of an upper main area (3) of the compensation frame (2) runs at a given height (h) above the plane of an upper main area (1a) of the substrate (1) when the latter has been received into the compensation frame (2). Moreover, a further partial region (3b) of the upper main area (3) of the compensation frame runs essentially at the same height as the plane of the upper main area (3) of the substrate (1) when the latter has been received into the compensation frame (2).
