    摘要: By forming metal capacitors in the metallization structures of semiconductor devices, complex manufacturing sequences in the device level may be avoided. The process of manufacturing the metal capacitors may be performed on the basis of well-established patterning regimes of modern metallization systems by using appropriately selected etch stop materials, which may enable a high degree of compatibility for forming via openings in a metallization layer while providing a capacitor dielectric of a desired high dielectric constant in the capacitor.

    摘要: In sophisticated SOI devices, circuit elements, such as substrate diodes, may be formed in the crystalline substrate material on the basis of a substrate window, wherein the pronounced surface topography may be compensated for or at least reduced by performing additional planarization processes, such as the deposition of a planarization material, and a subsequent etch process when forming the contact level of the semiconductor device.

    摘要: In an SOI semiconductor device, substrate diodes may be formed on the basis of a superior design of the contact level and the metallization layer, thereby avoiding the presence of metal lines connecting to both diode electrodes in the critical substrate diode area. To this end, contact trenches may be provided so as to locally connect one type of diode electrodes within the contact level. Consequently, additional process steps for planarizing the surface topography upon forming the contact level may be avoided.

    摘要: When forming a complex metallization system in which vias of different lateral size have to be provided, a split patterning sequence may be applied. For this purpose, a lithography process may be specifically designed for the critical via openings and a subsequent second patterning process may be applied for forming the vias of increased lateral dimensions, while the critical vias are masked. In this manner, superior process conditions may be established for each of the patterning sequences.

    摘要: In a replacement gate approach for forming high-k metal gate electrodes in semiconductor devices, a tapered configuration of the gate openings may be accomplished by using a tensile stressed dielectric material provided laterally adjacent to the gate electrode structure. Consequently, superior deposition conditions may be achieved while the tensile stress component may be efficiently used for the strain engineering in one type of transistor. Furthermore, an additional compressively stressed dielectric material may be applied after providing the replacement gate electrode structures.
