    摘要: The optimization of a CMP process provides the use of an auxiliary layer (4) between a dielectric (1) in the vicinity of patterned portions and a layer of a liner (2). If the liner (2) is perforated in the CMP process, then the undercutting of the liner (2) by the chemical removal of the auxiliary layer (4) simplifies the process overall. Advantages are significantly lower defect densities due to CMP scratches, fewer short circuits, fewer alignment errors.

    摘要: A process for planarizing a process layer having structures and has been applied to a working surface of a semiconductor device, includes abrading the process layer down to the working surface using a polishing device. The working surface is planarized, and a defect density in the working surface is minimized and the polishing process is topology-independent.

    摘要: A method and apparatus of planarizing substrates is disclosed. A planarizing web medium is prepared for planarizing substrates to reduce defect generation. The planarizing web has a planarizing region and preparing region defined thereon, wherein at least one portion of the preparing region is outside the planarizing region. The web medium is advanced to move one portion of the web out of the planarizing region and another portion into the planarizing region.

    摘要: The invention describes a method for improving the readability of alignment marks on semiconductor wafers during multilayer metallization. Metal located in the alignment marks is etched back for the purpose of uncovering the edges of the alignment marks after the deposition of metal and subsequent CMP step. In the alternative, the oxide in the immediate vicinity of the alignment marks is etched back in a recess etching step until the metal in the alignment mark is partly uncovered.

    摘要: In one embodiment, an integrated circuit includes a memory array having a plurality of capacitors for storing data of an initial state in the memory array in an initial state. The integrated circuit also includes circuitry for occasionally inverting the data stored by the plurality of capacitors and tracking whether the current state of the data stored by the plurality of capacitors corresponds to the initial state. The circuitry inverts the data read out of the memory array during a read operation when the current state of the data does not correspond to the initial state.
