  • Patent number: 6949416
    Abstract: Disclosed is a technique capable of enhancing the degree of freedom in the layout of a rerouting layer in a wafer level CSP in which defect repairing is performed by cutting a fuse. More specifically, after the defect repairing is performed by irradiating a laser beam to a fuse, an organic passivation layer (photo-sensitive polyimide layer) is filled in a fuse opening. Thereafter, a rerouting layer, a bump land, an uppermost wiring layer, and a solder bump are formed on the organic passivation layer. In the following steps of the defect repairing, the baking process to cure an elastomer layer and the uppermost protection layer is conducted at a temperature below 260° C. in order to prevent the variance of the refresh times of memory cells.

  • Patent number: 6911348
    Abstract: A device and a method for determining the extent of an at least locally lateral undercut of a structured surface layer on a sacrificial layer. The structured surface layer for this purpose locally has at least one passive electronic component, using which a physical measured quantity can be determined, which is proportional to the extent of the lateral undercut. The method for generating this device proposes, initially on the structured surface layer in a first etching method, to provide the surface layer at least locally with a structuring having trenches and, in a second etching method, proceeding from the trenches, to undertake at least locally a lateral undercut of the structured surface layer. In this context, in the first etching method on the surface layer, locally at least one passive electronic component is additionally delineated out, which in response to a subsequent undercutting of the surface layer is also undercut.

  • Patent number: 6773158
    Abstract: In a method apparatus for measuring the temperature of a semiconductor substrate during processing thereof in a processing chamber, a resonant circuit formed on the substrate surface is energized by an electromagnetic field radiation device, and disturbances in the electromagnetic field are detected to determine the resonant frequency of the resonant circuit. The temperature of the substrate is determined as a function of the resonant frequency. The substrate is moved into and out of processing chamber by a transfer arm, and the radiation device is disposed on the transfer arm or mounted on the processing chamber. Multiple resonant circuits may be provided, which are energized by movement of the transfer arm, without transferring the substrate.

    Abstract: A transfer recording material allowing the production of customized holographic images is described. The transfer recording material comprises a multilayer structure on a carrier forming a plurality of panels. A portion of the multilayer structure corresponding to a panel comprises an embossable layer (holographic layer) wherein each pixel is configured to reflect incoming light at a predetermined angle #1. Each pixel corresponding to the embossable layer of an adjacent panel is configured to reflect incoming light at a different predetermined angle #2. The transfer recording material can have as many panels as desired by a particular application, each of the layers having an embossable layer with pixels configured to reflect incoming light at a certain angle #. The transfer material is therefore formed by a plurality of spaced-apart panels each of which comprises an embossable holographic layer reflecting light at a predetermined angle different from that of other panels.

    Abstract: A method and system can compensate for anneal non-uniformities by implanting dopant in a pattern to provide higher dopant concentrations where the anneal non-uniformities result in lower active dopant concentrations. A pattern for the anneal non-uniformities may be determined by annealing a wafer having a uniform dopant distribution and measuring properties of the wafer after annealing, e.g., by obtaining a sheet resistance map of the wafer. In one embodiment, the non-uniformities may be measured by measuring temperature variations during annealing.
