  • Patent number: 6259058
    Abstract: An apparatus for physically separating non-metallic substrates by forming a microcrack in the substrate and controlling propagating the microcrack. An initial mechanical or pulsed laser scribing device forms a microcrack in the substrate. If a pulsed laser is used, it forms a crack in the substrate between its top and bottom surf. A scribe beam is applied onto the substrate on a separation line. A helium coolant stream intersets with, or is adjacent to, the trailing edge of the scribe beam. The temperature differential between the heat affected zone of the substrate and the coolant stream propagates the microcrack. Two breaking beams on opposing sides of the separation line follow the coolant stream. The breaking beams create controlled tensile forces that extend the crack to the bottom surface of the substrate for full separation. The scribe and break beams and coolant stream are simultaneously moved relative to the substrate. A preheat beam preheats the heat affected area on the substrate.

  • Patent number: 6211488
    Abstract: An apparatus and method for physically separating non-metallic substrates forms a microcrack in the substrate and controllingly propagates the microcrack. An initial mechanical or pulsed laser scribing device forms a microcrack in the substrate. If a pulsed laser is used, it forms a crack inside the substrate that does not extend to either the upper or lower surface. A scribe beam is applied onto the substrate on a separation line. A coolant stream intersects with, or is adjacent to, the trailing edge of the scribe beam. The temperature differential between the heat affected zone of the substrate and the coolant stream propagates the microcrack. Two breaking beams on opposing sides of the separation line follow the coolant stream.

  • Patent number: 6071809
    Abstract: Dual damascene methods and structures are provided for IC interconnects which use a dual-damascene process incorporating a low-k dielectric material, high conductivity metal, and an improved hard mask scheme. A pair of hard masks are employed: a silicon dioxide layer and a silicon nitride layer, wherein the silicon dioxide layer acts to protect the silicon nitride layer during dual damascene etch processing, but is subsequently sacrificed during CMP, allowing the silicon nitride layer to act as a the CMP hard mask. In this way, delamination of the low-k material is prevented, and any copper-contaminated silicon dioxide material is removed.

  • Patent number: 6055024
    Abstract: An adaptive method and system for processing luma and chroma signals from lines of a video signal. The invention includes an adaptive comb filtering algorithm that determines whether to average lines of video data based on the signal content. If two lines are dissimilar, a simple notch/bandpass system is used. The invention provides improved adaptive comb filtering performance at vertical transitions between high-luminance-detail areas and between other areas such as solid colors or flat gray or white fields by dynamically determining whether to average the chrominance information of the current video line with the chrominance information of the previous line, next line, both of such lines, or neither of such lines.

  • Patent number: 6014622
    Abstract: A pitch lag coding device and method using interframe correlation inherent in pitch lag values to reduce coding bit requirements. A pitch lag value is extracted for a given speech frame, and then refined for each subframe. For every speech frame having N samples of speech, LPC analysis and vector quantization are performed for the whole coding frame. The LPC residual obtained for each frame is then processed such that pitch lag values for all subframes within the coding frame are analyzed concurrently. The remaining coding parameters, i.e., the codebook search, gain parameters, and excitation signal, are then analyzed sequentially according to their respective subframes.
