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.

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.
