    Abstract: An optoelectronic transceiver that has integrated optical and electronic components, and can be passively aligned by a flip-chip method and a mechanical method is provided. The optoelectronic transceiver can be constructed by the key components of a circuit board, a silicon sub-mount, at least two IC chips formed on a silicon sub-mount, a microlens array, an optical fiber, and a receptacle for housing the silicon sub-mount, the at least two IC chips, the microlens array and the optical fiber connector in an aligned configuration. The at least two IC chips preferably include a laser diode, a laser diode driver, a photodetector and a photodetector amplifier. The mechanical alignment between a microlens array and a silicon sub-mount is performed by indentations provided in the surfaces of the two parts and the placement of spacer balls in the indentations.

    Abstract: An IC die formed with built-in stress test pattern and a method for forming such pattern are described. The stress test pattern may be formed by first forming a thermal oxide insulation layer on a silicon substrate, then forming a first plurality of diagonally positioned linear metal traces of a first metal, then depositing an electrically insulating material layer on top of the first plurality of diagonally positioned metal traces, and forming a second plurality of L-shaped metal bars of a second metal positioned with the two sides of L parallel to the two sides of a corner region and overlapping the first plurality of metal traces with the electrically insulating material layer therein between. The double metal method for forming the stress test pattern can be easily incorporated into the fabrication process for an IC die without any additional deposition or photolithographic steps. The metal 1 and metal 2 layers may be suitably formed of aluminum or an aluminum alloy, or any other conductive metallic material. The L-shaped metal bars formed by the metal 2 layer should intersect the linear metal traces at a 45° angle with an isolation layer therein between. An electrical resistance between the two metal layers can be determined by a leakage current therein between as a direct indication of the thermo-mechanical stresses, or shear stresses existing between the two metal layers. The present invention stress test pattern can be formed in any size or dimensions as long as one metal layer is formed in linear, diagonal strips while the other metal layer is formed in L-shaped metal bars overlapping the first metal layer.

    Abstract: A switchable I/O buffer for multi-chip modules comprising a conventional I/O buffer and a miniaturized I/O buffer. A path switch selects the conventional I/O buffer or the minaturized I/O buffer according to whether the I/O interconnection is for communication off the module or chip-to-chip communication within the module. The miniaturized I/O buffer comprises a single-ended I/O buffer without electrostatic discharge protection. Two layout structures are designed for the switchable I/O buffer. A first layout structure having its path switching control provided by either a cell-programmable method or a mask-programmable method can be used for a multi-chip module or a PWB single package. A second layout structure using a pad-programmable method to provide the path switching control is suitable for a multi-chip module with flip-chip attachment technology. Four different circuit implementations of the switchable I/O buffer are presented. The switchable I/O buffer achieves higher performance with lower power dissipation in that the unnecessary heavy loading and electrostatic discharge protection are eliminated from the interconnection for chip-to-chip communication within the multi-chip module.

    Abstract: The present invention provides a register-indirect addressing mode using modulo arithmetic to transpose addresses for digital processing systems. The preferred systems and methods permit direct access of column data, which improves matrix computation significantly. The overhead of transpose mode is minimal because it can be implemented, if desired, by sharing hardware and/or software used in circular buffers. Transpose addressing mode also reduces program size and processor power consumed by reducing the sequence of instruction cycles.

    Abstract: Automatic alignment methods for a membrane prober are disclosed. Alignment patterns are designed and manufactured on both a membrane prober and a wafer under test. The patterns are properly designed for acquiring a first set of measurement data that provide relative position information when the prober contacts the wafer. A second set of measurement data can be obtained by a controlled move between the prober and the wafer. The relative position including the translation offset and the rotation angle can be computed by the information derived from the two sets of measurement data. The second set of measurement data may also be acquired by having two alignment pattern pairs that are made to contact in a single touch. More accurate alignment can be achieved by using more pairs of alignment patterns.
