  • Patent number: 7251188
    Abstract: A memory access interface for connecting a memory to a micro-controller having an address/data multiplexing bus and a microprocessor is proposed. The memory access interface includes an address latch, a multiplexer, and a data buffer. The address latch latches and outputs the lower-bit address signal on the address/data multiplexing bus of the micro-controller when an address-latch-enable signal is enabled. The multiplexer receives the lower-bit address signal latched by the address latch, a higher-bit address signal outputted from the micro-controller, and an address signal outputted from the microprocessor and selectively outputs the address signal of the micro-controller or the address signal of the microprocessor as the address signal of the memory according to a first control signal.

  • Patent number: 6997664
    Abstract: The present invention proposes an apparatus for loading and unloading wafers to and from the semiconductor fabrication equipment. The present invention uses two U-shaped port plate supporters of high rigidity to respectively join with drive devices such as lead screws, shaft bearings, and a lead device, and then join with components such as a port plate, a port door, and a base. The assembly is driven by a motor via timing pulleys, timing belts, idle wheels, a pair of lead screws, shaft bearings, and a lead device. An encoder is matched for feedback control. Thereby, accurate positioning of the main mechanism of the wafer pod responsible for upward and downward movement can be achieved so as to increase the accuracy and reliability of positioning transfer of wafers. Secondarily, the contamination of particles resulted from the motion of the main mechanism can be reduced by using an intake filtering system.
