    Abstract: To prevent a furnace in a semiconductor process from temperature and gas excursion, a paddle and spike thermal couples arranged on the sidewall of the tube and adjacent to the heater, respectively, are connected to a temperature controller to regulate the heater, and a mass controller adjusts the gas flow injected to the tube. In the method, the spike thermal couple, peddle thermal couple and zero point of the mass flow controller are checked to maintain within a first and second temperature ranges and a first gas flow speed range, respectively, and after wafers are loaded and temperature is ramped up, the peddle thermal couple and mass flow controller are checked again to maintain within a third temperature range and second gas flow speed range.

    Abstract: A method for producing a circuit layout comprising the steps of establishing high-level input parameters which identify input/output characteristics and high-level functional parameters of a data path, inputting the input parameters to a compiler, the compiler performing steps of creating a data path netlist by selecting data path components in response to the established high-level input parameters; and automatically selecting control logic for the data path components. The data path netlist is a high-level netlist of Boolean logic which can then easily be translated into a gate level implementation of the circuit layout.
