    Abstract: A self-modifying FPGA system includes an FPGA and a configuration memory coupled to the FPGA for providing the FPGA with configuration data including SAFE configuration data and dormant configuration data. The SAFE configuration data is initially loaded to the FPGA and the FPGA is configured to a safe operating mode. Upon a determination to proceed to a next step of self modification, dormant configuration data contained in the configuration memory is loaded into the FPGA and the FPGA is configured to a secure operating mode.

    Abstract: A system and method for creating a graphical program. A function block may be displayed in a graphical program. The graphical program may include a plurality of interconnected blocks which visually indicate the functionality of the program. Additionally, the function block may be operable to perform a first function and may include one or more inputs and one or more outputs. User input specifying an attribute behavior for the function block may be received, e.g., via a menu which allows selection or definition of attribute behaviors, a graphical wizard, or another graphical program, among other methods. The attribute behavior specified for the function block may be usable to determine at attribute of at least a subset of the one or more outputs of the function block based on an attribute of at least one of the one or more inputs to the function block.

    Abstract: A method and apparatus provides for high-speed switching of high-voltage and high power MOSFET-based solid state relays. A driver for a MOSFET based, high voltage, high current electronic relay includes a current supply for actuating the switching circuit and a transformer arrangement coupled to the current supply for receiving the supply of current from the current supply. The transformer arrangement is adapted for coupling with the switching circuit for selectively applying a predetermined voltage to the switching circuit which establishes the switching circuit in switch conducting or switch isolation.

    Abstract: A novel low metal ion developer composition used in a two step process which provided high contrast images and long developer bath life is provided. The process gives high contrast images. The substrate coated with positive photoresist is exposed then immersed in a "predip" bath, rinsed, and then, immersed in the developer bath, rinsed and dried. This process provided high contrast which does not decrease over the life of the developer system. The system consists of (1) a predip solution containing aqueous non-metal ion organic base and a cationic surfactant adjusted to a concentration that does not give development, and (2) a developer solution containing an aqueous solution of an non-metal ion organic base and a fluorochemical surfactant adjusted to a concentration that provides development. The high contrast is achieved by the cationic surfactant coating the resist and inhibiting the attack on the unexposed resist by the developer while permitting the developer to dissolve away the exposed resist.

    Abstract: A positive photoresist metal ion aqueous developer is provided that gives a high contrast to the photoresist.The developer disclosed comprises a formulation of aqueous alkali-base such as potassium hydroxide and a carboxylated surfactant. The incorporation of the carboxylated surfactant provides the unexpected increase in the contrast of the photoresist. The addition of the carboxylated surfactant increases the gamma from a typical photoresist gamma (.gamma.) of 3 or less to a gamma greater than 5.The high contrast photoresist provides linewidth control and affords improved process latitude in photoresist imaging. The linewidth control is particularly critical in cases where fine lines are to be defined in the resist that covers steps of topography on the coated substrate. The higher the contrast, the less affected the resist by the topography, provided the exposure is adequate to expose the resist. The process latitude afforded by the high contrast is a result of the ability to over develop (develop longer) the exposed resist without affecting the unexposed resist in the adjacent areas.
