A data processing system implementing a service-oriented architecture that efficiently provides for self-directed communications between service requesters and service providers. Service providers, operative to implement a predefined computing functions, are responsive to first service requests and operative to provide a first service responses. Service requesters executed remote from service providers are operative to provide second service requests and receive second service responses. A service invocation framework local to each service requester functions to convert between first and second service requests and first and second service responses and to establish direct invocation communications connection with a selected service provider for the exchange of first service requests responses. A service invocation manager provides configuration meta-data, upon dynamic request by a service invocation framework, to define the conversions and communications connection to be implemented by the service invocation framework with respect to a service provider.

Sheet resistance, junction leakage and contact conductivity of a semiconductor layer, associated with an ultra-shallow junction layer or metal film are measured by contacting the surface with a plurality of probes. The probes can be used, in conjunction with a four-point probe system, to determine sheet resistivity. Junction leakage through an ultra-shallow junction is determined by establishing a reverse bias across the junction set at a predetermined voltage value, measuring through a first probe a total junction current conduction value, measuring through second, third, and fourth probes a plurality of voltage values. The junction leakage value is then directly computed based on the sheet resistivity value, reverse bias potential, wafer radius, and the measured voltage values. Contact conductivity between a metal film and semiconductor layer can be similarly directly computed.

Leak rate testing is an engineering challenge where on the one hand, engineers must meet strict leak rate standards on a wide range of products and systems from semiconductor packages through medical product packaging to chemical storage vessels and liquid/gas handling systems. On the other hand, they have to make the leak testing process low cost and independent of operator whilst in many applications making the process automated and fast as this step may otherwise become a manufacturing bottleneck. Accordingly embodiments of the invention address manufacturing requirements by providing for high accuracy flow based leak testing of large volumes, providing adaptive techniques for use during testing, providing equivalent circuit modeling techniques allowing optimization and parameter extraction to be simulated prior to manufacturing commitment, and providing for the automatic tuning of setup parameters.
