An SRAM device has STI regions separated by mesas and doped regions including source / drain regions, active areas, wordline conductors and contacts in a semiconductor substrate is made with a source region has 90 DEG transitions in critical locations. Form a dielectric layer above the active areas. Form the wordline conductors above the active areas transverse to the active areas. The source and drain regions of a pass gate transistor are on the opposite sides of a wordline conductor. Form the sidewalls along the <100> crystal plane. Form the contacts extending down through to the dielectric layer to the mesas. Substrate stress is reduced because the large active area region formed in the substrate assures that the contacts are formed on the <100> surfaces of the mesas are in contact with the mesas formed on the substrate and that the <110> surfaces of the silicon of the mesas are shielded from the contacts.

Methods for calibrating a photolithographic system are disclosed. A cold lens contour for a reticle design and at least one hot lens contour for the reticle design are generated from which a process window is defined. Aberrations induced by a lens manipulator are characterized in a manipulator model and the process window is optimized using the manipulator model.

Masks that include optical proximity correction or phase shifting regions are increasingly being used in the manufacturing process. These masks, either initially or after repair, can have “soft” defects, e.g. phase and / or transmission defects. In accordance with one feature of the invention, soft defect information can be computed from standard test images of a mask. This soft defect information can be used to generate an accurate simulated wafer image, thereby providing valuable defect impact information to a user. Knowing the impact of the soft defect can enable a user to make better decisions regarding the mask. Specifically, a user can now with confidence accept the mask for the desired lithographic process, repair the mask at certain critical locations, or reject the mask, all without exposing a wafer.

A two-vessel liquid separation apparatus includes a pump and its motor submersed in a one vessel and a reverse osmosis membrane in the other vessel. The vessels are separated by a contiguous dividing wall. The membrane and the pump are in fluid communication with one another through the dividing wall so as to allow liquid to pass from one vessel to the other in accordance with a given geometry. The pump receives liquid from the membrane containing vessel through holes in the dividing wall, the pump creating a highly turbulent flow caused by a cyclonic and co-axial effect, directly at the lower end of the membrane; the connexion of the pump outlet at the dividing wall is very close to the membrane thus providing an optimal efficiency of turbulence and flow at critical locations of bacteria collection. The injection of new liquid to be concentrated at the inlet of the pump causes an immediate mixture of liquid to be concentrated with concentrated liquid, which mixture circulates rapidly in a close circuit between the first and second vessels.

In a method of evaluating measured values for recognizing defect conditions due to material fatigue on aircraft parts, strain sensors (6) are applied on the critical locations of an aircraft (1) and measured values of outputs of the strain sensors are detected at different loading conditions, amplified and stored through several measuring circuits. An evaluating apparatus (9) derives, signals or indicates a material fatigue by comparison of current measured values with previous measured values. The critical aircraft parts (1) are impinged on with prescribed loading conditions by loading elements (3). The strain effect caused thereby is detected by measuring circuits. The evaluating apparatus (9) forms, for at least each loading condition and each measuring circuit, an allocated reference value and a permissible limit value range. If current measured values exceed the limit value range, this represents a material fatigue manifestation.

For bridges over waterways which are susceptible to scour, the load carrying capacity of the substructure may be reduced by scour. These bridges must be evaluated for reduced load rating and / or posting limits. Here, the substructure load rating is used in connection with calculating the bridge load rating. This is often limited by the substructure load carrying capacity and the tolerable deformation. Thus, bridges impacted by scour need to be judged based on both the superstructure and substructure components. The system / process to assess the substructure load rating uses an analytical method which combines numerical methods and empirical calculations to predict the behavior of a bridge's superstructure and substructure. Limited instrumentation is installed at critical locations on the bridge. The measurements are then used to verify and refine predictions to arrive at a substructure load rating which is usable with the superstructure load rating to define a safe load carrying capacity.

An electro-thermostatic expansion valve (ETXV) includes a valve body having a thermostatic actuator controlled by a Peltier thermoelectric module. The valve may be electronically controlled in response to measured parameters at critical locations in refrigeration, heating, pneumatic and hydraulic systems. A preferred method of controlling the ETXV valve involves the use of pressure or temperature sensors located on the expansion head of the ETXV or on an external device controlled by the ETXV. The sensors provide feedback signals to a micro-controller, and the micro-controller directly controls the thermoelectric module. An alternate method of controlling the new ETXV involves the use of operator inputs provided to a micro-controller which controls the thermoelectric module. The operator can manually adjust the micro-controller in response to observed process parameters. The ETXV can be configured to use one or both sides of the thermoelectric module to control the valve actuator.
