An optical proximity correction method is provided using a modified merit function based upon yield. Known failure mechanisms related to layout geometries are used to derive yield functions based upon distance values between layout features, such as, edge features. In comparing the edge points on the predicted layout pattern with the corresponding point on the design layout pattern, a yield test is first undertaken before movement of the points on the predicted layout pattern to a position of higher yield. Where yield is acceptable, no further movement is made. Where incremental movement of points results in coming within acceptable proximity before acceptable yield is reached, the point is flagged for further consideration.

A fluid assisted gas gauge coupled to a pressure sensor enables proximity measurements to be made with a high bandwidth. A two-chamber gas gauge, containing a gas-filled measurement chamber and a fluid-filled transfer chamber and a diaphragm separating the two chambers, exhausts gas onto the surface being measured, while the incompressible fluid transmits the pressure to a pressure sensor.

In addition, the incompressible fluid permits the pressure sensor to be remotely located from the point of measurement without sacrificing the response time performance. In an embodiment, a differential bridge version of the fluid assisted gas gauge reduces common mode effects.
