US Classification:

382145, 382151, 382168

Abstract:

An image of a semiconductor interconnection pad is analyzed to determine a geometric description of the zone regions of a multiple zone semiconductor interconnection pad. Edge detection machine vision tools are used to extract features in the image. The extracted features are analyzed to derive geometric descriptions of the zone regions of the pad, that are applied in semiconductor device inspection, fabrication, and assembly operations.

International Classification:

G01C 21/00

US Classification:

701214, 34235708

Abstract:

A first navigation unit of an apparatus in one example comprises a hybrid global positioning system (GPS)/inertial navigation system (INS) component. The hybrid GPS/INS component provides first GPS information and first INS information for the first navigation unit. The first navigation unit is configured to receive second GPS information and second INS information from a second navigation unit. The second navigation unit comprises a GPS component configured to determine a double-differenced GPS carrier phase measurement through employment of the first GPS information and the second GPS information. The first navigation unit comprises a relative Kalman filter configured to update an INS error estimate for an estimate of a relative position between the first and second navigation units based on the double-differenced GPS carrier phase measurement and the first and second INS information.

Abstract:

A multi-level lithography processes for the fabrication of suspended structures are presented. The process is based on the differential exposure and developing conditions of several a plurality of resist layers, without harsher processes, such as etching of sacrificial layers or the use of hardmasks. These manufacturing processes are readily suited for use with systems that are chemically and/or mechanically sensitive, such as graphene. Graphene p-n-p junctions with suspended top gates formed through these processes exhibit high mobility and control of local doping density and type. This fabrication technique may be further extended to fabricate other types of suspended structures, such as local current carrying wires for inducing local magnetic fields, a point contact for local injection of current, and moving parts in microelectromechanical devices.
