VERTICAL CONVOLUTE METAL BELLOWS FOR ROTARY MOTION, VACUUM SEALING, AND PRESSURE SEALING
A system and method for rotary motion with vacuum sealing is provided. The system includes a vacuum chamber, a component mount disposed in the vacuum chamber, and a base. A bellows is disposed between the base and the component mount, and the bellows provides a seal between the base and the component mount. The bellows, the base, and the component mount define an actuator compartment therebetween. An actuator is disposed in the actuator compartment. The actuator is configured to rotate the component mount relative to the base in order to align a component disposed on the component mount. Rotation of the component mount relative to the base causes torsional elastic deformation of the bellows.

Wafer metrology technologies
Various approaches can be used to interrogate a surface such as a surface of a layered semiconductor structure on a semiconductor wafer. Certain approaches employ Second Harmonic Generation and in some cases may utilize pump and probe radiation. Other approaches involve determining current flow from a sample illuminated with radiation. Decay constants can be measured to provide information regarding the sample. Additionally, electric and/or magnetic field biases can be applied to the sample to provide additional information.
Waveguide integrated circuit testing
A structure and method for providing a housing which includes a high frequency (HF or RF) connection between a device under test (DUT) having a waveguide 22.

Terahertz Plasmonics for Testing Very Large-Scale Integrated Circuits under Bias
Various embodiments are described that relate to failure determination for an integrated circuit. An integrated circuit can be tested to determine if the integrated circuit is functioning properly. The integrated circuit can be subjected to a specific radiation such that the integrated circuit produces a response. This response can be compared against an expected response to determine if the response matches the expected response. If the response does not match the expected response, then the integrated circuit fails the test. If the response matches the expected response, then the integrated circuit passes the test.
