Noise and Reliability in Electronic Devices
As the devices scale down, even though the absolute noise magnitude gets smaller, since the voltages also scale down, the signal-to-noise ratio decreases. Noise models developed for large area devices based on the large-number-electron averaging theories break down. In addition, in sub-micron devices, as the device dimensions approach electron mean-free path, quantum effects start to play an important role. Since noise has important implications on the reliability and performance of the device, beyond a certain limit of scaling down, with existing models, it becomes impossible to predict the noise performance of an individual transistor, specifically a MOSFET. The lack of accurate models leads the process and circuit designer either to adapt large area-transistor models with high errors or to use a trial-and-error method leading to significant waste of valuable time. As the Semiconductor Research Corporation (SRC) has correctly concluded that there is an urgent need to measure, analyze, and model the noise characteristics of next generation sub-micron transistors.
Superconductive Devices
The primary objective of this project was to fabricate YBa2Cu3O7-x thin-film microbridges for the purpose of millimeter-wave detection and mixing. Reactive sputtering and hot oxygen jet sputter fabrication techniques were employed to produce high-quality YBa2Cu3O7-x thin-films. After the initial investigation of the composition, microstructure and the DC electrical properties, these films were patterned into variable thickness microbridges for millimeter-wave detection and mixing applications. Special emphasis was given to the repeatability of the fabrication process as it applied to the transition temperature, critical current, and noise properties.
Uncooled Infrared Detectors
A radiation detector is a device that produces an output signal, which depends on the amount of radiation hitting the active region of the detector. In general, infrared (IR) sensors can be classified as thermal or photon type of detectors. Photon type detectors such as photovoltaic or photoconductive sensors operate on the principles of direct electron - photon interaction. They provide superior sensitivity and response speed. However, photon detectors typically require costly cryogenic operation to minimize the noise sources to obtain the high relative sensitivity. On the other hand, thermal detectors convert incident radiation into heat, thereby raising the temperature of the detector element. This change in temperature is then converted to an electrical signal that can be amplified and displayed. Thermal detectors are capable of responding to a wide range of wavelengths without appreciable variation in responsivity. Thermal detectors display high sensitivity at room temperature to permit imaging and radiometry applications.
