The vast infrastructure of the microelectronic and microtechnological processing industry has yielded highly reproducible devices through reliable, reproducible, and fabrication-compatible processing techniques. Much development has occurred in bulk and surface micromachining, as well as in thin-film deposition techniques. Nevertheless, only a limited number of metrological applications have benefited from the use of this technology. Only two metrological applications that use microtechnology have been developed into commercially available devices: the JJA, as a DC reference, and the thermal RMS-to-DC converter, as an AC reference. Single electron tunneling devices and micromachined electrostatic RMS-to-DC converters are still under development. The accuracy requirements of the existing applications will continue to increase. This makes the development of on-chip references and on-chip self-test and self-calibration facilities essential. These microelectronic features, until now have remained unexploited in metrology, as well as in most other applications 相似文献

In this review/tutorial paper, we cover the history, physics, and current status of vacuum microelectronic devices. First we overview the performance requirements of vacuum microelectronic devices necessary for them to replace, or fill voids left by, solid state devices. Next we discuss the physical characteristics of micro-field-emission sources important to device applications. These characteristics include fundamental features, such as current-voltage data and noise, in addition to engineering considerations, such as life expectancy and procedures for tube assembly. We conclude with a review of a wide variety of demonstrated and proposed devices based on vacuum microelectronic principles, including electron guns, microwave tubes, and flat-panel displays 相似文献

Recent technical and market advances have created a resurgence of interest in miniature vacuum devices based on field-emission vacuum microelectronics. For several operational conditions, these new devices have inherent advantages over their solid-state counterparts. Vacuum microelectronic devices are less sensitive to temperature variations, provide high-speed switching capabilities, and are less susceptible to radiation damage. In addition, electron beams can be steered with external electric and magnetic fields, and electron devices are capable of operation with high current densities. In this article, we describe the development of this new generation of vacuum microelectronic devices and showcase some exciting applications arising from this technology, ranging from flat-panel displays to electron beam devices 相似文献

The success of III-nitride optoelectronic devices paths the way towards emerging devices in microelectronics. These devices are currently at the threshold to commercialization, therefore reliability considerations are becoming increasingly important. This paper reviews the material and process technology of III-nitride microelectronic devices in the scope of reliability. Since statistical reliability data are lacking in the current state of research the review starts with a summary of how reliability can be designed into process modules being relevant for microelectronic devices. This includes a discussion of the most important issues of material growth, metallization, implantation, dry etching and surface passivation. The subsequent chapter focuses to microelectronic devices and highlights technological challenges that have to be met in order to obtain reliable devices. Finally, results of lifetime experiments (thermal aging) demonstrate that III-nitride devices have the potential for reliable operation even at elevated temperatures up to 400°C. 相似文献
