The design aspects of a V-groove vertical-geometry power MOST (VVMOS) using a simple epitaxial-channel technology, are discussed in this paper. The process has several features including ease of fabrication, good threshold voltage controllability, and high breakdown voltage. Expressions for the on-resistance as a function of device parameters and for the device capacitances as a function of the geometric features of the transistor are derived. Experimental results on fabricated devices are presented. 相似文献

Engineering devices based upon the interfacing of biological with inorganic systems have led to fascinating research results and present important implications for next‐generation technologies. The development of cell‐ and protein‐based micro/nano systems has demonstrated that several key factors must be considered when establishing fabrication rules. These include material interface properties, preserving biological viability, as well as self‐assembly as a device‐fabrication methodology, to name a few. Here, we present two proposed devices that have been developed through the application of these principles. They include muscle‐powered microfabricated devices, as well as protein‐functionalized polymeric vesicles based on protein‐coupling reactions. These systems have successfully bridged the gap between biological and conventional engineering to yield exciting prospects, as well as important lessons and questions for the development of cell‐/protein‐based hybrids. 相似文献

We report on 100-nm channel-length thin-film transistors (TFTs) that are fabricated using germanium-seeded lateral crystallization of amorphous silicon. Germanium seeding allows the fabrication of devices with control over grain boundary location. Its effectiveness improves with reduced device geometry, allowing “single-grain” device fabrication. In the first application of this technology to deep submicron devices, we report on 100-nm devices having excellent performance compared to conventional TFTs, which have randomly located grains. Devices have on-off ratio >106 and subthreshold slope of 107 mV/decade, attesting to the suitability of germanium-seeding for the fabrication of high-performance TFTs, suitable for use in vertically integrated three-dimensional (3-D) circuits 相似文献

提出了一种适用于按比例缩小至亚10nm的圆柱体全包围栅场效应管.报道了圆柱体全包围栅场效应管器件物理分析、技术仿真结果以及器件制作详细工艺流程.与其他常规鳍形场效应管器件(FinFET)相比,该器件特别适用于解决常规鳍形场效应管器件所面临的问题,进一步提高器件性能及按比例缩小能力.技术仿真结果显示,圆柱体全包围栅场效应管具备许多常规鳍形场效应管器件,其中包括长方体全包围栅场效应管所不具备的优点.就圆柱体全包围栅场效应管器件结构而言,该器件由无数多个将圆柱体形沟道全部包围的栅所控制.由于克服了由不对称场的积聚,如锐角效应所导致的漏电,器件沟道的电完整性得到很大改善.详细讨论了器件制作工艺流程,提出的工艺流程简单并且与常规CMOS工艺流程兼容. 相似文献
