离子注入金属材料表面改性 总被引:4,自引:0,他引:4
本文着重叙述了最近以来离子注入金属材料改性新的进展。离子注入金属的研究,其研究对象品种繁多,需要高注量,且样品形状复杂,因此离子注入金属中的物理问题比半导体离子注入更加复杂。包括各种离子注入多种金属所出现的溅射腐蚀、倾斜注入、特球形状注入、离子浓度分布、注入条件与金属相变的关系以及离子注入提高耐磨损机理等诸多难题。离子注入金属材料改性研究近年来极为活跃,已发表了不少评论文章。希望这篇评论能对从事离子束材料改性工作的人员有所帮助。 相似文献

通常人们对氮化硼薄膜的S掺杂,采用的是在氮化硼制备过程中就地掺杂的方法,文中则采用S离子注入方法. 氮化硼薄膜用射频溅射法制得. 实验结果表明,在氮化硼薄膜中注入S,可以实现氮化硼薄膜的n型掺杂;随着注入剂量的增加,氮化硼薄膜的电阻率降低. 真空退火有利于氮化硼薄膜S离子注入掺杂效果的提高. 在离子注入剂量为1E16cm-2时,在600℃的温度下退火60min后,氮化硼薄膜的电阻率为2.20E5Ω·cm,比离子注入前下降了6个数量级. 相似文献

The Ion Implanted Integrated Optics (I3O) technology, using titanium ion implantation in bulk silica to fabricate passive compact planar lightwave circuits (PLCs), is presented in this paper. Its advantages are described and compared with other waveguide fabrication technologies. It is demonstrated that the guided electromagnetic field can be tailored by adjusting the titanium ion dose either to fit the guided mode of standard single-mode fibers or to allow a sharp radius of curvature of bent waveguides. 相似文献

The correlated regularities of the variations in the structural and phase composition and morphological and field-emission characteristics of the surface-structured р- and n-Si crystals upon stepwise highdose ion-beam carbon processing are studied. It is shown that the stepwise high-dose ion implantation of carbon atoms into the surface of silicon wafers structured using nonlithographic carbon mask coatings makes it possible to reduce field-emission thresholds and increase the densities of the maximum field-emission currents by more than two orders of magnitude relative to the values for emitter arrays fabricated using traditional microelectronic technologies. The physicochemical mechanisms responsible for modifying the surface properties of silicon structures upon carbon ion implantation are discussed. 相似文献

Silicon bipolar transistors having cutoff frequencies from 40 to 50 GHz have been fabricated in a double -polysilicon self-aligned structure using a process which relies on ion implantation for the intrinsic base formation. The devices have nearly ideal DC characteristics, with breakdown voltages adequate for most digital applications. The results demonstrate that the performance limits of conventional implanted technologies are significantly higher than previously thought 相似文献

High-energy ion implantation is coupled with the conventional planar technology to realize a silicon FET for power application. This device known as "Gridistor" is a multichannel FET with a p-type buried as gate. Boron implantation at various energies (600-900 keV) through a metallic mask are used to do a high-doped p-type gate layer, 0.8 µ thick and buried 1 µ below the surface. Since there is no implantation induced defects in the active regions of the device, low annealing temperature can be effectively used. As a consequence, the pattern sharpness is only limited by the definition of the mask. Using ion-etched gold layer as mask, 1 µ wide channels are made in a reproductible way. Few test structures have been made to check the behavior of implantation and planar technologies by measuring their capaci tances, transconductance, and I-V characteristics. 相似文献

A microwave high-density plasma source is applied for room-temperature deposition of thin SiO2films, filling of submicron trenches, local planarization of the chip surface, etching of deep trenches in the insulator, and resist stripping after ion implantation. The structures obtained meet stringent demands for current technologies. Uniform processing of wafers up to 300 mm in diameter is demonstrated. 相似文献

Alternate approaches to obtain low-resistance, low-pressure chemical vapor deposition (LPCVD) WSi2 films for application as interconnections in silicon integrated circuit technologies were investigated. The silicide films were deposited on three different substrates and annealed in two different systems. The silicide films deposited on the doped substrates as well as films doped using ion implantation were analyzed. The silicide microstructure, electrical film conductivity, and dopant redistribution were studied as a function of the process variants. An optimum set of annealing conditions were identified that resulted in excellent silicide thin-film properties. A correlation between the material and electrical properties is provided using the experimental data 相似文献
