译者序 近年来真空微电子学的发展十分迅猛。去年七月在俄罗斯圣彼德堡召开的第九届国际真空微电子学会议 上有166篇论文发表,本文为这次大会的特邀报告。 值得注意的是几家即将把场发射显示器件(FED)推向市场的公司都没有发表有实质性内容的论文。这很可能是FED上市前的短暂沉寂和商业需要。FED究竟何时能够实现商品化?工作在GHz范围的场发射阵列(FEA)阴极何时能在射频功率放大器上得到实际应用?真空徽电子学又出现了哪些新技米和新的应用?等等,这些都是学术界和产业界十分关注的问题。 真空徽电子学权威之一,美国海军实验室的Henry F.Gray博士在本届国际真空徽电子学会议上的特邀报告中全面而概括地讨论了这些问题,对真空徽电子学的进一步发展作了谨慎的预见。他认为由于在科学技术土已没有明显的障碍,FED在一年内应能实现商品化。他还提出一个有趁的历史性问题:1948年开始了从真空君件到固态器件的过渡。在21世纪开端,我们能否看到从固态簇件到真空器件的回归呢?至少在策微电子学领域中的特殊应用场合是如此。1996年法国的PixTech及日本的Futaba公司终于向世界发布了5 .2英寸FED的商品广告,从而将FED推向市场,将预告1997年将推出8.5英寸的VGA级全彩色FED。这证实了Henry博士预见的准确性,预示了FED繁
In recent years, the development of vacuum microelectronics is very rapid. Last July, at the Ninth International Vacuum Microelectronics Conference held in St. Petersburg, Russia, there were 166 papers published, this article is a special report of the conference. It is noteworthy that several companies that are about to launch their field-emitting display devices (FEDs) on the market do not publish substantively dissertated papers. This is likely to be a brief silence and business need before the FED goes public. When does FED commercialize? Field Emission Array (FEA) working in the GHz range Can the cathode be put to practical use on a RF power amplifier? What are the new technologies and new applications in vacuum electronics? These are all issues of great concern to academia and industry. Vacuum emblem electronics one of the authority, the United States Naval Laboratory, Dr. Henry F. Gray in the current International Conference on the issue of vacuum emblem invited a comprehensive and general discussion of these issues, the further development of electronic emblem vacuum Made a cautious forecast. He thinks the FED should be commoditized within a year because there are no obvious obstacles in science and technology. He also proposed a historic issue that took advantage of the fact that in 1948 the transition from a vacuum monarch to a solid state device began. At the beginning of the 21st century, can we see the return from solid-state clusters to vacuum devices? At least for special applications in the field of microelectronics. In 1996, PixTech in France and Japan’s Futaba finally released 5.2-inch FED commercials to the world, bringing the FED to market. It is forecasted that the 8.5-inch VGA full-color FED will be introduced in 1997. This confirms the accuracy foreseen by Dr. Henry and heralds FED multiplication
