寒 假 DIARY On January 19, I went to the railway station in advance, there are lots of people see the train station, the appearance of the very lively;Waited for two hours, finally got on the train and sat on the bench, surrounded by strangers, no words, I and the other side of the fat man cross -eyed, tired to sleep, wake up and eyes, soon in shiyan city, hubei province. On January 22nd, in idle to nothing, and I always want to find something to do, so I just find a not high not short began to climb the mountain, the mountain road, had to open myself, all the way thorns, and I climbed to the top of the mountain, at the top of the hill in the sunshine is very comfortable, discovered has looked around the road.Then went down the mountain easily. DIARY On January 30, I was originally going to shenzhen with my parents for the holiday, but due to traffic inconvenience, this year the brother-in-laws side, the whole family around the brazier to watch the annual Spring Festival gala, at 24 o clock, everyone began to set off firecrackers and fireworks, soon in the inky sky bright blooming flowers, very beautiful. On February 4, open the window a look after I get up in the morning, was a vast expanse of whiteness outside the mountain to take care of all want to wear wedding dress the bride;Yes, last night of snow, the power of nature is infinite, overnight, he will be able to change your world.Snow is large enough, a layer also paved the thick on the ground, so I took two children together for a snowman, although very cold hands, but very happy. DIARY On February 10, how fast time flies, the winter vacation is almost over a month, and going back to school, the school is looking forward to have a holiday, the holiday soon, and looking forward to back to school, to school, and sighed with emotion holiday is too short, why do people always are in conflict? 微电子学 微电子学是研究在固体（主要是半导 体）材料上构成的微小型化电路、电 路及系统的电子学分支。 作为电子 学的分支学科，它主要研究电子或粒 子在固体材料中的运动规律及其应用 ，并利用它实现信号处理功能的科学 ，以实现电路的系统和集成为目的， 实用性强。微电子学又是信息领域的 重要基础学科，在这一领域上，微电 子学是研究并实现信息获取、传输、 存储、处理和输出的科学，是研究信 息获取的科学，构成了信息科学的基 石，其发展水平直接影响着整个信息 技术的发展。微电子科学技术的发展 水平和产业规模是一个国家经济实力 的重要标志。 微电子学是一门综合 性很强的边缘学科，其中包括了半导 体器件物理、集成电路工艺和集成电 路及系统的设计、测试等多方面的内 容；涉及了固体物理学、量子力学、 热力 学与统计物理学、材料科学、电子线 路、信号处理、计算机辅助设计、测 试和加工、图论、化学等多个领域。 微电子学是一门发展极为迅速的学科 ，高集成度、低功耗、高性能、高可 靠性是微电子学发展的方向。信息技 术发展的方向是多媒体（智能化）、 网络化和个体化。要求系统获取和存 储海量的多媒体信息、以极高速度精 确可靠的处理和传输这些信息并及时 地把有用信息显示出来或用于控制。 所有这些都只能依赖于微电子技术的 支撑才能成为现实。超高容量、超小 型、超高速、超高频、超低功耗是信 息技术无止境追求的目标，是微电子 技术迅速发展的动力。 微电子学渗透 性强，其他学科结合产生出了一系列 新的交叉学科。微机电系统、生物芯 片就是这方面的代表，是近年来发展 起来的具有广阔应用前景的新技术。 微电子技术是高科技和信息产业的核心技 术。微电子产业是基础性产业，之所以发展得 如此之快，除了技术本身对国民经济的巨大贡 献之外，还与它极强的渗透性有关。另外，现 代战争将是以集成电路为关键技术、以电子战 和信息战为特点的高技
