The planarization technology of Chemical-Mechanical-Polishing (CMP), used for the manufacturing of multi- level metal interconnects for high-density Integrated Circuits (IC), is also readily adaptable as an enabling technology in MicroElectroMechanical Systems (MEMS) FABRICATION, particularly polysilicon surface micromachining. CMP not only eases the design and manufacturability of MEMS devices by eliminating several photolithographic and film issues generated by severe topography, but also enables far greater flexibility with process complexity and associated designs.

The mature CMOS FABRICATION processes are available in many IC foundries. It is cost-effective to leverage the existing CMOS FABRICATION technologies to implement MEMS devices. On the other hand, the MEMS devices could also add values to the IC industry as the Moore’s law reaching its limit. The CMOS MEMS could play a key role to bridge the gap between the CMOS and MEMS technologies. The CMOS MEMS also offers the advantage of monolithic integration of ICs and micro mechanical components.

Thanks to the advances in micromachining FABRICATION technologies and significant cost reduction due to mass production, miniature sensors of angular rate, or gyroscopes, found their way into the everyday life of every user of modern gadgets, such as smart phones, tablets or even wristwatches. Often without realising, many of us are carrying in our pockets fully equipped with all necessary sensors complete inertial navigation systems that not so long ago were available only for advanced vehicles in sea, land, air or space. Accelerometers and gyroscopes are found in specifications of any gadget supposed to react to user movements. And one of the most commonly used type of gyroscopes used to developed these systems is Coriolis vibratory gyroscope (CVG).

For more than three decades, Micro Electro Mechanical Systems (MEMS) have steadily transitioned out of research labs and into production forming a more than $10 billion market [1]. MEMS devices such as accelerometers, pressure sensors and microphones, to name a few, have seen immense utilization, particularly in the consumer electronics market, because of their compact sizes and minute power consumptions. In addition, these devices benefit from batch FABRICATION, which has enabled year-over-year reductions in cost [2]. In recent years,

Micro-Electro-Mechanical Systems (MEMS) are miniature systems composed ofintegratedelectricalandmechanicalpartstosenseand/orcontrolthingsonaμmscale. The concept of MEMS is attributed to Richard Feynman’s famous talk on December 29th, 1959 [2,3]. Dr. Feynman foresaw many aspects of future MEMS development with his insight in microphysics.

FPGA開發全攻略-工程師創新設計寶典-基礎篇+技巧篇-200頁第一章、為什么工程師要掌握FPGA開發知識？作者：張國斌、田耘2008 年年初，某著名嵌入式系統IT 公司為了幫助其產品售后工程師和在線技術支持工程師更好的理解其產品，舉行了ASIC/FPGA 基礎專場培訓．由于后者因為保密制度而只能接觸到板級電路圖和LAYOUT，同時因ASIC/FPGA 都是典型的SoC 應用，通常只是將ASIC/FPGA 當作黑盒來理解，其猜測性讀圖造成公司與外部及公司內部大量的無效溝通．培訓結束后, 參與者紛紛表示ASIC/FPGA 的白盒式剖析極大提高了對產品的理解，有效解決了合作伙伴和客戶端理解偏異性問題，參加培訓的工程師小L 表示：“FPGA 同時擁有強大的處理功能和完全的設計自由度，以致于它的行業對手ASIC 的設計者在做wafer FABRICATION 之前, 也大量使用FPGA 來做整個系統的板級仿真，學習FPGA 開發知識不但提升了我們的服務質量從個人角度講也提升了自己的價值。”實際上，小L 只是中國數十萬FPGA 開發工程師中一個縮影，目前，隨著FPGA 從可編程邏輯芯片升級為可編程系統級芯片，其在電路中的角色已經從最初的邏輯膠合延伸到數字信號處理、接口、高密度運算等更廣闊的范圍，應用領域也從通信延伸到消費電子、汽車電子、工業控制、醫療電子等更多領域，現在，大批其他領域的工程師也像小L 一樣加入到FPGA 學習應用大軍中。未來，隨著FPGA 把更多的硬核如PowerPC? 處理器等集成進來，以及采用新的工藝將存儲單元集成，FPGA 越來越成為一種融合處理、存儲、接口于一體的超級芯片，“FPGA 會成為一種板級芯片，未來的電子產品可以通過配置FPGA 來實現功能的升級，實際上，某些通信設備廠商已經在嘗試這樣做了。”賽靈思公司全球資深副總裁湯立人這樣指出。可以想象，未來，FPGA 開發能力對工程師而言將成為類似C 語言的基礎能力之一，面對這樣的發展趨勢，你還能簡單地將FPGA 當成一種邏輯器件嗎？還能對FPGA 的發展無動于衷嗎？電子
