硬性底片 的英文怎麼說
中文拼音 [yìngxìngdepiān]
硬性底片
英文
hard film-
In this paper, plasma - enhanced chemical vapor deposition ( pecvd ) technique was used to deposit the dielectric p - sio2 films and p - sion films on the silicon wafer under the conditions of low temperature and low pressure with teos organic sourse. this research was focused on the evaluation of film growth, hardness, stress, resistance and refractive index, by changing the experimental parameters including rf power, substrate temperature, chamber pressure, and the flow rates of teos, o2, n2. the results showed that the p - sio2 film was smooth, dense, and structurally amorphous
實驗結果顯示，用pecvd法淀積的p - sio _ 2膜是一表面平坦且緻密的非晶質結構的薄膜，與矽片襯底之間有良好的附著性；在中心條件時生長速率可控制在2600a / min左右；在基板溫度410時有最大的硬度可達16gpa ；其應力為壓縮應力，可達- 75mpa ；薄膜的臨界荷重為46 . 5un 。Firstly, i introduce the hardware and software platform of embedded system, and explain the basic hardware and software development, it ’ s a cooperate process. then i analyse the cross development method for embedded system, mentioned the “ host ” and “ target ” in the development of an embedded system. take e - book project as an example, follows the process to introduce a real embedded system project, including the mcu, periphery hardware and the integrated development environment which can provide the whole platform for an integrated development on the pc - - wb33. then i present 3 of the hardware of e - book. for lcd, i introduce the common feature of lcd, the ssct lcd as well as the design, actualize of its driver. for the rs232 serial port, the principle of the serial port and the main driver of it are introduced. for flash memory, i introuce the principle of nor flash and nand flash, and how their drivers implemented. in the end, the conclusion of this paper is generated, there is also a prospect for further research
