In this thesis, basic manufacturing processes and techniques for integrated ferroelectrics, such as thin film deposition and film patterning, have been studied. Based on these studies, lead zirconate titanate ferroelectric thin film, which has higher piezoelectric constant than normal piezoelectric materials, is used in silicon-based piezoelectric miniature microphone.

The energetic and structural properties of SiH_2 adsorbed on single dimer vacancy of the Si(100)-c(4×2) surface, the structures of 0.5ML hydrogenated Si(100) surface and the deposition and diffusion behaviours of silicon adatom on the H-terminated Si (100) surfaces have been studied by using empirical tight-binding total energy calculations.

The adsorptions of SiH_2, SiH_2 with a hydrogen adatom (SiH_2+H) and SiH_2 with two hydrogen adatoms (SiH_2+2H) on the Si (100) surface near SDV structure have been calculated. Three possible sites are found in each case, and the presenting of hydrogen may reverse the relative stability of these sites.

本文首先计算分析了SiH_2、SiH_2+H和SiH_2+2H等硅烷分解后的产物在硅表面的吸附特性，我们发现每种情况都有三个可能吸附的位置，并且表面附着氢原子的出现可以造成这些吸附位置相对稳定性的逆转。

Based on the above research, we analyzed regional metallogenic conditions from geology, geophysics and geochemistry. Considering regional strata, some source beds with ore-bearing strata controlled apparently metallogenesis. The strata contained hydrothermal siliceous rock or siliceous albitite ether formed some favorable source beds and established substantial foundation for later diplogenetic metallogenesis e.g.

从区域地层上来看，含特殊层位的矿源层对成矿有明显的控制作用，其中含热水沉积成因的硅质岩或硅质钠长质岩的地层或形成有利的矿源岩，为后期叠生成矿奠定物质基础，或直接形成工业矿床；另外，区内黑色页岩（包括碳质板岩、碳质泥岩、碳质页岩和含碳钙质板岩等）也是很好的矿源层。

Several conclusions are drawn from the study. The ore deposit mainly occurs in the lower Cambrian Shuigoukou Formation, which is situated at the limbs of Qingshixia-Yujiatai overturned multiple syncline. The ore-hosted rocks are silicalite and mudstone. The content of SiO2 is high in the rocks of V ore deposit. Silicalites are mainly aphanitic quartz and chalcedony and the barite is sedimentogenic. The correlation between V and Cr, U, Ba is good. The rare earth element distribution patterns show Ce-negative or positive anomaly, obviously Eu positive anomaly and the right dip graphics.
