fSocial capital is a theory that attempts to describe features of the fabric of society. It identifies factors in populations such as the level of civic participation, social networks, and levels of trust because such forces shape the quality and quantity of social interactions and institutions that underpin society. Two questions have dominated the literature: can social capital prevent or cause mental illness, and does the level or type of social capital have an impact on the rate of mental illness? Though the quality and strength of the literature is at best patchy, the general conclusion is that there is an association between higher levels of some types of social capital and a lower risk of mental health problems. This chapter discusses the possible mechanisms at multiple levels through which social capital may change the risk and rates of mental illness.

Chemical Vapor Deposition (CVD) tungsten metallization is used to increase VLSI device performance due to its low resistivity, and improved reliability over other metallization schemes. Because of its conformal nature as a blanket film, CVD-W has been adapted to multiple levels of metal which increases circuit density. It has been used to fabricate 16 MBIT DRAM technology in a manufacturing environment, and is the metallization for 64 MBIT DRAM technology currently under development. In this work, we investigate some sources of contamination. One possible source of contamination is impurities in the feed tungsten hexafluoride (WF6) gas. Another is particle generation from the various reactor components. Another generation source is homogeneous particle generation of particles from the WF6 gas itself. The purpose of this work is to investigate and analyze CVD-W process-generated particles, and establish a particle characterization methodology.
