Semiconductor process design

Even listing all above problems and requirements leading to their solution indicates that development of the method of semiconductor chemical sensors opens a wide research domain. In order to resolve this problems and implement all capabilities of the method of semiconductor sensors there are two ways now the old trial and error approach and approach related to further studies of physical and chemical properties of surface phenomena, reactions and processes underlying this method. It is quite clear that the second approach is more promising in order to obtain semiconductor sensors designed for the use in accurate scientific studies and for practical gas analysis. 

Both organic and Inorganic species can be Identified from SIMS mass spectra (12). One specialized commercial SIMS Instrument was designed to determine the molecular weight and structure of nonvolatile organic compounds (5fl). Although molecular SIMS has not been widely exploited for semiconductor process... 

The FMEA methodology is now extensively used in a variety of industries including semiconductor processing, food service, plastics, software and health care, where it is sometimes integrated into Advanced Product Quality Planning (APQP) to provide a primary design and process risk mitigation tool. 

These fluid handling components are nearly always solid fluoropolymer constructions. These designs are possible because sizes are relatively small compared with functionally similar but far larger components used in the CPI. Therefore, mechanical properties and material cost are not particularly sensitive issues. In addition, semiconductor processes are easily compromised by the presence of tiny amounts of metallic ions, so manufacturers avoid having metal components in the vicinity of process fluids. 

Within the following sections we will discuss fundamental aspects of nanoparticle processing including the most important steps of characterization, particle formation, stabilization and post processing to end up with some general conclusions for a future process design. As model materials we use technically relevant semiconductor nanoparticles, so-called quantum dots (QDs) with direct band gap (ZnO, manganese doped ZnS and PbS(e)) and silver nanowires which have been proven to be excellent transparent electrodes for thin film solar cells [27].
