Semiconductor devices : modelling and technology
You have seen how, we have started with the first metal gate MOSFET technology and then, you have switched over to the polysilicon gate technology, because it gives a self-aligned technique. Particularly, as the device dimensions become smaller, the problem of the overhang capacitance or the overlap capacitance between the gate and the source and the drain becomes more and more severe and therefore, you would prefer to have a self-aligned technique, right and for that you have been using polysilicon gate MOSFET and then, we have also told you that you use a thick field oxide; the field oxide thickness must be large, so that the parasitic MOSFET has a very high threshold voltage, but at the same time if the field oxide thickness is very large it creates a problem of surface topography, right. That is the surface has a lot of ups and downs. So, in order to prevent it and have a planar surface, what do you use? That is you protect the active transistor region with a nitride oxide mask and then you have a local oxidation carried out in the rest of the region; you can either have this local oxide fully recessed or partially recessed.
You now have a source you can cite with authority, confidence, and credibility. Edited by a distinguished authority in the field and containing contributions from a variety of experts, the book discusses preanalytical variables, the pitfalls of immunoassays, tandem mass spectrometry, issues related to pain management and herbal supplements, and therapeutic drug monitoring for a range of medications, including:. Examing older and newer drugs, the book contains detailed discussions on the rationale for therapeutic drug monitoring of each class of drugs, along with their basic pharmacology and toxicology. An extensive list of references is provided at the end of each chapter so that those interested in implementing a new drug assay can find the most appropriate method for the intended drug. This classic book has set the standard for advanced study and reference in the semiconductor device field. Now completely updated and reorganized to reflect the tremendous advances in device concepts and performance, this Third Edition remains the most detailed and exhaustive single source of information on the most important semiconductor devices.
