To address the increasing demands of device scaling, new materials are being introduced into conventional Si CMOS processing at an unprecedented rate. Presentations collected here focus on understanding, from a chemistry and materials perspective, the mechanism of interface formation and defects at interfaces, for both conventional Si and alternative channel (Ge or III-V) systems. Several papers address reliability concerns for high-k/metal gate (basic physical models, charge trapping, etc.), while others cover characterization of the thin films and interfaces which comprise the gate stack. Topics include: advanced Si-based gate stacks; and alternate channel materials.

Materials Fundamentals of Dielectric Gates treats materials fundamentals of the novel gate dielectrics that are being introduced into semiconductor manufacturing to ensure the continuous scaling of the CMOS devices. This is a very fast evolving field of research so the focus is materials, mostly transition metal oxide, that determine performance in device applications. The complexity of the structure-property relations in TM oxides makes the use of the state-of-the-art first-principles calculations necessary. Several chapters give a detailed description of the modern theory of polarization, and heterojunction band discontinuity within the framework of the density functional theory. Experimental methods include oxide melt solution calorimetry and differential scanning calorimetry, Raman scattering and other optical characterization techniques, transmission electron microscopy, and x-rayphotoelectron spectroscopy. Since many of the problems encountered in the world of CMOS are also relevant for other semiconductors such as GaAs, a comprehensive review of recent developments in this field is thus also given

This book describes the basic physical principles of the oxide/semiconductor epitaxy and offers a view of the current state of the field. It shows how this technology enables large-scale integration of oxide electronic and photonic devices and describes possible hybrid semiconductor/oxide systems. The book incorporates both theoretical and experimental advances to explore the heteroepitaxy of tuned functional oxides and semiconductors to identify material, device and characterization challenges and to present the incredible potential in the realization of multifunctional devices and monolithic integration of materials and devices. Intended for a multidisciplined audience, Integration of Functional Oxides with Semiconductors describes processing techniques that enable atomic-level control of stoichiometry and structure and reviews characterization techniques for films, interfaces and device performance parameters. Fundamental challenges involved in joining covalent and ionic systems, chemical interactions at interfaces, multi-element materials that are sensitive to atomic-level compositional and structural changes are discussed in the context of the latest literature. Magnetic, ferroelectric and piezoelectric materials and the coupling between them will also be discussed. GaN, SiC, Si, GaAs and Ge semiconductors are covered within the context of optimizing next-generation device performance for monolithic device processing.
