Available in PDF, EPUB and Kindle. Book excerpt: Ferroelectric perovskite thin films for voltage tunable applications, namely (Ba, Sr)TiO3 (Barium Strontium Titanate or BST) and (Pb, Sr)TiO3 (Lead Strontium Titanate or PST), are synthesized via the so-called sol-gel route. While BST shows the tendency to severe film cracking, PST can be grown crack free onto platinised Si standard substrates and even directly onto SiO2, SiNx or bare Si. The growth kinetics of PST on platinised SiO2/Si and directly on SiO2/Si are studied in detail using X-ray diffractometry (XRD), scanning electron and atomic force microscopy, SEM and AFM respectively. It is shown that PST begins to crystallise at 500°C on Ti/Pt and 550°C directly on SiO2. After a thermal treatment of 650°C for 15 min both films are fully crystallised with random (100) and (110) orientation and a smooth surface. The dielectric properties, e.g. dielectric constant, loss and tunability, of PST 50/50 are measured using a standard Ti/Pt bottom electrode with Cr/Au top electrodes and a TiW/Cu bottom electrode on which the PST thin film was bonded with TiW/Cu top electrodes. The Cu/PST/Cu system shows an enhanced performance in terms of loss resulting in a larger device quality factor and a figure of merit (FOM) of 18.25 compared to 16.6 for the configuration using a Pt bottom electrode. The maximum tunability is 73% with an applied voltage of 35V and the dielectric constant at zero bias is ~ 420 with a loss

Download or read book Ferroelectric Thin Films written by Carlos Paz de Araujo and published by Taylor & Francis US. This book was released on 1996 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for the rapid development of thin film technology, relative to that of bulk materials, is its application to a variety of microelectronic products. Many of the characteristics of thin film ferroelectric materials are utilized in the development of these products - namely, their nonvolatile memory and piezoelectric, pyroelectric, and electro-optic properties. It is befitting, therefore, that the first of a set of three complementary books with the general title Integrated Ferroelectric Devices and Technologies focuses on the synthesis of thin film ferroelectric materials and their basic properties. Because it is a basic introduction to the chemistry, materials science, processing, and physics of the materials from which integrated ferroelectrics are made, newcomers to this field as well as veterans will find this book self-contained and invaluable in acquiring the diverse elements requisite to success in their work in this area. It is directed at electronic engineers and physicists as well as process and system engineers, ceramicists, and chemists involved in the research, design, development, manufacturing, and utilization of thin film ferroelectric materials.

Available in PDF, EPUB and Kindle. Book excerpt: Ferroelectric materials have been and still are widely used in many applications, that have moved from sonar towards breakthrough technologies such as memories or optical devices. This book is a part of a four volume collection (covering material aspects, physical effects, characterization and modeling, and applications) and focuses on ways to obtain high-quality materials exhibiting large ferroelectric activity. The book covers the aspect of material synthesis and growth, doping and composites, lead-free devices, and thin film synthesis. The aim of this book is to provide an up-to-date review of recent scientific findings and recent advances in the field of ferroelectric materials, allowing a deep understanding of the material aspects of ferroelectricity.

Available in PDF, EPUB and Kindle. Book excerpt: Ferroelectric thin films have been integrated with silicon micromechanical structures in the fabrication of microsensor and microactuator structures. Both the piezoelectric and pyroelectric effects in thin films of lead zirconate titanate (Pb(ZrxTil-x)03) and lead titanate (PbTiO3) have been used for physical force sensing (pressure sensor), thermal heat sensing (pyroelectric infrared detector), and microactuation (mechanical positioner). Solid-state micromachining is used to form mechanical membranes on a silicon wafer for implementing easily deformable membranes of structures with a low thermal mass. This paper demonstrates the compatible simultaneous integration of 1) sol-gel deposited ferroelectric thin films, 2) surface-machined micromechanical structures, and 3) n-well CMOS integrated circuit technologies.

This book was released on 2013-11-27 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past five years have witnessed some dramatic developments in the general area of ferroelectric thin films materials and devices. Ferroelectrics are not new materials by any stretch ofimagination. Indeed, they have been known since the early partofthis century and popular ferroelectric materials such as Barium Titanate have been in use since the second world war. In the late sixties and seventies, a considerable amountofresearch and development effort was made to create a solid state nonvolatile memory using ferroelectrics in a vary simple matrix-addressed scheme. These attempts failed primarily due to problems associated with either the materials ordue to device architectures. The early eighties saw the advent of new materials processing approaches, such as sol-gel processing, that enabled researchers to fabricate sub-micron thin films of ferroelectric materials on a silicon substrate. These pioneering developments signaled the onsetofa revival in the areaofferroelectric thin films, especially ferroelectric nonvolatile memories. Research and development effort in ferroelectric materials and devices has now hit a feverish pitch, Many university laboratories, national laboratories and advanced R&D laboratories oflarge IC manufacturers are deeply involved in the pursuit of ferroelectric device technologies. Many companies worldwide are investing considerable manpower and resources into ferroelectric technologies. Some have already announced products ranging from embedded memories in micro controllers, low density stand-alone memories, microwave circuit elements, andrf identification tags. There is now considerable optimism that ferroelectric devices andproducts will occupy a significant market-share in the new millennium.
