Available in PDF, EPUB and Kindle. Book excerpt: Complemetary metal-oxide-semiconductor (CMOS) is currently the most dominant technology used in making integrated systems. It consists of both n-channel MOS transistor (NMOS) and p-channel MOS transistor (PMOS) fabricated on the same substrate. Conventionally, the substrate is made of silicon. Alternatively, the substrate can be made from different layer of semiconductors known as heterostructure. Much attention has been given to Si/SiGe due to its compatibility with silicon and the higher carrier mobilities. SiGe is an alloy which is said to be an alternative solution to the problem of a down-scaled CMOS to produce high speed device. This work consists of modeling three different of Si/SiGe heterostructure substrates which are used to construct n- and p-channel MOSFETs and later to construct CMOS inverter. The three types of heterostructures are a strained SiGe on silicon substrate, a strained silicon on relaxed SiGe/Si substrate and a strained SiGe on strained Si/relaxed layers of SiGe/Si substrate. A device simulator, Avanti MEDICI Version 1999.2 is used in this project. Although it has heterojunction capability, it does not support model for a strained Si. This work also highlights the method to simulate Si/SiGe heterostructures containing strained layer using MEDICI. Simulations on the band structure and current-voltage (I-V) characteristics of the MOSFETs are carried out. The Id-Vg and Id-Vd are simulated for different value of Ge% and mobility. This is to observe the effect of varying the value of Ge% and mobility used in the design. The simulation on the CMOS inverter as the fundamental circuit is carried out to obtain the transfer curve. The noise margin and switching characteristics can be extracted from the transfer curve. All the simulated results are then compared with the Si bulk, the analyses show that the performance of the Si/SiGe heterostructures is better in terms of the electrical characteristics of the MOSFETs and the switching characteristics of the CMOS inverter, as compared to the performance of the Si bulk.

This book was released on 2018-10-03 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: When you see a nicely presented set of data, the natural response is: “How did they do that; what tricks did they use; and how can I do that for myself?” Alas, usually, you must simply keep wondering, since such tricks-of- the-trade are usually held close to the vest and rarely divulged. Shamefully ignored in the technical literature, measurement and modeling of high-speed semiconductor devices is a fine art. Robust measuring and modeling at the levels of performance found in modern SiGe devices requires extreme dexterity in the laboratory to obtain reliable data, and then a valid model to fit that data. Drawn from the comprehensive and well-reviewed Silicon Heterostructure Handbook, this volume focuses on measurement and modeling of high-speed silicon heterostructure devices. The chapter authors provide experience-based tricks-of-the-trade and the subtle nuances of measuring and modeling advanced devices, making this an important reference for the semiconductor industry. It includes easy-to-reference appendices covering topics such as the properties of silicon and germanium, the generalized Moll-Ross relations, the integral charge-control model, and sample SiGe HBT compact model parameters.

Available in PDF, EPUB and Kindle. Book excerpt: SiGe HBTs are the most mature of the Si heterostructure devices and not surprisingly the most completely researched and discussed in the technical literature. However, new effects and nuances of device operation are uncovered year-after-year as transistor scaling advances and application targets march steadily upward in frequency and sophistication. Providing a comprehensive treatment of SiGe HBTs, Silicon Heterostructure Devices covers an amazingly diverse set of topics, ranging from basic transistor physics to noise, radiation effects, reliability, and TCAD simulation. Drawn from the comprehensive and well-reviewed Silicon Heterostructure Handbook, this text explores SiGe heterojunction bipolar transistors (HBTs), heterostructure FETs, various other heterostructure devices, as well as optoelectronic components. The book provides an overview, characteristics, and derivative applications for each device covered. It discusses device physics, broadband noise, performance limits, reliability, engineered substrates, and self-assembling nanostructures. Coverage of optoelectronic devices includes Si/SiGe LEDs, near-infrared detectors, photonic transistors for integrated optoelectronics, and quantum cascade emitters. In addition to this substantial collection of material, the book concludes with a look at the ultimate limits of SiGe HBTs scaling. It contains easy-to-reference appendices on topics including the properties of silicon and germanium, the generalized Moll-Ross relations, and the integral charge-control model, and sample SiGe HBT compact model parameters.

Download or read book Technology for SiGe Heterostructure based CMOS Devices written by Mark Albert Armstrong and published by . This book was released on 1999 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bulk silicon is currently the substrate material of choice for the manufacture of high performance digital circuits due to its highly-developed processing technology and the relatively low cost for high-quality substrates. Silicon-based MOSFETs have reached remarkable levels of performance through device scaling. However, with each technology generation, it is becoming harder and harder to improve device performance at the same pace through traditional scaling methods alone. Short-channel effects such as velocity saturation and drain-induced barrier lowering have placed an fundamental limit on the ultimate performance of bulk Si MOSFETS. One way to raise this limit is to increase the carrier mobilities in the channel. This can be done using high-mobility Si and SiGe strained-layers. Unlike III-V-based high-mobility materials, Si/SiGe strained-layers have the advantage of being largely compatible with mainstream Si processing, which is important from a financial feasibility standpoint. This thesis examines several issues related to Si/SiGe strained-layer devices and their integration into mainstream CMOS. The first part of this work strives to predict the performance leverage of high-mobility Si/ SiGe over bulk Si devices and circuits in a realistic manner. Two-dimensional hydrodynamic simulations are used to predict static device characteristics including effects of series resistance, velocity saturation and velocity overshoot. The simulations show enhanced current drive over bulk Si devices at 0.2 [mu]m effective channel length and highlight the importance of velocity overshoot in high-mobility submicron devices. The circuit performance of Si/SiGe devices is determined from transient simulations of CMOS ring oscillators including the effects of parasitic capacitance and drain-to-source voltage at the onset of saturation Vds.sat. The simulations show a 4 to 6-fold reduction in power-delay product as compared to bulk CMOS oscillators operated at 2.5 V with the same design rules. The remainder of the thesis focuses on the fabrication and characterization of strained-Si NMOS devices. The vehicle for this work is a novel short-flow, single-mask MOSFET which can be fabbed in as little as a week. This device is superior to simple Hall mobility structures which suffer from leakage through the substrate, an inability to control the. carrier concentration and the uncertainty associated with the Hall scattering factor. I investigate a novel buried-channel strained-Si NMOS structure incorporating an n-type donor layer beneath the strained-Si channel to encourage occupation of the buried channel and increase the overall mobility. Peak mobility in a structure without a donor layer reproduces the best results in the literature for buried-channel strained-Si NMOS devices. For structures with donor layers, Coulomb scattering from charges in the donor layer eradicates any benefit from increased buried-channel occupation. I also investigate the effect of well implants on the mobility of surface . channel strained-Si NMOS devices. Similar to the universal mobility curve in bulk Si, mobility at low perpendicular electric field degrades with increasing implant dose while high field mobility is unaffected. The mobility is largely unaffected by a neutral implant species at the same dose. This leads to the conclusion that the material quality of the strained-layer is not affected by the implant, and that the mobility degradation is due solely to increased ionized impurity scattering.
