This book was released on 2015-10-14 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon-Germanium Heterojunction Bipolar Transistors (SiGe HBTs) are perfectly suited for high-speed electronics. Since the fabrication costs per design cycle are rapidly increasing with progressing frequency and complexity of the systems, accurate compact models are essential in order to enable robust circuit design. This thesis focuses on selected important physical effects in advanced SiGe HBTs, which have been either insufficiently modeled or completely missing in conventional compact models. New compact model equations for the transfer current were derived and successfully applied to a large set of different technologies. Hereby, the "Generalized Integral Charge Control Relation" was used as a foundation. A physics-based model utilizing small-signal parameters obtained from measurements is derived for modeling the current dependent collector charge. A brief chapter about substrate effects in bipolar transistors comprises the derivation of a compact model for the bias-dependent substrate resistance as well as a proper partitioning of the substrate capacitance. New extraction methods for compact model parameters are introduced and the application of existing methods to advanced processes is discussed. The derived joint extraction method for the emitter and thermal resistance as well as a scalable model for the transfer current have been successfully applied to experimental data of fast HBTs. The derived model equations were applied to a selected very advanced SiGe HBT process developed by IHP. Highly accurate models for DC- and small-signal as well as for large-signal characteristics are presented.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bipolar complementary metal-oxide-semiconductor (BiCMOS) processescan be considered as the most general solution for RF products, as theycombine the mature manufacturing tools of CMOS with the speed and drivecapabilities of silicon-germanium (SiGe) heterojunction bipolar transistors(HBTs). HBTs in turn are major contenders for partially filling the terahertzgap, which describes the range in which the frequencies generated bytransistors and lasers do not overlap (approximately 0.3THz to 30 THz). Toevaluate the capabilities of such future devices, a reliable prediction methodologyis desirable. Using a heterogeneous set of simulation tools and approachesallows to achieve this goal successively and is beneficial for troubleshooting.Various scientific fields are combined, such as technology computer-aided design(TCAD), compact modeling and parameter extraction.To create a foundation for the simulation environment and to ensure reproducibility,the used material models of the hydrodynamic and drift-diffusionapproaches are introduced in the beginning of this thesis. The physical modelsare mainly based on literature data of Monte Carlo (MC) or deterministicsimulations of the Boltzmann transport equation (BTE). However, the TCADdeck must be calibrated on measurement data too for a reliable performanceprediction of HBTs. The corresponding calibration approach is based onmeasurements of an advanced SiGe HBT technology for which a technology specific parameter set of the HICUM/L2 compact model is extracted for thehigh-speed, medium-voltage and high-voltage transistor versions. With thehelp of the results, one-dimensional transistor characteristics are generatedthat serve as reference for the doping profile and model calibration. By performingelaborate comparisons between measurement-based reference dataand simulations, the thesis advances the state-of-the-art of TCAD-based predictionsand proofs the feasibility of the approach.Finally, the performance of a future technology in 28nm is predicted byapplying the heterogeneous methodology. On the basis of the TCAD results,bottlenecks of the technology are identified.

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.

Download or read book Noise Modelling of Silicon Germanium Heterojunction Bipolar Transistors at Millimetre wave Frequencies written by Kenneth Hoi Kan Yau and published by . This book was released on 2006 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using 2D device simulations, it is predicted that the cutoff frequencies of SiGe HBTs can be scaled beyond 500GHz. These devices have the potential to enable advanced millimetre-wave circuits. However, shot noise correlation, which is captured through noise transit time, becomes increasingly important as circuit designers continue to push the operating frequencies of the circuits. The technique for extracting the SiGe HBT noise parameters only from the measured y-parameters is extended to account for the presence of correlation. Unlike earlier publications, this method does not need to fit the noise transit time to measured noise data. The technique was validated using 2D device simulations and measured noise parameter data. It was found that the NFMIN of SiGe HBTs with & fnof; T/ & fnof;MAX of 160GHz is approximately 1.5dB lower at 60GHz when noise correlation is accounted for. However, for these devices, noise correlation proves to be insignificant below 18GHz.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work investigates the technology development of state-of-the-art SiGe and SiGeC Heterojunction Bipolar Transistors (HBT) by means of technology computer aided design (TCAD). The objective of this work is to obtain an advanced HBT very close to the real device not only in its process fabrication steps, but also in its physical behavior, geometric architecture, and electrical results. This investigation may lead to achieve the best electrical performances for the devices studied, in particular a maximum operating frequency of 500 GHz. The results of this work should help to obtain more physical and realistic simulations, a better understanding of charge transport, and to facilitate the development and optimization of SiGe and SiGeC HBT devices.The TCAD simulation kits for SiGe/SiGeC HBTs developed during our work have been carried out in the framework of the STMicroelectronics bipolar technology evolution. In order to achieve accurate simulations we have used, developed, calibrated and implemented adequate process models, physical models and extraction methodologies. To our knowledge, this work is the first approach developed for SiGe/SiGeC HBTs which takes into account the impact of the strain, and of the germanium and carbon content in the base, for both: process and electrical simulations.In this work we will work with the successive evolutions of B3T, B4T and B5T technologies. For each new device fMAX improves of 100 GHz, thus the technology B3T matches to 300 GHz, B4T and B5T to 400 and 500 GHz, respectively.Chapter one introduces the SiGe SiGeC heterojunction bipolar technologies and their operating principles. This chapter deals also with the high frequency AC transistor operation, the extraction methods for fMAX and the carrier transport in extremely scaled HBTs.Chapter two analyzes the physical models adapted to SiGeC strained alloys used in this work and the electrical simulation of HBT devices. This is also an important work of synthesis leading to the selection, implementation and development of dedicated models for SiGeC HBT simulation.Chapter three describes the B3T TCAD simulation platform developed to obtain an advanced HBT very close to the real device. In this chapter the process fabrication of the B3T technology is described together with the methodology developed to simulate advanced HBT SiGeC devices by means of realistic TCAD simulations.Chapter four describes the HBT architectures developed during this work. We will propose low-cost structures with less demanding performance requirements and highly performing structures but with a higher cost of production. The B4T architecture which has been manufactured in clean-room is deeply studied in this chapter. The impact of the main fabrication steps is analyzed in order to find the keys process parameters to increase fMAX without degrading other important electrical characteristics. At the end of this chapter the results obtained is used to elaborate a TCAD simulation platform taking into account the best trade-off of the different key process parameters to obtain a SiGeC HBT working at 500 GHz of fMAX.
