Available in PDF, EPUB and Kindle. Book excerpt: The aim of BiCMOS technology is to combine two different process technologies intoa single chip, reducing the number of external components and optimizing power consumptionfor RF, analog and digital parts in one single package. Given the respectivestrengths of HBT and CMOS devices, especially high speed applications benefit fromadvanced BiCMOS processes, that integrate two different technologies.For analog mixed-signal RF and microwave circuitry, the push towards lower powerand higher speed imposes requirements and presents challenges not faced by digitalcircuit designs. Accurate compact device models, predicting device behaviour undera variety of bias as well as ambient temperatures, are crucial for the development oflarge scale circuits and create advanced designs with first-pass success.As technology advances, these models have to cover an increasing number of physicaleffects and model equations have to be continuously re-evaluated and adapted. Likewiseprocess scaling has to be verified and reflected by scaling laws, which are closelyrelated to device physics.This thesis examines the suitability of the model formulation for applicability to production-ready SiGe HBT processes. A derivation of the most recent model formulationimplemented in HICUM version L2.3x, is followed by simulation studies, whichconfirm their agreement with electrical characteristics of high-speed devices. Thefundamental geometry scaling laws, as implemented in the custom-developed modellibrary, are described in detail with a strong link to the specific device architecture.In order to correctly determine the respective model parameters, newly developed andexisting extraction routines have been exercised with recent HBT technology generationsand benchmarked by means of numerical device simulation, where applicable.Especially the extraction of extrinsic elements such as series resistances and parasiticcapacitances were improved along with the substrate network.The extraction steps and methods required to obtain a fully scalable model library wereexercised and presented using measured data from a recent industry-leading 55nmSiGe BiCMOS process, reaching switching speeds in excess of 300GHz. Finally theextracted model card was verified for the respective technology.

Available in PDF, EPUB and Kindle. Book excerpt: A new SPICE-type, HBT large-signal model is described with special emphasis on the associated parameter extraction techniques. The model can be used to simulate HBT's under DC, microwave small-signal and large-signal conditions. Also, allowance is made for self-heating effects, which are quite pronounced in HBT's.

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 2017-07-26 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The trend in modern electronics towards ever higher frequencies of operation and complexity as well as power efficiency requires a whole palette of different technologies to be available to circuit designers for various applications. While MOSFETs dominate the digital world, they have apparently reached their top analogue performance around the 65nm node. Emerging technologies such as CNTFETs offer excellent properties such as very high linearity and speed in theory, but have yet to deliver on those promises in practice. Heterojunction bipolar transistors (HBTs), on the other hand, offer a number of key advantages over competing technologies: A very high transconductance and therefore a relatively low impact of a load impedance on the transistor operation, a high transit frequency and maximum frequency of oscillation at a comparatively relaxed feature size and favorable noise characteristics. Like all semiconductor devices, HBTs can be fabricated in diferent semiconductor materials. The most common are SiGe HBTs, which even today reach values above (ft; fmax) = (300; 500) GHz and are projected to eventually reach the THz range. However, HBTs fabricated in III-V materials offer a versatile alternative. Depending on the materials that are used, III-V HBTs can be the fastest available bipolar transistors (competing only with HEMTs, also fabricated in III-V materials, for the title of fastest available transistors overall), offer very high breakdown voltages and therefore excellent power-handling capability, show good linearity or low noise figures at high frequencies. Typical applications for III-V HBTs include handset PAs, high-effciency and high-speed amplifiers as well as high-speed oscillators . Overall, III-V-based HBTs and especially InP HBTs are excellent candidates for future high-speed communication circuits. The goal of this work is to include important effects occurring in III-V materials in a compact model for circuit design in a physical, yet intuitiv

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.
