[paper] RESURF Model and Electrical Characteristics of Finger-Type STI Drain Extended MOS Transistors

RESURF Model and Electrical Characteristics of Finger-Type STI Drain Extended MOS Transistors
H. C. Tsai, R. H. Liou and C. Lien
IEEE Transactions on Electron Devices
vol. 63, no. 12, pp. 4603-4609, Dec. 2016

Abstract: Finger-type shallow trench isolation (finger STI) drain extended MOS transistors are fabricated and its electrical characteristics is studied. Polyplate on a finger STI served as a reduced surface field is adopted to enhance breakdown voltage (BV) by reducing the effective doping concentration of the drain extension (DE) finger. The conformal mapping method, which relates the reduction of the doping concentration to the width (zo) of the DE finger, the gap (zd) between the polyplate and the DE finger, and the STI depth (ys), is used to estimate the reduction of the doping concentration theoretically. Based on this reduced doping concentration, a BV model is derived. The predictions of this model agree very well with the experimental data.

[paper] Analysis of aging effects - From transistor to system level

Analysis of aging effects - From transistor to system level
Maike Taddiken*, Nico Hellwege, Nils Heidmann, Dagmar Peters-Drolshagen, Steffen Paul
Institute of Electrodynamics and Microelectronics,
University of Bremen, Otto-Hahn-Allee 1, Bremen 28359,Germany

ABSTRACT: Due to shrinking feature sizes in integrated circuits, additional reliability effects have to be considered which influence the functionality of the system. These effects can either result from the manufacturing process or external influences during the lifetime such as radiation and temperature. Additionally, modern technology nodes are affected by time-dependent degradation i.e. aging. Due to the age-dependent degradation of a circuit, processes on the atomic scale of the semiconductor material lead to charges in the oxide silicon interface of CMOS devices, altering the performance parameters of the device and subsequently the behavior of the circuit. With the continuous downscaling of modern semiconductor technologies, the impact of these atomic scale processes affecting the overall system characteristics becomes more and more critical. Therefore, aging effects need to be assessed during the design phase and actions have to be taken guaranteeing the correct system functionality throughout a system’s lifetime. This work presents methods to investigate the influence of age-dependent degradation as well as process variability on different levels. An operating-point dependent sizing methodology based on the gm/ID method extended to incorporate aging, which aims at developing aging-resistent circuits is presented. The basic idea of the gm/ID sizing method is the dependence of the operating point of a MOS transistor on the state of inversion in the channel, its strong relation to circuit performance and the possibility to calculate transistor dimensions.The inversion coefficient IC is a fundamental metric within the gm/ID method and numerically represents the inversion level of a MOS device formally described in the EKV MOS model. Additionally, the sensitivity of circuit performances in regard to aging can be determined. In order to investigate the reliability of a complex system on behavioral level, a modeling method to represent the performance of system components in dependence of aging and process variability is introduced.

[paper] Field programmable analog array: A boon for analog world

Field programmable analog array: A boon for analog world
Dipti and B. V. R. Reddy,
2016 3rd International Conference on Computing for Sustainable Global Development 
(INDIACom), New Delhi, India, 2016, pp. 2975-2980.

Abstract: n analog chips designing, fabricating, and testing takes a lot of time, money and perfection. In contrast design of digital integrated circuits is fully automated now a day. Due to simpler nature of digital circuits, as compared to Analog circuits, leads to development of libraries and synthesis tools for fast synthesis of digital circuits. To reduce the cost and time-to-market CPLDs and FPGAs are generally used for prototyping of digital integrated circuits. But FPAAs i.e Field Programmable Analog Arrays are boon for designing of analog and mixed-signal Integrated Circuits because of rapid prototyping. FPAA is not only optimal for all solution in contrast to FPGAs but it also reduces the verification and designing cost. This again results from complex nature of analog circuits which needs factors like signal to noise ratio, bandwidth, frequency response, linearity etc. to be addressed. FPAAs are made using configurable analog blocks (CAB) and networks, which are used to provide required interconnection among Cabs. Like FPGAs, circuit functionality is much more sensitive to parasitics introduced by the programming devices in FPAA. So the design of FPAAs architecture and CABs are mutually dependent. To design an efficient FPAA, a designer needs to compromise between flexibility and the number of programmable switches in designing FPAA architectures and the CAB topologies. Various papers are studied for different topologies used in FPAAs and various applications designed with the use of FPAA. In March 2013, Paul Hasler come up with automated approach based on EKV model for characterization of device mismatch, second order defects with temperature. After verification of characterization current sources were created with 2.2% RMS error over dynamic range of 25dB. Field programmable gate array represents a new direction to analog and mixed signal domain keeping the idea of FPGAs in digital domain. RASP is useful for analog designers because they can save the analog components in the form of CABs. RASPER tool was developed for placement and routing of RASP 2.7 and RASP 2.8 versions Whereas GRASPER was developed for RASP 2.9.In digital circuits parasitic only affect the speed of operation but in analog circuits they plays a crucial role for circuit performance and functionality. Floating gate technology was used to simplify designing and implementation, increased system reliability, high precision, innovative approach. In near future FPAA technology will come up with better architecture, low power and more applications with less time to market.
