Russian Instrument Engineering on the Issue Development of Electronic Components and Application of Compact SPICE Models

At present, in the conditions of technological limitations, the most important task is the rapid restoration and modernization of the Russian microelectronics industry. And this is problematic without the appearance in the country of modern crystal rulers with design standards less than 0.25 microns. The creation of crystal technology is a very expensive and knowledge-intensive process, which includes not only the acquisition and launch of the entire fleet of technological equipment, but also the development of the necessary routing technologies, which involve the creation of a PDK (process design kit), allowing developers of ultra-large-scale integrated circuits, using computer-aided design systems, to design a crystal that, in terms of electrical parameters and characteristics with an acceptable error, will completely coincide with the test results of the manufactured crystal. This is achieved through the use of Simulation Program with Integrated Circuit Emphasis - SPICE models, which allow you to accurately and reliably describe the operation of the active elements of the circuit, primarily transistors. To assess the current state and determine the route for creating complete SPICE models for a specifically selected technology, the article analyzes technical information on this issue: basic concepts, structure, types, selection criteria and scope of application of SPICE models. Based on the results of the analysis, a route for creating complete SPICE models of transistors was outlined.

I. Introduction

Modern electronics development involves the creation of basic electrical circuits consisting of various electronic components (resistors, capacitors, inductors, diodes, transistors, etc.). The operation of all these electronic components is based on physical laws, physical effects or phenomena that have their own description (behavioral model) in the form of mathematical equations, circuit diagrams or tables. The main property of these models is to reliably and most accurately describe the behavior of a real device relative to its terminals in different operating modes. The accuracy of the description of mathematical models of components determines how reliably the results of modeling a circuit diagram will coincide with the operation of a physical prototype assembled from real electronic components.
