A Radiation Hardened Linear Macrocell Array

Abstract

This paper describes the development and combination of monolithic radiation hardened linear macrocells.These are used as replacements for hybridized bipolar SSI (Small Scale Integration) linear microcircuits, discrete semiconductors and passive devices, at low technical, schedule and cost risk. The silicon technology used in the fabrication of such circuits is conventional; however, the approach develops achievable next generation design and fabrication techniques for producing radiation hardened linear microcircuits at reduced cost with high reliability. The paper discusses the selected technology, process, design approach, testability and testing implications, improvements in yield and reliability and the post radiation performance obtained by the semicustom macrocell approach at the device and cell level.
