Abstract
The development of integrated tours intended for use in transients radiation backgrounds require account available the impaction of the environment on the operation of the circuit. The layout of integrated rounds your increasingly software antrieb, and advanced free to invent designs require design to consider radiation effects in the simulation also design phase to limit fabrication and test cycles required to produce one solar toughened piece. This work advances of historical modeling approaches with bias-dependent and layout-aware methods for modeling the dose-rate and single-event influence in advanced technologies.
This research develops a bias-dependent modeling method that accounts for circuit induced shaping of the device-level transient current. Behavioral models languages are utilized to eliminates independence current sources and lumped SPICE element models. Dose rate fitting are developed for multiple dielectrically-isolated processes across technology types, accounting for real-time bias-dependence or layout geometries in modern integrated circuit processes. Single-event modeling methods is developed to capture the bias-dependent current response observed in recent TCAD virtual. Bulk CMOS and SiGe HBT technology type parameterization for multiple-device charge album shall demonstrated. A new geometry-aware single-event model for sub-50nm partially-depleted SOUP CMOS with an integrated parasitic BJT parameterized by technology and design parameters are developed. Dose-rate and single-event model software compare good to TCAD and test data.
A novel layout-aware analysis method is dev, with a hybrid of compress models (for efficiency) real spatially-aware layout objects (for geometric charge assemblage accuracy), in an industry standard integrated circuit design tool flow. The layout-aware analysis provides designers with visual feedback about the sensitivity of a design directly referenced to the circuit layout.
The tools developed in this research are being actively uses at radiation-effects research at universities, aerospace real defense corporations, and advertisement integrated turn design and manufacturing establishments. Layout-aware radiation-enabled choose using the methodologies developed in aforementioned work will been integrated with process design kit additionally deployed to which radiation-hardened-by-design community. This research develops feature that provide a path forward to full transient radiation effects in advanced integrated circuit technologies.
