ABSTRACT
This chapter focuses on the current trends in atomistic simulation methodology, adopted by several industry leaders for future technology nodes and revolutionary devices. Electronic design automation (EDA) has been the key enabler of the fabless semiconductor industry. The final era of full-service EDA companies belongs to a strategy called grow by accumulating fundamental startup companies. Moreover, companies now focus on design-technology-co-optimization and advance R&D on atomic-level simulation. The one-electron system is the simplest bound system that occurs in nature and it is the simplest case to study atomic behavior quantum mechanically. Two and more atoms can combine to form a stable molecule and the details of interatomic forces necessary to bind atoms into the molecule, the nature of energy level, and spectra of the molecule are important before one understands molecular level statistics. A molecule is a stable arrangement of a group of nuclei and electrons.
