There have been some claims made recently that planar Fully Depleted Silicon On Insulator (FDSOI) is less expensive than bulk planar processes and FinFETs at various nodes. Some of these claims suggest that FinFETs in particular are significantly more expensive. My company, IC Knowledge LLC produces the most widely used IC cost modeling software in the semiconductor industry. Recently we have developed a new version of our Strategic Cost Model that is particularly well suited for cost comparison between bulk, FDSOI (planar) and FinFETs (both on bulk and SOI). In the rest of this article I will presents some results from these comparisons.
