Abstract
Vacuum insulated glass units having layered pillars. The glass units include two glass panes and an edge seal between the glass panes with a substantial vacuum gap between them. A plurality of pillars are located between the glass panes as spacers to maintain the vacuum gap. The pillars have a sintered ceramic, alpha alumina, or zirconia body with a tapered sidewall and a functional layer on a surface of the body.
