Sounds about right. Maybe a little too generous on the lower row.

"John Rogers, working with colleagues at the University of Illinois at Urbana-Champaign and a related company, offer a production method by adapting a transfer-printing technique that they have been developing for the past few years. They begin by growing stacks consisting of multiple layers of gallium arsenide and aluminium gallium arsenide, which they then "peel" off one-by-one using a silicone-based stamp. The layers detach easily on account of van der Waals forces, which are stronger on the stamp surface than between layers of compound semiconductor. The researchers then stamp these individual flakes to target sites on a silicon wafer."
