Oh wow, this is really cool. I've seen the exact patterns under 'thin film buckling' (Ziebert et al., “Strongly buckled square micromachined membranes,” J MEMS 8 423-432, 1999) when fabricating ~25nm x50umx50um thick, edge-supported, square membranes of SiN. It always seemed a little crazy that something so delicate could distort that much and remain intact. |
