Claim 41:
42. The device of claim 14, wherein the spacers have pillar shape, a predetermined substantially uniform height, and a predetermined constant inter-spacer distance, wherein the Young's modulus of the spacers times the filling factor of the spacers is equal or larger than 20 MPa, wherein the filling factor is the ratio of the spacer contact area to the total plate area, and wherein, for each spacer, the ratio of the lateral dimension of the spacer to its height is at least 1 (one), wherein the fourth power of the inter-spacer-distance (ISD) divided by the thickness (h) and the Young's modulus (E) of the plate (ISD4/(hE)) is 5×105 μm3/GPa or less, and wherein the thickness of a plate times the Young's modulus of the plate is in the range 60 to 750 GPa-μm.
