Claim:
1. A hot plate comprising: a first barrier layer; a first heat transfer layer on the first barrier layer; a second barrier layer on the first heat transfer layer, a second heat transfer layer on the second barrier layer; and a third barrier layer on the second heat transfer layer; wherein the first barrier layer, the second barrier layer, or the third barrier layer includes a plurality of first sub-nano-barrier layers and a plurality of second sub-nano-barrier layers; wherein the first heat transfer layer or the second heat transfer layer includes a silicon carbide (SiC) layer or a hafnium nitride (HfN) layer; wherein the first and second barrier layers are in direct physical contact with the first heat transfer layer; wherein the second and third barrier layers are in direct physical contact with the second heat transfer layer; wherein each first sub-nano-barrier layer is in direct physical contact with at least one of the second sub-nano-barrier layers and each second sub-nano-barrier layer is in direct physical contact with at lease one of the first sub-nano-barrier layers; and wherein each first sub-nano-barrier layer and each second sub-nano-barrier layer has nanoscale size.
