Package
Board
Ceramic, looks like Al2O3. Two layers of metalization plus thick-film resistors. Blue dielectric may be glass or polymer, not sure which yet.
Die
One layer of polysilicon resistor plus one layer of gold metalization.
Die is <100> oriented as can be seen by the KOH (or similar) etch used to define the cavity under the membrane.
