Assume the capacitor areas of top and tunnel oxide are identical, which of the following statements is NOT true about designing oxide thickness?

The White Cliffs of Dover are composed mainly of: A: Calcium Carbonate B: Silicon Dioxide C: Mangan Oxide D: Iron Oxide

What is NOT true about the thermal oxide layer? A: A thermal oxide layer can serve as a passivation layer. B: A thermal oxide layer acts as an insulator and forces the electrons to flow in the emitter. C: It creates a back surface field at the back side of the solar cell and thus it reduces the surface recombination velocity. D: The oxide layer can be thermally grown.
