Two level charge imaging matrix design with stepped insulator |
摘要 |
The disclosure relates to a charge imaging matrix wherein the floating gate level closest to the substrate is used as a storage gate and the second floating gate level is used as both a field plate and a transfer gate due to the formation of a step in the insulator thereunder which leaves an N-channel in the transfer region when the remainder of the gate is biased to flat band.
