Abstract:
The application disclosed a semiconductor image sensor and a preparation method thereof. The semiconductor image sensor includes: a semiconductor substrate, a buffer layer formed on the semiconductor substrate; and a potential regulation laminated structure, formed on the buffer layer, and configured to regulate a surface potential of the semiconductor substrate. The potential regulation laminated structure includes a first potential regulation layer formed on the buffer layer, a second potential regulation layer formed on the first potential regulation layer and a third potential regulation layer formed on the second potential regulation layer, wherein the first potential regulation layer includes a high-k dielectric constant material layer, and the second and third potential regulation layers each include either a conductive material layer or a high-k dielectric constant material layer.

Claim (Index 20):
The preparation method for a semiconductor image sensor according to  claim 19 , wherein after annealing, the method further comprises a step of forming an anti-reflection layer on the dielectric protection layer and annealing the obtained structure.
