Title:
光電変換装置および機器
Document Type and Number:
Japanese Patent JP7250879
Kind Code:
B2
Abstract:
A photoelectric conversion apparatus includes a semiconductor layer including a photoelectric conversion portion, a charge holding portion configured to hold electric charge generated from the photoelectric conversion portion, and a charge detection portion to which the electric charge held by the charge holding portion is transferred. A gate electrode of a transistor and a light shielding film including a first portion covering the charge holding portion and a second portion covering an upper surface of the gate electrode are disposed above the semiconductor layer. The distance between the second portion of the light shielding film and the upper surface of the gate electrode is greater than the distance between the first portion of the light shielding film and the semiconductor layer.
