Abstract
The present disclosure relates to a circuit board, a semiconductor device, an imaging device, a solid-state image sensor, a method for manufacturing a solid-state image sensor, and an electronic apparatus that suppress a decrease in characteristics and a yield. A step portion formed on a substrate surface is configured in a divided state. With this configuration, a photoresist liquid dropped in a lithography process flows through a gap between the divided step portions so that the photoresist liquid uniformly flows on an imaging surface, whereby a decrease in characteristics and a yield due to application unevenness can be suppressed. The present disclosure can be applied to a solid-state image sensor.
