Abstract
The inventive concept provides an image sensor including a step having a slope shape and an image sensor including the wafer-to-wafer bonding structure. The image sensor includes a first substrate including a pixel array, a first multilayer wiring, a first insulation layer formed on a first junction surface to pass through the first insulation layer and a second substrate on the first substrate, wherein the second substrate includes a logic circuit, a second multilayer wiring, a second insulation layer on a second junction surface opposite to the first junction surface and a second metal pad passing through the second insulation layer, and a second step formed in the second junction surface engages with a first step formed in the first junction surface in a symmetrical slope shape to form direct bonding between the first substrate and the second substrate.
