Semiconductor device and method of manufacture
An image sensor includes a photosensitive sensor, a floating diffusion node, a reset transistor, and a source follower transistor. The reset transistor comprises a first source/drain coupled to the floating diffusion node and a second source/drain coupled to a first voltage source. The source follower transistor comprises a gate coupled to the floating diffusion node and a first source/drain coupled to the second source/drain of the reset transistor. A first elongated contact contacts the second source/drain of the reset transistor and the first source/drain of the source follower transistor. The first elongated contact has a first dimension in a horizontal cross-section and a second dimension in the horizontal cross-section. The second dimension is perpendicular to the first dimension, and the second dimension is less than the first dimension.
