    Abstract: A method for forming a well providing access to a sensor pad includes patterning a first photoresist layer over a dielectric structure disposed over the sensor pad; etching a first access into the dielectric structure and over the sensor pad, the first access having a first characteristic diameter; patterning a second photoresist layer over the dielectric structure; and etching a second access over the dielectric structure and over the sensor pad. The second access has a second characteristic diameter. The first and second accesses overlapping. A diameter ratio of the first characteristic diameter to the second characteristic diameter is not greater than 0.7. The first access exposes the sensor pad. The second access has a bottom depth less than a bottom depth of the first access.

    Abstract: In one implementation, a chemical sensor is described. The chemical sensor includes a chemically-sensitive field effect transistor including a floating gate conductor having an upper surface. A dielectric material defines an opening extending to the upper surface of the floating gate conductor. A conductive element on a sidewall of the opening and extending over an upper surface of the dielectric material.

    Abstract: In one embodiment, a chemical sensor is described. The chemical sensor includes a chemically-sensitive field effect transistor including a floating gate conductor having an upper surface, a first opening extending through a first material and through a portion of a second material located on the first material and a second opening extending from the bottom of the first opening to the top of a liner layer located on the upper surface of the floating gate conductor.

    Abstract: A method of forming a sensor component includes forming a first layer over a sensor pad of a sensor of a sensor array. The first layer includes a first inorganic material. The method further includes forming a second layer over the first layer. The second layer includes a polymeric material. The method also includes forming a third layer over the second layer, the third layer comprising a second inorganic material; patterning the third layer; and etching the second layer to define a well over the sensor pad of the sensor array.
