Abstract
In some examples, a device comprises a substrate including a notch formed in a surface of the substrate and a semiconductor die positioned in the notch and including an electrochemical sensor on an active surface of the semiconductor die. The device also comprises a chemically inert member abutting the surface of the substrate and including an orifice in vertical alignment with the electrochemical sensor as a result of the semiconductor die being positioned in the notch. The device also comprises a compressed o-ring seal positioned between the chemically inert member and the active surface of the semiconductor die, the compressed o-ring seal circumscribing the electrochemical sensor.
Claims18
A device comprising:
- a first substrate;
- a semiconductor die including an electrochemical sensor positioned on a first surface of the semiconductor die, the first surface electrically coupled to and facing the substrate;
- a chemically inert member attached to the first substrate;
- and
- a ring positioned between the chemically inert member and the first surface of the semiconductor die;
- and
- a battery coupled to the first substrate via a conductive terminal, the battery facing a second surface of the semiconductor die that is opposite the first surface.
A device comprising:
- a substrate including a notch;
- a semiconductor die including an electrochemical sensor on a first side of the semiconductor die, a portion of the semiconductor die in the notch, the semiconductor die electrically connected to the substrate;
- a ring contacting the first side and circumscribing the electrochemical sensor;
- and
- a chemically inert member contacting the ring and the substrate, the chemically inert member including an orifice in vertical alignment with the electrochemical sensor.
