Abstract: An integrated sensor and method for manufacturing the sensor includes a first component having a first material with a predetermined first value of coefficient of thermal expansion (CTE), and a second component over the first component. The second component includes a second material with a predetermined second value of CTE different from the first value. An interlayer is provided by molecular layer deposition, for minimizing stress caused by coefficient of thermal expansion mismatch between the first and second components. The interlayer includes an organic-inorganic hybrid polymer compound.

Abstract: A method of manufacture of a sensor and a sensor for sensing a magnetic field generated by a current in a conductive substrate includes a first substrate having a sensing element for sensing magnetic field, and a second substrate is the conductive substrate. A conformal layer is provided by atomic layer deposition between the first substrate and the second substrate, thus protecting at least the sensing element from discharge from the second substrate.

Abstract: A lead frame for a current sensor is provided. The frame includes a conductive piece with an average thickness, and a sensing zone for generating a signal detectable by a current sensing element when current flows through the lead frame. It also includes a routing zone outside the sensing zone for routing current towards the sensing zone. The routing zone comprises a region with the largest area having a predetermined average thickness. At least the sensing zone includes additional material disposed on the conductive piece so the total thickness of the sensing zone is thicker than the average thickness of said largest area.
