Abstract: A method for forming a lift-off mask structure includes providing a substrate body, depositing a layer of bottom anti-reflective coating, BARC, over a surface of the substrate body, and depositing a layer of photosensitive resist over the BARC layer. The method further includes exposing the resist layer to electromagnetic radiation through a photomask, and forming the lift-off mask structure by applying a developer for selectively removing a portion of the BARC layer and of the resist layer such that an underlying portion of the surface of the substrate body is exposed.

Abstract: The peak comparator circuitry comprises a differential amplifier circuit having an output node to generate a differential amplifier output signal in response to an amplification of a difference of an input signal and a reference signal, and a comparator circuit having an output node to generate a comparator output signal. A feedback path of the peak comparator circuitry is arranged between the output node of the comparator circuit and the output node of the differential amplifier circuit. The proposed peak comparator circuitry allows for a low voltage supply, a low current consumption and a fast output validity.
