    Abstract: An apparatus, a method, and a system are provided to calibrate an offset in an amplifier. The apparatus can include an amplifier, a voltage control unit, a comparator, and a processing unit. The amplifier can have four terminals: a positive differential input (VIN+), a negative differential input (VIN−), a positive differential output (VOUT+), and a negative differential output (VOUT−). The voltage control unit can be configured to adjust a first voltage on VOUT+ and a second voltage on VOUT−. The comparator can be configured to compare the first voltage on VOUT+ to the second voltage on VOUT− when VIN+ and VIN− are coupled to a common voltage. Further, the processing unit can be configured to provide a control signal to the voltage control unit based on the comparison of the first and second voltages on VOUT+ and VOUT−, respectively.

    Abstract: The invention relates to a device for coating a plurality of substrates (3) which are regularly arranged on a bearing surface (2) of a susceptor (1) associated to a process chamber (14), wherein the bearing surface (2) forms abutment flanks (5) for the edge mounting of each substrate (3). In order to reduce the free susceptor surface to a minimum, it is proposed that the abutment flanks of the lateral walls (5) are formed by bases (4) which project from the bearing surface (2) and are separated at a distance from one another. Said bases are arranged on the corner points (10) of a honeycomb structure and have an outline essentially corresponding to an equilateral triangle with inwardly curved sides (5).
