    • Provided is a circuit to perform single-ended to differential conversion while providing common-mode voltage control. The circuit includes a converter to convert a single-ended signal to a differential signal and a stabilizing circuit adapted to receive the differential signal. The stabilizing circuit includes a sensor configured to sense a common-mode voltage level of the differential signal and a comparator having an output port coupled to the converter. The comparator is configured to compare the differential signal common-mode voltage level with a reference signal common-mode voltage level and produce an adjusting signal based upon the comparison. The adjusting signal is applied to the converter via the output port and is operative to adjust a subsequent common-mode voltage level of the differential signal.

    • The invention relates to a device for coating substrates having a process chamber (1) disposed in a reactor housing and a two-part, substantially cup-shaped susceptor (2, 3) disposed therein, forming an upper susceptor part (3) with the cup floor thereof having a flat plate (2) and a lower susceptor part (3) with the cup side walls thereof, the outer side (4) of the plate (2) of the upper susceptor part (2) facing upwards toward the process chamber (1) and forming a contact surface for at least one substrate, the upper susceptor part (2) contacting a front edge (3′) of the lower susceptor part (3) at the edge of said upper susceptor part (2), the lower susceptor part (3) being supported by a susceptor carrier (6), and heating zones (A, B, C) for heating the upper susceptor part (2) being disposed below the plate (2′). An advantageous refinement of the invention proposes that the upper susceptor part (2) be removable from the process chamber (1) separately from the lower susceptor part (3), and the joint between the edge of the upper susceptor part (2) and the front edge (3′) of the lower susceptor part (3) be formed as a heat conduction barrier.
    • 本发明涉及一种用于涂覆基材的装置,其具有设置在反应器壳体中的处理室(1)和设置在反应器壳体中的两部分基本杯形基座(2,3),形成上基座部分(3),其中 其底板具有平板(2)和具有杯侧壁的下基座部分(3),上托架部分(2)的板(2)的外侧(4)朝向处理 并且形成用于至少一个基板的接触表面,所述上基座部分(2)在所述上基座部分(2)的边缘处接触下基座部分(3)的前边缘(3'), 下基座部分(3)由基座托架(6)支撑,加热区(A,B,C)用于加热设置在板(2')下方的上基座部分(2)。 本发明的有益改进提出,上基座部分(2)可以与下基座部分(3)分离地从处理室(1)移除,并且上基座部分(2)的边缘与 下感受器部分(3)的前边缘(3')形成为导热屏障。
