    • The invention is based on the object of reducing the heating of substrates during plasma enhanced chemical vapor deposition. For this purpose, a method and an apparatus for coating substrates by means of plasma enhanced vapor deposition are provided, in which at least part of the surroundings of the substrate surface of a substrate to be coated is evacuated and a process gas with a starting substance for the coating is admitted, wherein the coating is deposited by a plasma being ignited by radiating in electromagnetic energy in the surroundings of the substrate surface filled with the process gas. The electromagnetic energy is radiated in in the form of a multiplicity of pulse sequences, preferably microwave or radiofrequency pulses, with a multiplicity of pulses spaced apart temporally by first intermissions, wherein the electromagnetic energy radiated in is turned off in the intermissions, and wherein the intermissions between the pulse sequences are at least a factor of 3, preferably at least a factor of 5, longer than the first intermissions between the pulses within a pulse sequence.
    • 本发明基于在等离子体增强化学气相沉积期间减少衬底的加热的目的。 为此,提供了一种通过等离子体增强气相沉积来涂覆基板的方法和装置,其中待涂覆的基板的基板表面的至少部分周围环境被抽真空,并且具有起始物质的处理气体 对于涂层是允许的,其中通过在填充有工艺气体的衬底表面的周围的电磁能中辐射的等离子体来沉积涂层。 电磁能以多种脉冲序列的形式辐射,优选为微波或射频脉冲,其中多个脉冲通过第一次间隔在时间上间隔开,其中辐射的电磁能在中断期间被关闭,并且其中 脉冲序列之间的间隔至少比脉冲序列内脉冲之间的第一次间隔长3倍,优选至少5倍。
