Abstract
Description
technical field
[0001] The invention discloses a vacuum coating device, in particular to a batch-processing PECVD device and method for producing low-cost and high-yield thin films on a large-area substrate. Background technique
[0002] The traditional plasma-enhanced chemical vapor deposition (PECVD) system is designed such that, in a glow discharge structure in which electrical energy is capacitively coupled into a pair of parallel electrodes, each excitation electrode (power electrode, also known as an energy supply electrode, Cathode or negative electrode) provide one, and usually only one corresponding coating surface. Figure 8 Shown is such a conventional parallel electrode glow discharge (PECVD) deposition apparatus. by Figure 8 For example: in the vacuum chamber 40 of the PECVD system, there are two planar electrodes with opposite polarities, which are respectively the excitation electrode 48 and the ground electrode 47, and these two parallel electrodes keep an a...
