Description

technical field [0001] The invention belongs to the field of plasma technology, in particular to a device for depositing thin films by microwave plasma. Background technique [0002] With the application of microwave plasma in the preparation of semiconductor thin film materials, and semiconductor thin film materials, especially liquid crystal display materials and solar cells, tend to have large areas (> 30cm 2 ) development, the production of large area (> 30cm 2 ) Semiconductor thin film materials are the development direction of the future semiconductor industry, especially liquid crystal display materials and solar cells. [0003] However, the traditional capacitively coupled plasma (CCP) is far from meeting the requirements. There are several different methods for microwave-induced plasma discharge: [0004] (1) The microwave energy is coupled with the plasma generator. For example, a horn antenna with a window is used to separate the device into high and low ...
