Problems solved by technology

[0004] However, since the number of patterning processes directly affects the production cost and the yield rate, that is, the more the patterning process, the longer the production cycle, the higher the production cost, and the lower the yield rate. Therefore, how to reduce the The number of composition processes is a technical problem that needs to be solved urgently
