Several focus monitoring methods for high volume manufacturing (HVM) have been developed to improve general tool stability maintenance, fleet matching and focus uniformity on product. One technique involving the usage of diffractive gratings requires special targets that need to be designed and optimized at the individual mask level, which will increase the development cycle time.
To explore the feasibility of ORP as the control parameter of one-stage completely autotrophic nitrogen removal system, this test studied the synthetic low C/N waste water, analyzed the correlation between the variation rule of concentration of ORP and the transfer of nitrogen compounds in system under different concentrations of DO. Results indicated that the ORP curve emerged a turning point when...
