[0034] Example 1 Doping under the condition of water and oxygen atmosphere
[0035] The present embodiment relates to a process including P-type channel doping by a solution method in a water-oxygen atmosphere and a method for fabricating a polymer field effect transistor, which specifically includes the following specific steps:
[0036] 1) Substrate cleaning: a glass sheet is used as the substrate. Put the glass pieces into beakers of deionized water (DI) and ethanol respectively, use an ultrasonic cleaning machine to clean them for 5-10 minutes, repeat the operation 2 times, and then use high-purity nitrogen (purity 99.99%) to clean the glass pieces. The surface was blown dry, and the glass sheet was thoroughly dried by heating at 100 °C for 20 minutes on a heating table, and used as a substrate;
[0037] 2) Surface treatment: Clean the dried glass sheets with an ultraviolet ozone cleaning machine (U / V ozone) for 30 minutes to remove organic residues on the surface of the ...
