SAMPLE AND METHOD FOR TESTING DETERGENCY

摘要

PURPOSE: A sample and a method for testing detergency are provided to reduce the time for developing a detergent and to accurately check the properties of a detergent by varying the elements contained in the detergent during a test. CONSTITUTION: A detergency testing sample(100) comprises a substrate(10), a gate electrode(20) formed on the substrate and made of a mono silicon doped with metal or ion, a gate insulating film(30) formed on the gate electrode and made of SiO2, a channel layer(40) formed on the upper face of the gate electrode and made of amorphous silicon or poly silicon, a source electrode(50) placed on the upper face of the channel layer and made of mercury, and a drain electrode(60) placed on the upper face of the channel layer and made of mercury.
