preparation example Construction

[0054] The preparation steps of the thin film field effect transistor 37 include:

[0055] Step 1: Deposit tungsten-doped indium oxide thin film on the glass substrate, using DC reactive magnetron sputtering coating process, sputtering current is 120mA, sputtering voltage 300-320V, sputtering at room temperature for 15min, to obtain the thickness of tungsten-doped indium oxide thin film 100nm;

[0056] Step 2: Prepare Al source-drain electrodes, using thermal evaporation process, when the vacuum degree is lower than 3×10-3Pa, turn on the evaporation power supply, heat the tungsten boat to evaporate Al, the evaporation current is 120mA, and the time is 1.5min to ensure that the prepared Al The electrode sheet resistance is less than 5Ω, the thickness is 100nm, and the resistivity is lower than 3×10-5Ω·cm;

[0057] Step 3: Prepare the PVP grid dielectric layer, dissolve polytetravinylphenol powder in absolute ethanol solution, stir until completely dissolved to obtain a solutio...

Embodiment approach

[0059] As a preferred embodiment, the first step includes the following steps:

[0060]Step 1.1: Immerse the glass substrate in an acetone ultrasonic bath for 10 minutes, then place it in fast-flowing warm water for 5 minutes, and finally wash it with deionized water for 5-10 minutes until a uniform water film is formed on the surface of the glass substrate;

[0061] Step 1.2: immerse the glass substrate in absolute ethanol and ultrasonically clean it for 15 minutes;

[0062] Step 1.3: Take out the glass substrate and place it in deionized water for ultrasonic cleaning for 10 minutes, then take out the glass substrate and dry it in a constant temperature oven at 120°C;

[0063] Step 1.4: Introduce argon and nitrogen, the total working pressure is 0.35Pa, keep the flow ratio of argon and nitrogen at 2:1, and use DC reactive magnetron sputtering to obtain the tungsten-doped indium oxide film with a thickness of 100nm .

[0064] This embodiment also provides an elevator control...
