Problems solved by technology

[0017] Furthermore, although the surface resistivity of the parts in contact with the substrate such as the glass substrate in the substrate cassette is controlled at 10 6 -10 14 Ω / □ range, but the glass substrate will be self-charged when it is in contact with or separated from the substrate box, which will cause breakdown of the circuit formed on the glass substrate, because the glass substrate is an insulator

[0083] The present invention will now be described more specifically but not exclusively with reference to Examples and Comparative Examples. Physical properties were measured as described below.

[0084] (1) Surface resistivity

[0085] The surface resistivity is 1.0×10 6 For samples of Ω / □ or larger, a constant voltage meter (Model 300-1A, manufactured by Kikusui Corporation), an ammeter (Model 616, manufactured by Keithley Corporation) and a sample cell (Model 1608A, manufactured by Yokogawa-HP Made by the company) Measured according to JISK-6911 when a voltage of 100V is applied, and the surface resistivity is less than 1.0×10 6 The sample of Ω / □ was measured in accordance with JISK-7194 using Loresta HP manufactured by Mitsubishi Chemical Corporation.

[0086] (2) Charge amount of glass substrate

[0087] The surface potential of the glass substrate after being in contact with the sample was measured at a temperature of 23°C and a relative humidity of 50% with a surfa...
