Description
SM520Square resistance tester is a new type of instrument for measuring semiconductor sheet resistance (surface resistance) according to similar national standards and American ASTM standards. It can be used to measure general semiconductor materials, conductive films (ITO transparent oxide film), metal films equal to the sheet resistance of the same species. The instrument takes large-scale integrated circuits as the main core; it uses a reference power supply and an operational amplifier to form a high-precision steady current source; it has an effective and normal indicator circuit with a loop; and is equipped with a large LCD display reading, which makes the instrument small in size, light in weight and beautiful in appearance. Easy operation, fast measurement speed and high precision. The instrument takes large-scale integrated circuits as the main core; it uses a reference power supply and an operational amplifier to form a high-precision steady current source;
