High density plasma deposition system was organized using electron cyclotron resonance source, and its plasma properties were measured by using the Langmuir probe method. The ECR microwave plasma conditions could be controlled by means of mass flow controller and ECR microwave power according to the vacuum pressure of 2.3×10^-5 Torr to 5.2×10^-2 Torr. The ion density was increased with an increase of gas flow rate, and a decrease of the distance between ECR source and substrates. The electron temperatures were decreased with an increase of gas flow rate, and a decrease of the distance between ECR source and substrates. The estimated plasma potential was from 27.0V to 31.5V
