ABSTRACT:
The present invention relates to a process for depositing a calcium getter thin film inside a system operating under vacuum. The process comprises the steps of introducing into the system under vacuum at least one evaporable getter device with an air-stable calcium compound. The system is evacuated until a pressure value P1is reached. The system is then heated up to the calcium evaporation temperature of the stable compound. The system evacuation continues until a pressure value P2, which is lower than P1, is reached and the system is sealed. In a preferred embodiment, the heating step separates the two evacuation steps.
