Abstract:
1. A plasma doping apparatus for doping materials by using plasma for a substrate, comprising: a first chamber group having a first plasma doping chamber for doping a first impurity material and a second plasma doping chamber for doping a second impurity material; a first delivering mechanism configured to deliver the substrate to or from the first plasma doping chamber; and a second delivering mechanism configured to deliver the substrate to or from the second plasma doping chamber, wherein; all components of the first and second delivery mechanisms are completely separated from each other by a partition wall, the first and second plasma doping chambers are disposed in a transfer chamber, the first plasma doping chamber is configured to carryout P-type doping and the second plasma doping chamber is configured to carryout N-type doping, and the first and second plasma doping chambers are separated from each other and are disposed in a closed space.
