This paper reports a new method of amorphous layer deposition thanks traditional PECVD insulators equipments for seed layer performing. The main application of this method is the realisation of seed layer for EPIPOLY process without using LPCVD furnace. Amorphous layers are obtained thanks to traditional PECVD insulators equipment, AMT 5000, which allows to prevent LPCVD furnace from cross contamination. Furthermore AMT 5000 as single wafer equipment fits much better in ato research using. The major interest of the method is its compatibility with traditional microelectronic process and it involves very common PECVD equipment.
