Poly gate deposition
WebPolysilicon, poly-Si, or polycrystalline silicon, is a material consisting of a number of smaller crystals or crystallites. Deposition of polysilicon is one of the most important CVD … WebThis leads to uniform etching of the amorphized poly and, therefore, disappearance of the oxide pillars. ... FIG. 1A shows the initial device structure through deposition of the undoped gate polysilicon layer 100. As shown in FIG. 1B, a layer of POCl 3 film 102 is then deposited over the undoped polysilicon 100.
