WebPolycrystalline silicon, or multicrystalline silicon, also called polysilicon, poly-Si, or mc-Si, is a high purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry . Polysilicon is produced from metallurgical grade silicon by a chemical purification process, called the Siemens process. WebThese simulations show the importance of not defining the poly gate itself as the electrode when simulating MOSFETs. This would instruct the simulator to treat the poly-gate as a perfect conductor which would by definition not deplete. The accurate approach is to deposit metal onto the poly and define this metal layer as the electrode.
