An individual memory cell is made up of one planar polysilicon layer containing a hole filled by multiple concentric vertical cylinders.
Construction Growth of a group of V-NAND cells begins with an alternating stack of conducting (doped) polysilicon layers and insulating silicon dioxide layers.
Because polysilicon is a semiconductor, its work function can be modulated by adjusting the type and level of doping.
Compared to the traditional Siemens process, FBR features a number of advantages that lead to cheaper polysilicon demanded by the fast-growing photovoltaic industry.
Furthermore, because polysilicon has the same bandgap as the underlying silicon channel, it is quite straightforward to tune the work function to achieve low threshold voltages for both NMOS and PMOS devices.
Amorphous polysilicon is used in photovoltaic devices.
