Re: well proximity error
Hi,
In simple terms, any well will have non-uniform concentration of ions which is a process related issue, bcoz of which devices within this well will have different Vth depending on the placement of device wrt to the boundry of the well.
Hence we have to place the devices in close proximity to each other and preferably in the middle of the well or equidistant from the well boundry so that they dont differ much in the electrical parameters.
