www.iare.ac.inSince the 1970s, the gate has been formed from polycrystalline silicon (polysilicon), but the name stuck. (Interestingly, metal gates reemerged in 2007 to solve materials problems in advanced manufacturing processes.) An nMOS transistor is built with a p-type body and has regions of n-type semiconductor adjacent to
