    • The invention provides a method and apparatus for calculating gate length and source/drain gate overlap, by measuring gate capacitance. The invention uses previously known fringe capacitance C.sub.fr and unit capacitance C.sub.OX. The invention measures gate capacitance C.sub.g, when the gate is accumulatively biased, and solves for overlap capacitance C.sub.OV using the equation C.sub.OV =(C.sub.g -2C.sub.fr)/2 or C.sub.OV =(C.sub.gg -C.sub.gb -2C.sub.fr)/2. The invention then measures the gate capacitance C.sub.g when the gate to source/drain voltage is set to inversion bias and a zero voltage is applied between the source/drain and the substrate, and solves for the channel capacitance C.sub.ch using the equation C.sub.ch =C.sub.g -2C.sub.fr -2C.sub.OV. The invention calculates the channel capacitance C.sub.ch where C.sub.ch =C.sub.g -2C.sub.fr -2C.sub.OV and then calculates gate length where gate length L.sub.g =(2C.sub.OV +C.sub.ch)/C.sub.OX and the effective gate length L.sub.eff =C.sub.ch /C.sub.OX. The invention further calculates source/drain gate overlap L.sub.OV, by setting L.sub.OV =C.sub.OV /C.sub.OX.
    • 本发明提供了一种通过测量栅极电容来计算栅极长度和源极/漏极栅极重叠的方法和装置。 本发明使用先前已知的边缘电容Cfr和单位电容COX。 本发明在栅极被累积偏置时测量栅极电容Cg,并使用公式COV =(Cg-2Cfr)/ 2或COV =(Cgg-Cgb-2Cfr)/ 2求解重叠电容COV。 然后,当栅极/源极/漏极电压被设置为反向偏压并且在源极/漏极和衬底之间施加零电压,并且使用公式Cch = Cg-1求解沟道电容Cch时,本发明测量栅极电容Cg。 2Cfr-2COV。 本发明计算Cch = Cg-2Cfr-2COV的沟道电容Cch,然后计算栅极长度Lg =(2COV + Cch)/ COX和有效栅极长度Leff = Cch / COX的栅极长度。 本发明通过设定LOV = COV / COX,进一步计算源极/漏极栅极重叠LOV。
