Method of determining the doping concentration across a surface of a semiconductor material
A method (100) of determining a doping concentration of a semiconductor material (101) includes the steps of moving carriers (102) in the material, wherein a number of carriers is a function of the doping concentration of the material (101). The carriers are deflected (130) toward a surface (110) of...

| description | A method (100) of determining a doping concentration of a semiconductor material (101) includes the steps of moving carriers (102) in the material, wherein a number of carriers is a function of the doping concentration of the material (101). The carriers are deflected (130) toward a surface (110) of the material (101) and an accumulated charge profile on the surface of the material, due to the deflected carriers, is detected (140) and used to calculate (180) the doping concentration across a surface (110) of the material (101). |
