| description | Systems and methods for non-contact characterization of semiconductor devices. Systems may include: an infrared radiation source directing radiation towards the semiconductor device; a radiation directing device positioned proximal the infrared radiation source to direct radiation towards an opposing side of the semiconductor device, the semiconductor device receivable between the radiation directing device and the infrared radiation source; and a radiation detector proximal to the infrared radiation source to sense radiation associated with a plurality of infrared wavebands from the semiconductor device for determining a dopant profile property of the semiconductor device. The sensed radiation may include radiation originating from the infrared radiation source reflected from the semiconductor device. The sensed radiation may include radiation originating from the radiation directing device and emerging from the semiconductor device. The dopant profile properties may be based on infrared reflectance or infrared transmittance associated with the plurality of respective infrared wavebands. |
