Latest Patents

Mori holds a patent for LED light source probe card technology designed for testing CMOS image scan devices. This technology provides improved wafer-scale testing of optoelectronic devices. The probe card features an LED light source corresponding to each device under test on the wafer. The LED light sources emit light from a phosphor illuminated by the LED. A pinhole and lens arrangement is utilized to collimate the light directed to the devices under test. The uniformity of illumination is achieved through closed-loop control of the LED light sources, using internal optical signals as feedback, combined with calibration data that relates optical signal values to emitted optical intensity. Additionally, the uniformity can be enhanced by incorporating a neutral density filter for each LED light source, which improves consistency from one source to another and enhances the radiation pattern from each LED light source.
