Observation of tracking camera cross-section by mechanical polishing.
Observation of the sensor chip surface, creating a cross-section through mechanical polishing in the mounted state, and conducting structural observation of the device!
We would like to introduce the "Tracking Camera Cross-Section Observation" through mechanical polishing. Regarding the structure of the tracking camera components, the lens can be confirmed when viewed from above, and while it cannot be clearly seen in the X-ray image, the lens is incorporated into the convex part. Additionally, the cross-sectional structure is the same as that of the RGB sensor, featuring a back-illuminated CMOS structure. However, since color information is not necessary for the tracking camera, there is no color filter layer. A jagged uneven shape was observed on the surface of the photodiode. 【Features】 ■ The cross-sectional structure is a back-illuminated CMOS structure, similar to that of the RGB sensor. ■ There is no color filter layer since color information is not needed for the tracking camera. ■ A jagged uneven shape was observed on the surface of the photodiode. *For more details, please download the PDF or feel free to contact us.
