IMAGE SENSOR STRUCTURES FOR FINGERPRINT SENSING |
| 摘要 |
Methods and systems for integrating image sensor structures with collimator filters, including manufacturing methods and associated structures for forming collimator filters at the wafer level for integration with image sensor semiconductor wafers. Methods of making an optical biometric sensor include forming a collimator filter layer on an image sensor wafer, wherein a plurality of light collimating apertures in the collimator filter layer are aligned with a plurality of light sensing elements in the image sensor wafer, and after forming the collimator filter layer on the image sensor wafer, singulating the image sensor wafer into a plurality of individual optical sensors. |
