Fingerprint Sensor in InFO Structure and Formation Method - A simplified explanation of the abstract
This abstract first appeared for US patent application 18348460 titled 'Fingerprint Sensor in InFO Structure and Formation Method
Simplified Explanation
The patent application describes a package that includes a sensor die and an encapsulating material.
- The top surface of the encapsulating material is either at the same level or higher than the top surface of the sensor die.
- The package also includes a plurality of sensing electrodes that are higher than both the sensor die and the encapsulating material.
- These sensing electrodes are arranged in rows and columns and are electrically connected to the sensor die.
- A dielectric layer is used to cover the sensing electrodes.
Original Abstract Submitted
A package includes a sensor die, and an encapsulating material encapsulating the sensor die therein. A top surface of the encapsulating material is substantially coplanar with or higher than a top surface of the sensor die. A plurality of sensing electrodes is higher than the sensor die and the encapsulating material. The plurality of sensing electrodes is arranged as a plurality of rows and columns, and the plurality of sensing electrodes is electrically coupled to the sensor die. A dielectric layer covers the plurality of sensing electrodes.
