Abstract
A sensor package structure and method is characterized in connecting a sensor with a circuit substrate in a flip chip bonding method to enhance the structure strength and miniaturize the product; using a no-flow underfill glue to fill the gap between the sensor and the circuit substrate to protect the contacts of the flip chip structure, prevent the performance from being affected by the overflowing encapsulant, and promote the reliability of products. The present invention uses the no-flow underfill glue process to replace the processes of forming a dam and a soft protection layer and thus simplifies the fabrication process and reduces the fabrication cost.
