Compact sensor module

摘要

A compact sensor module and methods for forming the same are disclosed herein. In some embodiments, a sensor die is mounted on a sensor substrate. A processor die can be mounted on a flexible processor substrate. In some arrangements, a thermally insulating stiffener can be disposed between the sensor substrate and the flexible processor substrate. At least one end portion of the flexible processor substrate can be bent around an edge of the stiffener to electrically couple to the sensor substrate

主权项

1. A sensor module comprising:
a first substrate and a second substrate; a sensor die in electrical communication with the first substrate and the second substrate; a processor die in electrical communication with the first substrate and the second substrate; and a stiffener having a first side and a second side opposite the first side, wherein the first and second sides of the stiffener include major surfaces of the stiffener, the stiffener disposed between the sensor die and the processor die such that the first side faces the sensor die and a first normal line passes perpendicularly through the major surface of the first side and intercepts the sensor die, and such that the second side faces the processor die and a second normal line passes perpendicularly through the major surface of the second side and intercepts the processor die, wherein one of the first and second substrates includes a bent portion and a mounting portion extending from the bent portion, the bent portion folded around an edge of the stiffener to electrically couple the sensor die and the processor die, and wherein the processor die is directly mounted to one of the first and second substrates and the sensor die is mounted over the other of the first and second substrates, and wherein the stiffener is further disposed between a first portion of the first substrate and a second portion of the second substrate, such that the first normal line intercepts one of the first portion and the second portion and the second normal line intercepts the other of the first portion and the second portion.
