Abstract

The invention provides a packaging structure and a manufacturing method thereof. The packaging structure comprises a substrate with a notch, and a first micro-electro-mechanical system chip, a first middle chip, a second micro-electro-mechanical system chip and a first cover plate which are sequentially formed on the substrate. The lower surface of the first micro electro mechanical system chip is provided with a first sensor or a micro actuator. The upper surface of the second micro electro mechanical system chip is provided with a second sensor or a micro actuator. The first middle chip is provided with a substrate through hole and comprises a signal conversion unit, a logic operation unit, a control unit or a combination of the signal conversion unit, the logic operation unit and the control unit. The package structure includes at least one of a first sensor and a second sensor.

Description

technical field [0001] The present invention relates to a package structure, and more particularly, to a package structure with a three-dimensional MEMS chip stack and a method for manufacturing the same. Background technique [0002] Microelectromechanical system (microelectromechanical system, MEMS) is a technology that combines microelectronics technology and mechanical engineering. MEMS technology enables the miniaturization of many industrial devices. The MEMS device usually includes a microprocessor and at least one miniature sensor for obtaining external information. [0003] For current MEMS devices, it is usually necessary to assemble multiple MEMS elements in the same package structure, and to integrate the operations of these MEMS elements. However, if the two MEMS elements are too close, their signals may interfere with each other. As a result, the yield and reliability of the MEMS device will be reduced. [0004] On the other hand, in the packaging structure...
