Problems solved by technology

[0002] In the preparation process of the existing fan-out packaging structure with antennas, it is usually necessary to directly arrange a semiconductor chip on the circuit substrate. Conventionally, the semiconductor chip is connected to the semiconductor chip through a wire bonding process or a flip chip process. The circuit substrate is electrically connected, and then a plastic sealing resin layer is set on the semiconductor chip, and an antenna structure is further set on the plastic sealing resin layer. The above preparation process is likely to cause the antenna structure to be unstable, and then it is easy to peel off and fall off.

Abstract

The invention relates to a fan-out package with an antenna and a preparation method thereof, and relates to the field of semiconductor package. The first antenna structure and the second antenna structure are formed in the first preset antenna pattern and the second preset antenna pattern in a mode of spin-coating the metal nanowire solution, and the implementation of the preparation process is convenient for improving the bonding tightness of the antenna structures and the flexible resin packaging layer, so that the antenna structures can be prevented from stripping and falling off. Furthermore, the first antenna structure and the second antenna structure are stacked and electrically connected with each other, so that the signal transmitting strength of the antenna structure or the signal receiving capability of the antenna structure is effectively improved, and the functionality of fan-out packaging is improved.

Description

technical field [0001] The invention relates to the field of semiconductor packaging, in particular to a fan-out package with an antenna and a preparation method thereof. Background technique [0002] In the preparation process of the existing fan-out packaging structure with antennas, it is usually necessary to directly arrange a semiconductor chip on the circuit substrate. Conventionally, the semiconductor chip is connected to the semiconductor chip through a wire bonding process or a flip chip process. The circuit substrate is electrically connected, and then a plastic sealing resin layer is set on the semiconductor chip, and an antenna structure is further set on the plastic sealing resin layer. The above preparation process is likely to cause the antenna structure to be unstable, and then easy to peel off and fall off. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a...
