Description

Technical Field

[0001] The present disclosure relates to the technical field of semiconductor packaging devices, and in particular to an antenna semiconductor packaging device and a manufacturing method thereof. Background Art

[0002] The current semiconductor packaging forms mainly include 2.5D packaging, 3D packaging and fan-out packaging. In 2.5D packaging and 3D packaging, the bare chip (Die) and the substrate in the packaged product are mainly connected by through silicon vias (TSV) and interposers. However, the through silicon via process of the interposer is long and expensive. Although fan-out packaging does not require an interposer with through silicon vias, it can be connected through metal pillars. However, there is a redistribution layer (RDL) between the bare chip and the bridge die, which will warp during thermal cycling. In addition, if the electronic components or circuit components (for example, bare chips) are arranged above and below in the fan-out package, the electronic components arranged in the lower layer may be displaced by the mold flow impact during the sealing process, which may cause the subsequent redistribution layer to be unable to accurately align the unique electronic components (for example, bare chips) produced due to the mold flow impact.

The figures have been simplified for better understanding of various aspects of the present invention.

[0125] The first step is to provide a first package.

[0126] like Figure 2A As shown, a first package body 21 is provided. Here, the first package body 21 includes a first carrier 22, a first wiring layer 10, a connecting wire 13 and a first electrical component 11.

[0127] The first circuit layer 10 has a first surface 10a and a second surface 10b opposite to the first surface 10a. The first circuit layer 10 can be bonded to the first carrier 22 through the second adhesive layer 27. The first carrier 22 can be a panel type or a wafer type. The first carrier 22 can include glass or other materials. The second adhesive layer 27 can be, for example, a temporary glue layer.

[0128] The first electrical component 11 is disposed on the first surface 10a. The passive surface of the first electrical component 11 is close to and parallel to the first surface 10a. The active surface of the first electrical component 11 is provided with an electrical connector.

[0129] The length of the connection line 13 is greater than the height of the first electrical component 11. The connection line 13 is electrically connected to the first circuit layer 10.

[0130] A second dielectric material 15 is disposed on the active surface of the first electrical component 11 and the end surface of the connecting line 13 away from the first circuit layer 10 to protect the active surface of the first electrical component 11 and the end surface of the connecting line 13 away from the first circuit layer 10 .

[0131] The electrical connectors and the connection lines 13 of the first electrical component 11 are exposed on a surface of the first package body 21 opposite to the first carrier 22 .

[0132] The second step is to place the circuit component on the first packaging body.

[0136] Here, a material with an automatic alignment property can be used to electrically connect the circuit component 12 to the first electrical component 11 and the connection circuit 13. As an example, the circuit component 12 can be flip-chip welded, hot-pressed welded, or reflow welded to the electrical connector of the first electrical component 11 and the circuit component 13. Among them, electrically connecting the circuit component 12 to the first electrical component 11 can be electrically connecting the circuit component 12 to the electrical connector provided on the active surface of the first electrical component 11.

For example, the bottom filling glue can be filled into the space below the circuit component 12 and between the first electrical component 11 and the connecting line 13 by dispensing technology to form the first dielectric material 14 for protecting the active surface of the circuit component 12. In some embodiments, the bottom filling glue can be a packaging material with smaller particles and better fluidity, which is used to fill small spaces.

[0140] In the fifth step, a packaging material is injected onto the circuit component to form a semiconductor packaging device.

In some embodiments, the circuit component can be electrically connected to the first electrical component, the connecting line and the second electrical component respectively by a material having an automatic alignment property. For example, the circuit component 12 can be flip-chip soldered, hot-pressed or reflow soldered to the electrical connector of the first electrical component 11, the electrical connector of the second electrical component 16 and the circuit component 13.

[0149] Based on the above optional implementation, in the fourth step, forming the first dielectric material between the circuit component and the first electrical component and the connecting circuit to protect the active surface of the circuit component can be performed as follows: forming the first dielectric material between the circuit component and the first electrical component and the connecting circuit, and forming the third dielectric material between the circuit component and the second electrical component to protect the active surface of the circuit component.
