Problems solved by technology

[0003] QFP (Quad Flat Package) is a surface-mount package. The connection between the internal chip and the board level is completed by leading out pins of different shapes on the four sides. Because the size of the carrier table used to place the chip in the QFP middle frame is related to the size of the chip The number of pins is closely related, so it limits the feasibility of implementing SiP with QFP
Currently, frame-type packaging is usually used to realize SiP. However, when completing SiP packaging, the size of different components will seriously restrict the packaging density. Especially for thinner products, the number of packageable components becomes the frame-type packaging to carry forward SiP technology more serious problems

Abstract

One embodiment of the invention provides a multi-chip framework package structure which includes at least one carrier table, at least one bottom chip and at least one upper chip. The at least one carrier table is used for accommodating the at least one bottom chip and the at least one upper chip. The package structure further includes at least one first medium layer which is disposed above the atleast one bottom chip. The at least one upper chip is disposed above the at least one first medium layer. The position relationship between the at least one bottom chip and the at least one upper chipcan be adjusted by adjusting the tilt angle of the at least one first medium layer, so that the number of chips stacked on the at least one carrier table can be increased. The other embodiment of theinvention provides a manufacturing method of the multi-chip framework package structure.

Description

technical field [0001] The invention relates to semiconductor device packaging technology, in particular to a multi-chip frame packaging structure and a manufacturing method thereof. Background technique [0002] Today, with the gradual development of electronic engineering, miniaturized, lightweight and functional integrated circuit (IC) chips are becoming more and more popular. Moreover, as the semiconductor industry's crystal garden process is about to reach the bottleneck, packaging technology will become an important role in improving chip manufacturing profits and challenging Moore's Law. Under this huge demand, semiconductor packaging density will continue to increase. From the development of one component, it has gradually entered the stage of integrating multiple components into a system. As a multi-chip packaging technology, system-in-package (SiP) is the current and future development trend of packaging technology. Its packaging forms are diverse, and according ...
