Abstract

The invention discloses a semiconductor chip stacking structure. A plurality of first chips are stacked, the first chips are arrayed in a stepped stacking manner, a dielectric board is arranged on the first chip on the uppermost layer, a second chip is further arranged on the dielectric board, the first chips are upwards and electrically connected with the dielectric board firstly, and then the dielectric board is electrically connected to a bottom substrate. Therefore, the dielectric board can collect the signals of all chips and transmit the signals to the bottom substrate through less electrical connecting components (such as conducting wires), the number of connecting pads needed by the substrate is relatively reduced, so that the length and width of the substrate can be reduced, and further, the stacking density of the chips is increased, and the packaging size is reduced.

Description

technical field [0001] The present invention relates to a semiconductor chip stacking structure, in particular to a semiconductor chip stacking structure with an interposer. Background technique [0002] Nowadays, in order to meet various demands of high-density packaging, the semiconductor packaging industry gradually develops various types of packaging structures, among which various system in package (SIP) design concepts are often used to construct high-density packaging structures. Generally speaking, the system package can be divided into multichip module (multichip module, MCM), package on package (package on package, POP) and package in package (package in package, PIP). The multi-chip module (MCM) refers to arranging several chips on the same substrate. After setting the chips, the same packaging gel is used to embed all the chips, and it can be subdivided into stacked chips (stacked die) according to the arrangement of the chips. ) package or parallel chip (side-b...
