AI Technical Summary

Problems solved by technology

If the substrate is a single-layer circuit system, the routing capability is limited, but if the substrate is a multi-layer circuit system, its excessively thick dielectric layer will reduce the heat dissipation effect
In addition, the previous technology has problems such as insufficient heat sink performance, too large volume, or difficult thermal connection to the next layer of semiconductor chipset.
The manufacturing process of the prior art is also not suitable for low-cost mass production operations

Abstract

The invention relates to a semiconductor chip assembly with a post / base heat spreader and a cavity over post. The semiconductor chip assembly at least includes a semiconductor device, the heat spreader, the substrate and an adhesive. The semiconductor device is electrically connected to the substrate and thermally connected to the heat spreader. The heat spreader at least includes a post and a base. The post extends upwardly from the base into an opening in the adhesive and an aperture in the substrate, and the base extends laterally from the post. The adhesive extends between the post and the substrate and between the base and the substrate. The assembly provides signal routing between a pad and a terminal.

Description

technical field [0001] The invention relates to a semiconductor chip assembly body, more specifically, a semiconductor chip assembly body with semiconductor elements, wires, adhesive layers and heat sinks and a manufacturing method thereof. Background technique [0002] Existing semiconductor components such as packaged and unpackaged semiconductor chips can provide high-voltage, high-frequency and high-performance applications; these applications require high power consumption to perform specific functions, but the higher the power, the semiconductor Components generate more heat. In addition, after the packaging density is increased and the size is reduced, the surface area available for heat dissipation is reduced, which leads to serious accumulation of heat energy. [0003] Semiconductor components are prone to problems such as performance degradation and shortened service life under high temperature operation, and may even fail immediately. High heat not only affects ...
