Advanced Packaging Webinar Series Part I - Low Temperature Dielectric Deposition for Advanced Packaging
Advanced packaging continues to proliferate within semiconductor device manufacturing, offering performance benefits beyond those of front end of line (FEOL) CMOS gate length scaling only. Through silicon vias (TSV) and hybrid bonding both enable a shortening of the interconnect path with the lower resistance giving reduced parasitic losses and consequent higher device operating speeds and lower power consumption. These advanced technologies allow the stacking of die into 3D packages and so increase device functionality without any increase of package footprint; a particular benefit for mobile devices where low power consumption and small footprint are absolute requirements. An ever-increasing number of applications are realizing the benefits of such solutions, including stacked CPU and SRAM for logic and stacked DRAM for high bandwidth memory (HBM).
Dielectric materials are key building blocks in advanced packaging schemes, serving a number of quite different, but equally important, roles such as electrical isolation, passivation, bow compensation, bonding interface and inter-die gap-fill.
While spin-on dielectrics (SoD) are attractive because of their relatively low processing costs there are significant disadvantages to their use in an increasing number of packaging schemes relating to thermal budget, stress control, thickness control and compatibility with downstream process integration flows. Low temperature PECVD dielectric layers are increasingly preferred.
In this webinar we will demonstrate how high quality PECVD dielectric films can be deposited at temperatures as low as 100°C while maintaining high film quality and stability. We will then discuss the use of these films in a number of advanced packaging applications.
