Current Characterization Of Various Cu RDL Designs In Wafer Level Packages (WLP)


Copper (Cu) redistribution layer (RDL) technology is used to interconnect chips in various high current Wafer Level Packaging (WLP) applications. Typically, Cu RDLs with thicknesses of 5-9 µm and widths of 5-20 µm are used for high current sourcing. In this case, the temperature of the Cu RDL metal line increases due to the Joule heat generated when current passes through the metal line. If a... » read more

A Hybrid PLP Technology Based On A 650mm x 650mm Platform


A panel-level (PL) approach to fan-out (FO) packaging has been discussed for several years to reduce the cost of chip-first FO packaging based on redistribution layer (RDL) technology. More recently, multilayer high-density chip-last packages have been introduced for more advanced applications. This technology would also benefit from PL processing for cost reduction. Due to the large package di... » read more

A Single-Layer Mechanical Debonding Adhesive For Advanced Wafer-Level Packaging


Better performance and lower cost are always key trends being pursued in the semiconductor industry. Moore's law has provided a very well-defined relationship between performance and cost and the semiconductor industry has followed this law for the past several decades with no issue. However, it became more and more difficult for foundries and integrated device manufacturers (IDMs) to scale to ... » read more

A Novel Multifunctional Single-Layer Adhesive Used For Both Temporary Bonding And Mechanical Debonding in Wafer-Level Packaging Applications


Temporary bonding (TB) and debonding (DB) of wafers have been widely developed and applied over the last decade in various wafer-level packaging technologies, such as package-on-package (PoP), fan-out integration, and 2.5D and 3D integration using through-silicon vias (TSVs). The materials used to achieve TB and DB are extremely critical and the industry's current best practice is the use of tw... » read more

End In Sight For Chip Shortages?


The current wave of semiconductor and IC packaging shortages is expected to extend well into 2022, but there are also signs that supply may finally catch up with demand. The same is true for manufacturing capacity, materials and equipment in both the semiconductor and packaging sectors. Nonetheless, after a period of shortages in all segments, the current school of thought is that chip suppl... » read more

Scaling Bump Pitches In Advanced Packaging


Interconnects for advanced packaging are at a crossroads as an assortment of new package types are pushing further into the mainstream, with some vendors opting to extend the traditional bump approaches while others roll out new ones to replace them. The goal in all cases is to ensure signal integrity between components in IC packages as the volume of data being processed increases. But as d... » read more

System-In-Package Thrives In The Shadows


IC packaging continues to play a big role in the development of new electronic products, particularly with system-in-package (SiP), a successful approach that continues to gain momentum — but mostly under the radar because it adds a competitive edge. With a SiP, several chips and other components are integrated into a package, enabling it to function as an electronic system or sub-system. ... » read more
