Addressing Total Overlay Drift In Advanced IC Substrate (AICS) Packaging
By Keith Best - 07 Mar, 2023 - Comments: 0

For years, many in the semiconductor industry have focused on the march toward advanced nodes. As these nodes have decreased in size, the size of input/output (I/O) bumps on the chip has grown smaller. As these bumps shrink, their ability to mate directly to printed circuit boards (PCB) diminishes, which, in turn, leads to the need for an intermediary substrate. Enter the advanced IC substrate ... » read more

Effect Of RF Plasma Process Gas Chemistry And Electrode Configuration On The Removal Of Copper Lead Frame Oxidation
By Daniel Chir - 07 Feb, 2023 - Comments: 0

By Daniel Chir and Johnson Toh Lead frame surface oxidation can lead to surface delamination after molding or wire bonding issues. The application of plasma treatment has been proven to be safe and effective solution to address these issues. However, the effectiveness of plasma treatment for removing oxide is dependent on the correct use of recipe parameters, gas chemistry and electrode conf... » read more

An OSAT Perspective On Semiconductor Market Trends
By Vik Chaudhry - 19 Jan, 2023 - Comments: 0

For the semiconductor industry, 2022 was a very interesting year. On one hand, it witnessed shortages in the supply chain. On the other hand, the macro-economic situation turned and demand for several consumer and computing devices plummeted. A trade war with China and ensuing localization of supply chain with passage of CHIPS act took shape in 2022. The auto industry is still recovering from t... » read more

Mastering FOWLP And 2.5D Design Is Easier Than You Think
By Bill Acito - 22 Nov, 2022 - Comments: 0

IC packaging has come into its own, where once traditional packaging was a “necessary evil,” today’s packaging can add significant value. There is an increase in functional density and flexibility by providing a platform for heterogeneous design assembly. Where designs implemented in an SoC can become too large to yield satisfactorily and too difficult to implement on one process node, pa... » read more

Heterogeneous Chip Assembly Helps Optimize Medical And Wearable Devices
By Dick Otte - 17 Nov, 2022 - Comments: 0

Heterogeneous integration (HI) has significant implications for the medical, health, and wearables industry. At Promex, we utilize a variety of complex assembly processes to achieve HI for medical and biotech applications. This post will take a closer look at the processes associated with assembling these classes of devices. Figure 1 provides a high-level overview of our approach. Nearly eve... » read more

Research Bits: Nov. 15
By Jesse Allen - 15 Nov, 2022 - Comments: 0

Low temperature 3D bonding Scientists from Osaka University developed a new method for the direct three-dimensional bonding of copper electrodes using silver layers. The method works at low temperatures and does not require external pressure. "Our process can be performed under gentle conditions, at relatively low temperatures and without added pressure, but the bonds were able to withstand... » read more

Heterogeneous Integration: Correcting Overlay Errors On Advanced Integrated Circuit Substrates (AICS)
By John Chang - 08 Nov, 2022 - Comments: 0

By John Chang, with Corey Shay, James Webb, and Timothy Chang For high-performance computing, artificial intelligence, and data centers, the path ahead is certain, but with it comes a change in substrate format and processing requirements. Instead of relying on the quest for the next technology node to bring about future device performance gains, manufacturers are charting a future based inc... » read more

Heterogeneous Integration: Exposing Large Panels With Fewer Shots
By John Chang - 11 Oct, 2022 - Comments: 0

By John Chang, with Corey Shay, James Webb, and Timothy Chang The More than Moore era is upon us, as manufacturers increasingly turn to back-end advances to meet the next-generation device performance gains of today and tomorrow. In the advanced packaging space, heterogeneous integration is one tool helping accomplish these gains by combining multiple silicon nodes and designs inside one pac... » read more

Thermal Simulation Of DSMBGA And Coupled Thermal-Mechanical Simulation Of Large Body HDFO
By Nathan Whitchurch - 15 Sep, 2022 - Comments: 0

Electronic packaging has continued to become more complex with higher device count, higher power densities and Heterogeneous Integration (HI) becoming more common. In the mobile space, systems that were once separate components on a printed circuit board (PCB) have now been relocated along with all their associated passive devices and interconnects into single System in Package (SiP) style suba... » read more
