Topology for Substrate Routing in Semiconductor Package Design


Abstract: In this work, we propose a new signal routing method for solving routing problems that occur in the design process of semiconductor package substrates. Our work uses a topological transformation of the layers of the package substrate in order to simplify the routing problem into a problem of connecting points on a circle with non-intersecting straight line segments. The circle, whi... » read more

Impact Modifiers and Compatibilizers for Versatile Epoxy-Based Adhesive Films with Curing and Deoxidizing Capabilities


Abstract: "Epoxy resins with acidic compounds feature adhesion, robustness, and deoxidizing ability. In this study, hybrid adhesive films with deoxidizing and curing capabilities for semiconductor packaging were fabricated. The compatibilizing effects and mechanical properties were chiefly investigated by using various additive binders (thermoplastic amorphous polymers) and compatibilizing a... » read more

X-ray Imaging of Silicon Die Within Fully Packaged Semiconductor Devices


Abstract: "X-ray diffraction imaging (XRDI) (topography) measurements of silicon die warpage within fully packaged commercial quad-flat no-lead devices are described. Using synchrotron radiation, it has been shown that the tilt of the lattice planes in the Analog Devices AD9253 die initially falls, but after 100 °C, it rises again. The twist across the die wafer falls linearly with an incre... » read more

TAP-2.5D: A Thermally-Aware Chiplet Placement Methodology for 2.5D Systems


Abstract "Heterogeneous systems are commonly used today to sustain the historic benefits we have achieved through technology scaling. 2.5D integration technology provides a cost-effective solution for designing heterogeneous systems. The traditional physical design of a 2.5D heterogeneous system closely packs the chiplets to minimize wirelength, but this leads to a thermally-inefficient design... » read more

A Review on the Fabrication and Reliability of Three-Dimensional Integration Technologies for Microelectronic Packaging: Through-Si-via and Solder Bumping Process

Holistic Die-to-Die Interface Design Methodology for 2.5-D Multichip-Module Systems


Abstract: "More than Moore technologies can be supported by system-level diversification enabled by chiplet-based integrated systems within multichip modules (MCMs) and silicon interposer-based 2.5-D systems. The division of large system-on-chip dies into smaller chiplets with different technology nodes specific to the chiplet application requirement enables the performance enhancement at the ... » read more

A review of interconnect materials used in emerging memory device packaging: first- and second-level interconnect materials


Abstract "The main motivation of this review is to study the evolution of first and second level of interconnect materials used in memory device semiconductor packaging. Evolutions of bonding wires from gold (Au) to silver (Ag) or copper (Cu) have been reported and studied in previous literatures for low-cost solution, but Au wire still gives highest rating in terms of the performance of tempe... » read more

Research on Wire Sweep of Integrated Circuit Packaging Based on Three-dimensional Flow Simulation


Abstract: "Semiconductor manufacturing technology is becoming more and more rapidly. In the process of Integrated Circuit (IC) encapsulation, when wires contact each other, it will cause short circuit. Wire sweep has become the main factor affecting the reliability of the product. Therefore, it is a great challenge to master wire sweep in IC packaging process. This paper takes Low Profile Fi... » read more
