Many smartphone manufacturers are offering 5G handsets in a bid to increase mobile phone sales. Several 5G-compatible smartphones are in mass production and more are scheduled for release this year. Smartphones sales have stagnated so OEMs and carriers are pushing 5G development and deployment with the hopes that customers will be enticed to upgrade their phones.
These early 5G phones are primarily designed to enhance 4G LTE by adding sub-6GHz frequency spectrum. Support for the millimeter-wave (mmWave) version of 5G, which many consider to be the “true” 5G, is limited as rollout of the technology is still in its infancy.
By examining the design and construction of several 5G smartphones, TechSearch International has spotted important trends for the packaging industry, including more chips and packages in 5G handsets than 4G phones. For example, the Samsung Galaxy S10 5G has almost 2x more packages than the S10/S10+ for the RF front-end and baseband functions, and that is just to support sub-6GHz 5G connectivity. Additional RFFE packages are required for mmWave 5G.
TechSearch International’s latest Advanced Packaging Update provides details about RFFE designs and packages, transceiver and modem comparisons, and additional antenna and PMIC requirements for 5G handsets.
The latest Advanced Packaging Update also discusses packages found in basic feature phones. The report is 83 pages in length with full references and an accompanying set of 41 PowerPoint slides.
Driven by advanced packaging substrate needs, the industry has reached an inflection point in IC substrate manufacturing. Increasing I/O counts are driving substrate layer counts to more than 20. Larger die sizes and multiple die mounted on the substrate are driving the need for larger body sizes, up to 100 mm x 100 mm. Some companies use a silicon interposer with multiple redistribution layers (RDLs) to provide the connection between logic and high bandwidth memory (HBM). Others use fan-out on substrate with RDLs. A number of companies are considering new RDL on organic solutions with 2µm line width and spaces and Intel is exploring an expanded role for its Embedded Multi-die Interconnect Bridge (EMIB). Several companies are making investments in fab-like processing equipment for the next generation IC packaging substrates. These developments are described and a forecast for high-density substrates is provided in TechSearch International’s newest Advanced Packaging Update.
TechSearch International’s annual survey on substrate design rules is highlighted, with special coverage of suppliers of laminate flip chip BGA and CSP substrates worldwide. The design rules include body size, core thickness, via and pad diameter, minimum bump pitch supported, and substrate finish.
The latest Advanced Packaging Update is an 83-page report with full references and an accompanying set of 41 PowerPoint slides.
TechSearch International predicts strong market growth for fan-in wafer level packages (WLPs) and fan-out WLPs (FO-WLPs). Despite lower growth for smartphones, growth continues as the number of WLPs per handset increase. WLPs are increasingly adopted in tablets, and wearable devices such as smart watches, fitness bands, and virtual reality headsets. Fan-in WLPs are projected to grow at an 8.5% CAGR from 2018 to 2022. FO-WLP's adoption continues in products ranging from smartphones to automotive and the package shows a growth rate of almost 37% over the four-year period. Cost-reduction pressures are driving the development of alternatives to reconstituted wafer FO-WLP in the form of large area panel processing and the first product can be seen in the new Samsung smart watch. An analysis of the market growth in units, wafers, and panels is provided for fan-in and fan-out. The market is divided into standard-density, high-density, and panel.
TechSearch International’s new study, 2019 Flip Chip and WLP: Trends and Market Projections, provides detailed analysis of the drivers for fan-in WLP, FO-WLP, and flip chip. The detailed analysis is based on the company's 31-year history of studying markets and critical technology and infrastructure issues.
Demand for flip chip in applications ranging from large die for AI accelerators to small die for amplifiers and filters is provided. Cu pillar is increasingly used for many devices. Demand continues for both 300mm and 200mm bumping. Market projections in units and wafers are provided. Flip chip growth shows an 8.3% CAGR in unit volume from 2018 to 2022. Growth in gold bumping is also included. A critical analysis of planned capacity and utilization is provided for each geographic region, showing projections for strong growth in China.
The 124-page report with full references provides forecasts for the flip chip wafer bumping market by application, device type, number of wafers, and die shipments. Merchant and captive capacity is included. Forecasts for fan-in and FO-WLP demand are projected in number of die and wafer shipments. A set of 90 PowerPoint slides accompanies the report.
The high cost of moving to the next semiconductor technology node is changing the role of packaging and assembly in the electronics industry. Heterogeneous integration has become the solution to achieve the economic advantages that were previously met with silicon scaling. TechSearch International’s new report describes these packaging options, including silicon interposers, fan-out on substrate, and organic solutions such as Intel’s EMIB. Homogeneous packaging solutions such as AMD’s multichip package are also discussed. The report explains the reason for adoption in each application and provides market projections. A roadmap of future 3D packaging trends is presented and new concepts such as Intel’s Foveros are discussed.
Changes in RF package adoption are examined. Antenna-in-Package solutions for 5G are introduced and a market forecast is provided. A special section examines trends in 3D printing, highlighting printed antennas.
The latest Advanced Packaging Update is a 41-page report with full references and an accompanying set of 48 PowerPoint slides.
