Fan-Out Wafer Level Packaging is the most innovative advanced packaging technology today, adopted for mobile phone and consumer electronics applications. Analysing the status of the patent situation is key to understanding the business situation.

ANALYSIS OF THE TECHNICAL CONTENT OF THE PATENT PORTFOLIO

After several years of specific analysis for customers, Yole Developpement has decided to publish its first analysis of the technical contents of patents: we have focused this first analysis on the FOWLP area, a new packaging technology which is changing the patent landscape for semiconductor packaging across a wide range of application spaces. Yole Developpement has developed a specific methodology to conduct our analysis (described below), mixing Yole Developpement technical and business knowledge with classical access to patent database.

A FEW COMPANIES WITH A LOT OF PATENTS, A LOT OF COMPANIES WITH A FEW PATENTS.

A complex patent landscape: 10 companies dominate the FOWLP IP space, but more than 120 organizations have patents in this field and represent 232 relevant patent families and 231 related patent families (Yole Developpement has discovered more than 1,000 patents). The analysis provides a database of all the relevant patents in an Excel file enabling multicriteria search. The criteria are basically those we used for the technological segmentation:

Patent information

  • Patent publication number
  • Title
  • Abstract
  • Assignee/applicant
  • Inventors
  • Priority date
  • Patent family relationships

FOWLP structure criteria

  • FOWLP toolbox detail or improvement (die placement, bonding, encapsulation, carrier
  • de-bonding, passivation, RDL, bumping,singulation)
  • Additional elements to the original process

Chip orientation

Carrier shape

Architecture details

  • 2D structures
  • MCP
  • 3D structures
  • PoP
  • PiP
  • Stacked dies
  • Use of vertical interconnects
  • TSV
  • TMV
  • Technology used
  • eWLB
  • RCP
  • PBP
  • Other

Packaged devices

It is also interesting to note that the size of the players involved in this area is variable. We can find large companies like TSMC as well as start-up and small players like Megica. The FOWLP IP space is studied from different angles and the analysis provides analysis of patents filled by these different kinds of players including the most recent assignees.

This complete description of the patent landscape is included in the first part of the analysis and provides all the background materials for the FOWLP patent landscape review. It also provides a complete analysis of the patent landscape including geographic origins of the patents, company or R&D organizations that have been granted the patents, historical data on when the companies have applied patents in the last 20 years, inventors of the patents, expiration status, R&D collaborations...

DETAILED ANALYSIS OF THE TOP 10 FOWLP PATENT ASSIGNEES

The analysis also provides a deep dive into each patent portfolio of the TOP10 patent assignees, including Infineon, ACE, Tessera, Samsung, Freescale, StatsChipPac, ASE, Amkor Technologies and STM. For each of these companies, the analysis provides an in-depth analysis of the patent portfolio of these companies, highlighting the following points:

  • Company patent portfolio evolution
  • Countries of deposition and origin of the patents
  • Top inventors
  • Process flow developed by the company (for commercially available devices)
  • Technical segmentation of each patent portfolio
  • Patent portfolio analysis for each manufacturing process steps and architecture
  • Main technical innovations
  • Which patents are used today in production, which patents are here to prepare the future generation of FOWLP technologies (multi dies, panel scale FOWLP, PoP FOWLP, TMV...)
  • Remaining challenges for the company from YOLE analysis

This analysis of each company provides an in-depth view of the strengths and weaknesses of the patent portfolio of each company and the developments that are now implemented by these companies.

UNIQUE TECHNOLOGY ANALYSIS OF THE PATENT CONTENT, IDENTIFICATION OF THE KEY PATENTS

Based on Yole Developpement analysis of the technology trends in FOWLP,the R&D of all the players worldwide and teardown of the devices in production, Yole Developpement have been able to identify and analyze the most important innovations for each process step of FOWLP, from die placement to encapsulation, passivation to bumping... For each part of the process steps of FOWLP, the analysis provides the related patents and the evidence of its use in real devices taking full benefit of teardown analysis provided by our partner System Plus Consulting. For example, a strong focus is made on Infineon's eWLB technology as well as on the 2nd generation FOWLP patents describing new architectures using the eWLB solution (please see also the full reverse analysis carried out by System Plus Consulting: Infineon Fan-out WLP Reverse Costing Analysis). As a synthesis, the analysis provides a ranking of the most important patents to highlight which of all the analyzed documents are blocking, which company owns such patents and the content of each patent.

METHODOLOGY OF THE ANALYSIS

Based on requests on Micropatent, and several other database, Yole Developpement has developed a unique methodology (described in the sample) to define a technical segmentation of the patent landscape and define which patents are the most innovative, either to prepare the future or to be used already in production. Yole Developpement, by mixing its technical knowledge, business understanding and patent search, is able to provide unique analysis and added value you will find in this analysis.

KEY FEATURES OF THE ANALYSIS

  • Presentation of the industrial and business status of the FOWLP today
  • Definition and delivery of a database of all the relevant patents with technological segmentation
  • Detailed architecture to be implemented
  • Identification of the key patents and the owner of such patents
  • Making links with the patents available and what has been implemented in production today.

WHO SHOULD BE INTERESTED IN THIS ANALYSIS

  • The executives of device makers and advanced packaging companies to look at the FOWLP business and the major patent evolutions that could impact the industry in the short, medium and long term
  • The technology and R&D teams of IDM, fabless and assembly service providers companies, looking to learn from the status of the patent landscape in the FOWLP fields
  • The end users, trying to understand the patent landscape of FOWLP before using it in their own systems or devices
  • The technology team of equipment and materials manufacturers involved in the FOWLP, looking to have a complete
  • picture of patent situation and the blocking patents.
