Description

Yole SORAA LED GaN on GaN iconeflyerNew in this LED: GaN substrate, triangular shape chip, simplified epitaxial structure and an original silicon-based wafer level packaging

SORAA has recently released the first GaN on GaN LED in a 50W halogen equivalent MR16 lamp with several new features.

SORAA smartly used the GaN characteristics like the optical transparency and the high electrical and thermal conductivity to create a unique vertical structure for these LEDs. The layers deposited by epitaxy are very thin.

A high current density per sq cm is obtained, estimated at 120A / sq cm. The SORAA LEDs have a triangular shape to limit the internal reflection of the light and thus increase the light extraction.

An original silicon package with a multilayer mirror is used to increase the light extraction of the LED lamp.

This report provides a complete teardown of the LED and the package with:

  • Detailed photos
  • Material analysis
  • Detailed structure of dies and package
  • Manufacturing Process Flow
  • In-depth economical analysis
  • Manufacturing cost breakdown
  • Selling price estimation

SYSTEM PLUS CONSULTING

Across the Enterprise, from marketing to purchasing and R&D, product manufacturing cost is a major factor which has to be measured and then optimized. Since 1993, System Plus Consulting’s mission has been to develop and sell the right tools and services to meet these costing requirements.

System Plus Consulting utilizes an engineering approach to cost. Cost models and technology expertise are combined to provide customers with an accurate and objective estimation of manufacturing costs and selling prices.

Headquartered in Nantes, France, System Plus Consulting is specialized in technology and cost analysis of electronic components and systems. During our 20 years in business, we have built and refined detailed cost models as the primary tools for hundreds of analyses. The highly qualified System Plus cost engineers combine broad and deep skills in semiconductor and electronics technologies with years of experience in cost modeling.

We offer:
− Custom reverse costing analyses: technology analysis followed by cost evaluation
− Standard reverse costing reports: regular publications on innovative products (available from our catalogue)
− Costing tools: software tools combining models and data to perform cost analysis

System Plus Consulting analyzes any type of electronic devices and systems, with a special focus on semiconductor technologies. Major fields of technology and cost expertise are:
− Integrated Circuits
− Power Devices and Modules
− MEMS & Sensors
− Photonics: LED, Image Sensors
− Packaging including wafer level
− Electronic Boards and Systems

Our analyses are used by Purchasing Departments to measure their suppliers’ cost structure, R&D Departments to confirm technological choices depending on their impact on costs, and Benchmarking/Marketing Departments to monitor the products on the market.

System Plus Consulting is committed to provide a high level of service:
− Delivery of reports and custom analyses with a minimum lead time.
− Results presentation and online Q&A sessions when support is needed.
− Open methodology and full confidentiality in order to maintain a trustful collaboration.

Since 2008, our partnership with YOLE Développement has allowed us to stay at the forefront of technologies and has added a market view to our reports.
