Toshiba LED GaN on Si flyerFirst high brightness LED GaN-on-Silicon with 160lm per watt, almost equivalent to sapphire LED Base

Toshiba has completely changed its technology to multiply by 2 the brightness of their GaN-on-silicon LEDs. Today the Toshiba white LEDs have characteristics close to the classic sapphire LED with a smaller cost. The large panel of products and packages available todaya shows the maturity of Toshiba products and their willing to conquer the white LED market.

With a footprint of 3.5x3.5mm, the TL1L4-WH0 from Toshiba is tiny and benefits of the last package innovations like the sintering and a SMD leadframe with ceramic substrate and take full benefit of strong innovations. The TL1L4 LED are produced on a cheap 8” silicon substrate in a standard power silicon facility from Toshiba.

The integration in a standard facility has been facilitate by a gold-free smart bonding process. A significant work has been done on the epitaxial layer in GaN to enhance the brightness. In 18 months, the brightness has been multiplied by 2. The optimization of the GaN epitaxy is the core of this amazing improvement. Moreover, all the manufacturing process has been enhanced to reach this brightness.

Today the Toshiba white LEDs are similar to the last sapphire LEDs with a vertical thin film with via structure. The report includes a detailed technology and a cost analysis describing the  innovations of Toshiba and a comparison with the first generation Toshiba LED. LED on silicon can now compete against LED on Sapphire.

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.
