Description

Yole Infineon CoolMOS C7 May 2014 IconeFlyerInfineon has improved the epitaxy process with a direct impact on Rdson, 20% lower

The CoolMOSTM C7 from Infineon is the 7th generation high-voltage Superjunction structure power MOSFET. With a breakdown voltage of 650V for a current of 7A (100°C), the C7 is optimized for hard switching topologies such as Power Factor Correction, solar boost circuit applications.

The CoolMOSTM C7 offers a very low on-resistance (between 19mΩ and 225mΩ), and a fast switching speed, more than 100KHz. The C7 differs from the C6 via a new multi-epitaxy technology and an original contact solution. The C7 wafer cost is 10% higher than the C6 but the current density is 25% higher and the power losses 20% lower.

This reverse costing report provides an estimation of the production cost of the IPD65R225C7, a discrete CoolMOSTM transistor.

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.
