With the rapid development of electronic technology, power consumption is increasingly becoming a limiting factor in the realization of VLSI systems. Low-voltage design, low-current design and corresponding software and hardware design in low-power design have become competing researches by companies. Important areas. At the "IC Design Seminar" held on March 18, green design has almost become synonymous with product competitiveness.

    Peter Yeung from Hong Kong Hi-Tech Park introduced process analysis methods for high-efficiency devices, such as chip delamination processing technology, focused ion beam (FIB), structural analysis technology, etc.

   "In the future 22nm era, the metal line width is getting smaller and smaller, and the spot area of ​​the ion beam is required to be small enough. This will be a challenge for detection and analysis technology." Peter Yeung said.

   "Designing a more energy-efficient system is urgent," VeriSilicon President and CEO Wayne Dai emphasized when talking about the necessity of low-power design. "Electronic technology enables us to connect to the Internet at any time and manage the increasingly complex life. But each kind of equipment used for connection is more and more power-consuming, and green chip design is imperative."

    The ever-increasing functional requirements of electronic products have led to the market demand for more complex and highly integrated silicon products. Overcoming design challenges, optimizing development budgets, and shortening time to market are the keys to meeting the needs of electronic product applications.

    For many Foundry, the design of the chip directly determines the complexity of the process and the final product performance. How to combine the design with the manufacturing process is one of the problems faced by the Foundry. "The main design challenges that Foundry faces are: applications for portable products, such as battery life extension and rapid growth in computing speed; high-performance applications, such as power limitation and device cooling, etc." said James Wei of SMIC, "Currently There are already more than 1 billion computers in use worldwide, and low-power design is the development direction of chip technology. "In the field of IC manufacturing, industry insiders have been experimenting with new materials and new processes. For the reduction of power consumption, their applications are also very beneficial. For example, the use of SOI technology can reduce power consumption by about 20%, and the research on metal gates and high-k materials has also brought a lot of progress in low power consumption. Opportunity.
