  With the explosive growth in high-brightness LED (HB-LED) applications including backlighting and general illumination, device manufacturers are increasing focus on improved device performance and reduced manufacturing costs. In-line inspection during device fabrication significantly increases LED performance through improved process control and allows device makers to achieve cost savings through higher yields.  More

• Baolab Claims CMOS MEMS Breakthrough

  David Lammers, News Editor, March 8, 2010
  Baolab Microsystems (Barcelona, Spain) claims that is has developed manufacturing techniques that allow MEMS devices to be built within a standard CMOS process flow. The technique involves etching the IMD layers within the interconnect layers, said Baolab CEO David Doyle.  More

• Quake is Minor Disruption at TSMC, UMC

  David Lammers, News Editor, March 5, 2010
  An early Thursday earthquake in southern Taiwan caused minor damage at the Tainan chip fabs operated by foundries TSMC and UMC. Both reported that the company-wide impact would be limited to ~1.5 days, as the Tainan fabs underwent safety, maintenance and equipment checks. Several major producers of large LCDs also were impacted by the trembler.  More

• SEMI Seeks Input to Semicon Programs

  Paula Doe, SEMI, San Jose, March 2, 2010
  SEMI is seeking input this month for the technical programs held during Semicon West and Intersolar in July. Session agendas for the complex show need to be set by April and inputs are needed this month.  More

• IMEC Reports Record Organic RFID Circuit

  David Lammers, News Editor, February 17, 2010
  Researchers reported an organic TFT-based RFID circuit, with a record data rate and 10 V operation. The team, including researchers from IMEC, TNO and Polymer Vision, said the 64-bit transponder circuit has a data rate of 4.3 Kb/sec, twice as fast as the test circuit reported at last year's ISSCC. The team used a dual-gate design, with the top gate controlling the threshold voltage in the all-p-type technology.  More

• Phase Transition Research Points to New Devices

  Alexander E. Braun, Senior Editor, February 11, 2010
  Using carbon nanotubes, University of Washington scientists have devised a way to explore how phase transitions function in fewer than three dimensions and at the level of just a few atoms.  More

• Crystal Growth Points to Defect-Free Thin Films

  Alexander E. Braun, Senior Editor, February 1, 2010
  Cornell University researchers said colloidal research may lead to the discovery of principles that will enable the growth of defect-free thin films. The team led by Professor Itai Cohen tested conditions that lead to smooth crystal growth, and discovered that the random darting motion of the particles is a key factor affecting how crystals grow.  More
