Oki Integrates AlGaAs LEDs on Silicon Mounting Chips Kenji Tsuda, Asia Contributing Editor - 04/24/2008
Oki Digital Imaging Corp. is in mass production with LED print heads that use a film bonding technique to integrate AlGaAs epitaxial layers on CMOS silicon ICs. The approach avoids wasting valuable space on bonding pads, resulting in higher-density arrays for LED print heads, Oki managers said at the INC4 conference in Tokyo. More
Researchers Advance CNT-Based Networks Staff - 07/24/2008
In what appears to be a major advance in carbon nanotube-based circuits, researchers from Purdue University and the University of Illinois at Urbana-Champaign said they have succeeded in building networks of carbon nanotubes (CNTs). The team solved the problem of metallic CNTs causing short circuits by cutting the network into precise strips. The effort could advance the field of flexible circuits and displays, they said.

Solid-State Lighting Becoming Practical Paula Doe, Contributing Editor, SEMI - 07/15/2008
Semiconductor-based lighting could cut the energy used by lighting in half, says the U.S. Department of Energy (DOE, Washington, D.C.). Because lighting accounts for about one-fifth of all electricity used in the United States, that could add up to some $98B in energy savings by 2020.
