AmberWave Systems Corporation Announces Strained-Silicon-on-Insulator Breakthrough.SALEM, N.H. -- AmberWave Systems Corporation, the semiconductor industry's leading developer of strained silicon A technique that deposits silicon (Si) on top of silicon germanium (SiGe) for making transistors on a chip. In so doing, the silicon atoms are stretched ("strained") to line up with the silicon germanium atoms, which are wider apart. This causes less resistance in the silicon and increases performance. AmberWave Systems Corporation, Salem, NH (www.amberwave.com) is a pioneer in this technology. technology, today announced a breakthrough in strained silicon on insulator (SSOI SSOI - Summary Statement of Intent SSOI - Summary Statement Of Interest sSOI - Strained Silicon-On-Insulator (semiconductor wafers)) quality and manufacturability. Low manufacturing costs and high quality substrates are qualities that have historically been at odds--AmberWave Systems' breakthrough improves both simultaneously. Counterintuitively, AmberWave significantly improved the end quality of the SSOI substrate by starting with a silicon substrate intentionally laden with "threading" defects. The presence of these initial "threading" defects - generally acceptable in limited numbers - reduces both the number of "threading" defects in the final substrate by one order of magnitude A change in quantity or volume as measured by the decimal point. For example, from tens to hundreds is one order of magnitude. Tens to thousands is two orders of magnitude; tens to millions is three orders of magnitude, etc. and "dislocation complete dislocation one completely separating the surfaces of a joint. compound dislocation one in which the joint communicates with the air through a wound. congenital dislocation of the hip developmental dysplasia of the hip. pileups" in the final substrate by as much as three orders of magnitude. Dislocation pileups are a different type of defect which, in contrast to threading defects, are significant impediments to device performance and yield. AmberWaves' ability to eliminate dislocation pileups therefore marks a radical advancement in the quality of SSOI substrates. In addition to the quality improvement, this breakthrough also can be accomplished with a thinner strained silicon substrate, thereby significantly reducing growth time--the largest factor in fabrication expense. AmberWave's research demonstrated growth times of less than five minutes per wafer. This advancement furthers the industry's belief that wafer-scale strained silicon technology will continue to offer the semiconductor industry additional generations of strained silicon enhancement beyond those currently in production today. The research is the result of collaboration between Dr. Matthew Erdtmann and Dr. Matthew Currie of AmberWave and David Black and Joseph Woicik from the National Institute of Standards and Technology (NIST). Their findings will be presented on December 1 at the 2005 Materials Research Society (MRS) Fall Meeting held in Boston, Massachusetts from November 28 - December 2, 2005. Dr. Erdtmann will also chair the MRS Meeting Session 12 focusing on "Progress in Semiconductor Materials V - Novel Materials and Electronic and Optoelectronic Applications."
