Liquid-filled chips cool like mini-fridges Published: April 18, 2005, 6:19 AM PDT By Michael Kanellos Staff Writer, CNET News.com Purdue University can put a refrigerator in the palm of your hand. Researchers at the university's mechanical engineering department are testing out "microchannel heat sinks" that could cool components inside lasers, weapons or future computers with a series of channels filled with chilled, circulating fluids. The newfangled heat sinks only take up about 1 square inch of space, meaning that several could fit into tight spaces to draw away heat. The channels inside the device that carry the liquid measure about 300 microns in diameter. Microfluidics--making chips, or chip-sized devices, with small coils for circulating liquid--is moving from a futuristic curiosity toward a compelling potential market. ST Microelectronics, Intel and Pria Diagnostics have created microfluidic chips for preparing patient biological samples that could replace today's expensive lab procedures and equipment. "Some of these microfluidic devices are little chemistry laboratories on a chip," said Intel co-founder Gordon Moore in a recent interview. Purdue's heat sinks work like refrigerator coils. Cool liquid circulates toward a hot spot, absorbs heat, and then leaves, only to circulate back after a trip through a compressor. (Using a similar technology but in a very different way, Boston Microsystems has created a chip with microchannels that can heat up to 1,100 Celsius in 1/1,000th of a second) One of the challenges in the Purdue project was that materials behave differently inside a small device. Fluids flow differently in microchannels than they do in larger tubing, and bubbles form differently, which changes how heat is dissipated. "You have to design new systems to pump coolants through these microchannels and develop new mathematical tools to predict how well designs will perform," Issam Mudawar, a professor of mechanical engineering said in a statement. Removing heat from PCs has become a major problem for chipmakers and PC manufacturers. The latest Apple G5 desktop comes with a liquid cooling system. However, the system adds about $50 to the cost of a computer, said Dan Hutcheson, CEO of market research company VLSI Research. Start-up Cooligy is creating a similar system for PCs that use chips from Intel and Advanced Micro Devices.

TI expects semi market to strengthen after weak quarter Spencer Chin EE Times (04/18/2005 5:13 PM EDT) MANHASSET, N.Y. — Texas Instruments Inc. posted net earnings of $411 million, or 24 cents per share on sales of $2.97 billion in the first quarter of 2005, compared to $490 million, or 28 cents per share on sales of $3.15 billion in the previous quarter. Texas Instruments (Dallas, Texas) met the revised guidance it issued in March, warning of sagging semiconductor demand, particularly for its DLP (Digital Light Processing) products. On a positive note, TI's gross margin rose 2.6 percent to 44.9 percent, and operating margin increased 1.3 percents to 16.7 percent. The company continued to reduce its inventory levels as well. "The market environment is improving," said Rich Templeton, TI's president and chief executive, in a statement."We believe the inventory correction in TI's standard semiconductor products at distributors that began in the third quarter of 2004 is complete, as demonstrated by sequential growth in revenue and orders for these products." TI's first-quarter capital expenditures were $277 million, up $66 million sequentially but down $124 million from a year ago. The expenditures funded mostly equipment for 65- and 90-nm wafer fabrication, and assembly and test operations. The company expects 2005 capital expenditures of $1.3 billion. For the second quarter, TI sales of $3 billion to $3.3 billion, with earnings of per share of 25 to 29 cents.
