IBM to cool chips with H20

Technology are always improve day after day, and now is possible to cool the computer chip with water. As reported ad ZDnet.com, Scientists at IBM Zurich Research Lab and the Fraunhofer Institute in Berlin working on a microchip that uses micro tubes of water to cool, IBM announced this just yesterday. In electronic components are built in three-dimensional stack instead of parallel silicon water.

Water pumped a container refrigeration (purple in the image above) through the layers of a chip through the spaces directly integrated within the chips' structure (orange, above). Chips, developed in three-dimensional stack formation offer more paths for info to be processed and can shorten the distance electronic information must travel by as much as 1000 times, according to Thomas Brunschwiler, senior engineer at Advanced Thermal Packaging group at IBM Zurich Research Lab who is Chip work for almost two years.

The trouble, of course, is that this kind of experimental chip structure also generates a large amount of heat. To address the problem, the team has developed a system for cooling, consisting of micro water pipes as narrow as 50 microns - about as thin as a strand of human hair - these are interspersed between each chip layer. To prevent an electrical short, hair, as water pipes are hermetically sealed from other electronic components, first with silicon wall and then a layer of silicon oxide, said Brunschwiler.

Scientists have used alloys consisting of a mixture of gold and tin, which has a low melting point, to bond holders of individual tubes from layer to layer, not disrupt other electronic components. For use in supercomputers, the chip is five to ten years away were not available. It should be noted that this is not the first time water is preparing to come on board for cooling.

As many of you are aware, companies such as IBM and Hewlett-Packard sells server racks with liquid cooling systems. Researchers from the Tyndall Institute in Cork and Limerick University announced in March that they work in a liquid included in the cooling system of packaging that encases chips. And in April IBM supercomputer announced, which uses water along with its processors to cool them.

AMD speed up the Production, to Cut down the Costs

AMD as the second world's largest producer of x86 processors a rough year, with the failed product launches and delays in the course of his roadmap. They face Lack of sales, which together with the loss of profit; the company was on the brink of bankruptcy. They have arranged the company policies, in order to survive and to provide the next generation of processors.

According to a Lehman Brothers Holdings Inc. analyst, the company announced plans to transfer more production in the next two to three months to reduce costs. The company earned 13 cents, or 1.9 percent, at $ 6.96 in New York Stock Exchange composite trading. The analysts of the company met in the last week CFO Robert Rivet. "AMD is still much on the drafting of a plan on the basis of assets," said analyst Tim Luke, immediately after the meeting. "Developing an advantage given the critical attitude is of strategic importance for AMD, the tensions on the balance sheet," he added.

The Chief Executive Officer Hector Ruiz argued that the company is working on the possibilities for reducing the expenditure of plans for the semiconductor industry in the (or fabs), because they cost the company about $ 3 billion for the construction and Equipment for the production. Ruiz has refused to reveal Advanced Micro Devices for the next steps, because by the "active smart strategy" could be its competitors in the market for processors (Intel) to undermine their plans for the company.

However, the analysts who participated in the meeting, it was determined that the manufacturer of the chips could even the sale of its investments in semiconductors, outsourcing or even the entire production to other companies such as Taiwan Semiconductor Manufacturing.

"We are looking for ways to the burden of our capital on our balance sheet through partnerships such as the ones we deal with IBM," said AMD spokesman Drew Prairie. "We are trying to do, the relationship with similar, but as in the manufacturing industry," says Wiese.
