新材料與P溝道和N溝道晶體管的混合將有望使Intel公司制造出僅有目前芯片功耗10%的處理器。 Intel最近透露了一種P溝道晶體管進(jìn)展的細(xì)節(jié)，這種晶體管制作于硅基片上，采用混合半導(dǎo)體材料，也稱(chēng)作III-V材料，因?yàn)樗稍刂芷诒砩系谌泻偷谖辶械脑亟M成，而硅位于第四列。該研究的成果造就了迄今為止性能最優(yōu)的P溝道晶體管。 具Intel透露，這兩種結(jié)果結(jié)合在一起可以形成CMOS邏輯電路的基礎(chǔ)。CMOS邏輯電路同時(shí)采用N溝道和P溝道。這種技術(shù)有潛力用于制造將來(lái)的微處理 器，其工作溫度會(huì)低很多。Intel這個(gè)全球最大的芯片廠(chǎng)商聲稱(chēng)，新晶體管的工作電壓可降低50%，其功耗只有當(dāng)今晶體管的10%。 如果這種技術(shù)以后能夠?qū)崿F(xiàn)批量生產(chǎn)，那將產(chǎn)生兩種后果：一個(gè)事處理器尺寸非常小就能實(shí)現(xiàn)目前處理器的性能，或者同樣尺寸的處理器會(huì)非常復(fù)雜，功能會(huì)強(qiáng)大得多。顯然，該技術(shù)不僅會(huì)顯著降低微處理器的功耗，還會(huì)惠及圖形處理等高集成設(shè)備。 Intel目前正在繼續(xù)研究這項(xiàng)技術(shù)，據(jù)稱(chēng)尚需數(shù)年方可實(shí)現(xiàn)。 ---------------------- 原文： The mix of new materials as well as P-channel and N-channel transistors can potentially enable Intel Corp. to build microprocessors that consume just 10% of today’s chips in future. Intel recently disclosed advancement details on a P-channel transistor, built on a silicon substrate, that makes use of compound semiconductors, also known as III-V materials because they are made of elements that straddle silicon in the periodic table, silicon being in column IV. This research resulted in the highest performing P-channel transistors reported to date. A year earlier, Intel described III-V N-channel transistors, also built on a silicon substrate. According to Intel, when combined, these two results could form. the building blocks for CMOS logic circuits, which use both N-channel and P-channel transistors. Potentially suitable for future microprocessors, they run far cooler: the world’s largest chipmaker claims that t about 50% the voltage, consuming only 10% the power of today's transistors. Potentially, if the innovation proves to be viable for mass production of microprocessors, this enables either very small and power efficient chips which are powerful by today’s standards or chips that are dramatically more complex compared to contemporary, but consume the same amount of power. Obviously, the new materials can also enable dramatic improvements in energy efficiency not only for microprocessors, but also for graphics processors, core-logic sets and other highly-integrated devices. Currently Intel is already researching the aforementioned materials and it will take years before the innovation could materialize. |
