GlobalFoundries今天宣布將會開發(fā)20nm半導體制造工藝，但與臺積電不同，新工藝將與22nm共存，而且GF認為這種半代工藝并不會消失。臺積電不久前剛剛宣布，將跳過22nm工藝， 改而直接上馬更先進的20nm工藝，采用增強型高K金屬柵極(HKMG)、應變硅、低電阻銅超低K互聯(lián)等技術(shù)，可帶來更高的柵極密度和芯片性能。在此之 前，臺積電和GF還先后宣布將跳過32nm Bulk工藝，從40nm直奔28nm。 GF目前的業(yè)務主要有兩種，一是繼續(xù)為AMD制造微處理器，二是開拓新的代工業(yè)務，為其他芯片廠商代工更簡單一些的各類芯片，這就需要新的制造工 藝，特別是半代工藝。 GF公關(guān)總監(jiān)Jon Carvill表示：“我們在同時投資于22nm和20nm工藝。半代工藝的需求肯定會不斷增長，同時也有微 處理器業(yè)務等大規(guī)模市場需要全代工藝。” 他同時指出：“現(xiàn)在談論從28nm轉(zhuǎn)向22/20nm工藝所能獲得的確切性能和能效還為時過早。隨著(晶體管)幾何尺寸的變小，工藝進步的幅度也同 樣如此，但這并不意味著(新工藝)沒有此前工藝世代的好處或者更簡單。” Jon Carvill還強調(diào)說：“在市場上保持半導體工藝的領先需要面臨成本和復雜性兩方面的挑戰(zhàn)。開發(fā)新的領先工藝會耗資數(shù)十億美元，建設新工廠也要花費40 多億美元(Fab 2)。這些巨額開銷會讓很多企業(yè)望而卻步，可能會帶來更多合并，以及更多企業(yè)放棄自家生產(chǎn)的模式。” 編譯/驅(qū)動之家 |

他們的后臺老板死了，不知有何影響。 Gulf sheikh Ahmed bin Zayed al-Nahyan found dead in Morocco The boss of the Abu Dhabi Investment Authority (ADIA), the world's biggest sovereign wealth fund, has been found dead in Morocco. By Louise Armitstead, Chief City Correspondent Published: 6:59PM BST 30 Mar 2010 Gulf sheikh Ahmed bin Zayed al-Nahyan was ranked 27th on the Forbes list of the most powerful people in the world Photo: EPA Sheikh Ahmed bin Zayed al-Nahyan, who directed ADIA's recent acquisition of 15pc of Gatwick Airport, was found four days after his glider aircraft went missing. He was 40. ADIA, which is thought to have assets worth $627bn (£420bn), declined to comment.

However, sources close to the fund said that a succession plan is being worked on. Ranked 27th on the Forbes list of the most powerful people in the world, Sheikh Ahmed was also a half-brother of Sheikh Khalifa bin Zayed al-Nahyan, Abu Dhabi's ruler and the president of the United Arab Emirates. Sheikh Ahmed took control of ADIA in 1997 where he was described as "very hands on" in investment decisions. The sovereign wealth fund's most high-profile investment was a stake of about 4pc in Citigroup. It invested $7.5bn into the US investment bank in November 2007 at the beginning of the financial crisis, and as the economic situation worsened the relationship soured. Last year ADIA filed an arbitration claim against Citi, alleging it was the victim of "fraudulent misrepresentations" at the time of the investment. ADIA alleges that the numbers Citi gave it were incorrect. Citi says the claims are without merit. Although fiercely private, Sheikh Ahmed was considered an active proponent of improving the transparency of sovereign wealth funds. ADIA co-chaired a group of powerful funds that penned the so-called San Diego Principles, the first code of conduct for sovereign wealth funds. This month, ADIA released its first annual review, in which it stated its 20-year and 30-year annualised rate of return to the end of 2009 was 6.5pc and 8pc, respectively. Abu Dhabi's Ministry of Presidential Affairs has announced three days for mourning during which the flags will be flown half mast with effect from tomorrow. |
