為了向中國的工程師群體分析和報道中國IC設計公司的運營狀況和研發水平,《電子工程專輯》已經連續9年運作“中國IC設計公司調查”,一路伴隨和見證中國IC設計產業的發展。2010年,我們繼續通過電子郵件和電話追訪的方式,向珠三角、長三角、環渤海以及正在中部、西部地區崛起的462家IC設計公司發出了問卷,最終獲得174家公司的完整回復,有效回復量比去年增長了7%。

今年的調查數據顯示,72%的IC公司的雇員少于200人,70%公司的IC設計師少于60人。而73%的公司銷售額少于5千萬美元,其中少于1百萬美元的公司就占到21%,而銷售額介于1百萬至1千萬以及一千萬至5千萬之間的公司則各占26%。大部分本土IC公司的規模依然較小,然而,注意到一些本土公司的實力和銷售額正發生巨大變化。此外,中國龐大的市場和低廉的勞動力成本也正吸引越來越多的國外半導體公司來大陸設立其子公司或設計中心。

表示提供全系統設計服務的公司比例依然強勁。本刊分析的原因是,迫于市場競爭的激烈,客戶產品的面市壓力很大,全系統設計服務前景仍然看好。而MTK的成功更是繼續刺激著本土IC企業的神經,因此我們有理由相信,本土IC設計業者未來幾年將不斷復制“MTK模式”。特別地,越來越多的主控芯片供應商會推出多媒體平臺產品。

隨著本土IC設計產業的蓬勃發展,中國大陸也成為了EDA廠商和半導體代工廠競爭最激烈的陣地。

數據表明,本土無晶圓IC公司(Fabless)與大陸、臺灣地區的半導體代工廠商保持穩定的合作關系。回復者認為最適合他們產品的前四大代工廠分別是中芯國際(SMIC)、臺積電(TSMC)、華虹NEC以及聯電(UMC)。

毫無疑問,成本和交貨周期是本土IC設計公司和代工廠主要的供需矛盾,這將是長期的博弈過程。與代工廠合作過程的主要困難中,今年變化最大的是“生產能力不足”,本刊分析認為這主要來自于金融危機和經濟反彈所帶來的連鎖反應。金融危機到來時,國外半導體供應商對市場過于悲觀而反應過度,代工訂單總量驟然大減。然而近期市場回暖,為了搶占市場份額,訂單猛增使代工廠產能趨于飽和而無暇顧及規模較小的本土IC公司。而“沒有合適的工藝”,主要來自于模擬和電源 IC對特殊工藝的需求。總言之,歸結于規模小,多數本土公司在與代工廠議價和要求得到技術支持方面仍處于下風。

盡管Cadence的業務在歐美市場受到較大沖擊,但在中國市場仍然是最受歡迎的EDA供應商。Mentor Graphics則憑借諸如驗證、DFT等優勢產品繼續在中國市場快速增長。在IP業務方面,Synopsys領先于其他兩大EDA巨頭,其中 Mentor Graphics已經放棄在IP業務上增加投入;Cadence在IP領域上則動作頻頻,近期完成了Denali的收購以及與ARM在IP可互用方面展開合作,而代工廠中芯國際也表示將在IP業務上發力,值得期待。

模擬ASIC、電源管理IC、數據轉換IC和驅動器/控制器IC是回復者公司最主要從事的模擬和混合信號IC設計。而在數字IC設計方面,則集中于數字 ASIC和SoC。超過90%的公司表示進行自有品牌IC的銷售。然而,產品生命周期、質量和渠道不穩定等因素使直銷和分銷結合的銷售模式成為當前本土 IC的大勢所趨。另外,在綜合的設計挑戰里面,降低設計成本和縮短設計周期是眾多回復者公司的設計訴求。設計的具體技術挑戰則表現為EMI/ESD、電源管理和IP驗證等多個方面。

約6成的本土IC目標應用集中于中低端的消費電子,包括手機、PMP、STB、上網本和電子書這些現如今最熱門的應用領域。目標應用為計算機及其外圍、網絡設備的本土IC分別有18%和10%,變化相對穩定。而飆升最快且值得關注的是汽車電子應用。我們分析的原因是:在內需政策和龐大的汽車市場推動下,汽車電子成為一些本土IC設計公司競相角逐的市場。誠然,本土IC的應用主要還在后裝車用音響以及 PND等領域。盡管合資或本土車廠對國產車用零部件的采購的擴張潛力巨大,但近期寄望本土IC在動力系統控制芯片或車用功率半導體方面打開局面的希望不大。

本土IC設計公司的能力在不斷提升。尤其在全球經濟后衰退期間,將是本土IC設計產業快速發展的蜜月期。單獨地來看,0.13微米和0.18微米工藝的采用率依然很大,但是在90納米以下工藝在不斷增大。盡管45納米及其以下工藝的研發成本高企,但已有少數幾家本土公司的40納米芯片已經流片,以及一些公司也處于40納米IC的研發階段。由于高昂的資金投入會令大多數本土公司望而卻步,因此本刊相信未來幾年65納米節點將會是本土數字IC設計的主力軍。從芯片的規模上來看,100萬-250萬ASIC門的設計項目比較突出。然而,本刊注意到一些有實力雄厚的本土公司,已經開發出幾千萬門規模的芯片,估計未來一兩年很快有超過1億ASIC門的芯片誕生。隨著IC設計能力取得突破,本土公司實力已初露端倪,相信很快將看到越來越多的本土優秀企業在創業板甚至納斯達克上IPO。

SMIC CEO: China foundry vendor back on track

Mark LaPedus

10/8/2010 11:43 PM EDT



After a tumultuous period, Chinese foundry provider Semiconductor Manufacturing International Corp. (SMIC) is back on track, according to the company’s top executive. SANTA CLARA, Calif. – After a tumultuous period, Chinese foundry provider Semiconductor Manufacturing International Corp. (SMIC) is back on track, according to the company’s top executive.



David N.K. Wang, the new executive director, president and chief executive of SMIC (Shanghai), said the foundry vendor has moved to restore customer confidence, put more emphasis on becoming profitable and narrowed its technology focus.  



SMIC appears to be focusing on a core group of major foundry markets--logic, analog, mixed-signal, among others—as opposed to being all things to all people.



''We’ve put a higher priority on service,’’ Wang told EE Times during an interview at the company’s technology event here on Friday (Oct. 8).  The end goal for SMIC is to ''be as good’’ or better than the competition, he said.



At the event, China’s largest foundry vendor also rolled out its process roadmap, in which the company is clearly lagging behind its rivals. ''We want to close the (technology) gap with our peers,’’ he said. ‘’We also want to be the preferred second-source foundry for first-tier customers’’ and ''the first choice’’ among chip makers in China.



Time will tell if SMIC can achieve those lofty goals. As before, the company continues to face stiff competition from GlobalFoundries, Samsung, TSMC, UMC and others in the foundry business.  And IC business is slowing, leaving some to believe that the ongoing shakeout in the foundry business will accelerate.



Many believe SMIC will survive. It has the backing of the mighty Chinese government, which won’t let a prized firm like SMIC fail, analysts said.  Last year, TSMC remained the world's largest foundry in terms of sales, followed in order by UMC, Chartered, SMIC and GlobalFoundries, according to IC Insights Inc.



Right now, the foundry business is heating up. ''We readily agree that an arm’s (capital spending) race is continuing in the foundry space thanks to 28-nm spending from TSMC, and capacity adds from Samsung LSI and GlobalFoundries,’’ said C.J. Muse, an analyst with Barclays Capital, in a report. ''But we do expect foundry spending to decline 3 percent to 19 percent in 2011.’’



The two main Chinese foundries – SMIC and Hua Lei – will see ''limited spending into next year,’’ he said. ''Based on our checks, neither company is looking to migrate aggressively to advanced nodes in 2011 (maximum  1 immersion tool for each). As for capacity, SMIC has discussed expansion of their Beijing fab by (about) 6,000 (wafers) from now until 2Q ‘11 – however, most of the tooling will be installed by the end of this year, suggesting more limited spillover into 2011. For modeling purposes, we have assumed flat at a combined $1.1 billion in (capital spending in) 2011 with risk potentially to the downside.’’



In any case, Wang has made strides at SMIC as part of a major turnaround strategy. Wang was named to the top post at SMIC about 11 months ago. He replaced Richard Chang, who resigned to pursue other personal interests.



Under Chang, SMIC’s CEO since its inception, SMIC experienced an endless string of losses and technology delays. The company continued to build fab capacity-sometimes at the expense of profits and even before it had committed customers.



And in the beginning, SMIC wanted to compete in the breakneck technology race against TSMC, UMC and others.  And it wanted to be all things to all people, as SMIC entered into the analog, MEMS, LCD, solar and other foundry fronts.



That strategy proved to be flawed. And worse, SMIC last year lost a bitter patent suit against Taiwan Semiconductor Manufacturing Co. Ltd. TSMC alleged that SMIC had been using its trade secrets and infringing patents. Under the terms of the settlement, SMIC agreed to pay TSMC $200 million plus stocks equivalent to 8 percent holding in SMIC and warrants to purchase a further 2 percent.



To fix the company’s damaged reputation and bottom line, the board last year hired Wang, a long-time semiconductor executive.  Under Wang, SMIC has shaken up the organization, cut jobs, and brought in new and seasoned management.



He has also narrowed the company’s technology focus and shed unwanted capacity.  For example, SMIC reportedly exited the solar foundry business.



SMIC has been managing fabs in Chengdu and Wuhan, China for the respective municipal governments in those Chinese cities. Seen as a major distraction, the company has reportedly exited from its arrangement in Chengdu.  Texas Instruments Inc. has reportedly bought the Chengdu fab. SMIC is looking to exit from its arrangement in Wuhan. Reports have surfaced that Micron Technology Inc. is looking at that fab.



New thinking at SMIC

More importantly, Wang also instilled some new business practices at SMIC: It is looking for sustained profitability. Right now, SMIC also has a better product and customer mix than before, Wang said. And to help matters, SMIC recently received a capital injection from Datang Telecom of China.



Under the previous regime, SMIC was trying to ''get big before it was solid,’’ he said. Now, SMIC ‘’needs to get strong before it gets big.’’



Thanks to a settlement with a rival, SMIC recently posted its first quarterly profit since 2007.  SMIC's sales hit $381.1 million in the second quarter, up 8.4 percent from $351.7 million in the first quarter and up 42.5 percent compared to the like period a year ago. Net income attributable to holders of ordinary shares was $96.0 million in the second quarter, compared to loss of $181.9 million in the first quarter and a loss of $97.4 million a year ago.

  

The profit was driven by a one-time gain of $105.9 million of commitment to grant shares and warrants. The gain came from securities issued to TSMC as part of a settlement in a suit last year.SMIC also doubled its capital spending. 2010 annual capital expenditures are expected to range from $700-to-$750 million.



At present, however, there is a slowdown in the IC market. Going forward, Wang is still bullish despite the slowdown, saying SMIC is seeing good demand. ''I think we’re in a pretty good cycle,’’ he said.



Wang said the company has restored customer confidence after the IP snafu with TSMC.  Several customers that were reluctant to do business with SMIC have switched gears and ''now they are approaching us,’’ he said.



One of the advantages for SMIC is clear: It has a large manufacturing base in the world’s largest consumer market in China. SMIC has fabs in Beijing, Taijin, and Shanghai.



But one of the challenges is that SMIC is lagging in terms of technology.  At present, SMIC is ramping up its leading-edge technology: a 65-nm process.



Wang acknowledged that SMIC is at least five years behind the competition at 65-nm and two-to-three years behind at 45-nm. The goal for the company is to narrow the gap between SMIC and its rivals.  



To do so, SMIC will require massive capital and technical prowess to narrow the gap. It has licensed some technology from IBM Corp., but the challenge is to put the process into mass production.



Recently, SMIC has moved its low-leakage 65-nm process technology into volume production at its 300-mm facility in Beijing. It is also working on the transition to 55-nm technology, which is due in pilot production by the third quarter of 2011.

SMIC is also working on a 55-nm general purpose process, which is due in pilot production in the fourth quarter of 2011.  



SMIC is also working on a 45-/40-nm low leakage process, which is due in pilot production in the fourth quarter of 2011. SMIC is also working on a 45-/40-nm general purpose process, which is due in pilot production in the second quarter of 2012.



SMIC licensed the 45-nm process from IBM in 2007. SMIC is also devising a 32-nm process, which was also licensed from IBM.SMIC is also working on analog and mixed-signal. It is devising a bipolar-CMOS-DMOS (BCD) process.
