Kev lag luam saw
Kev lag luam semiconductor, yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv hluav taws xob hauv kev lag luam, yog tias muab faib raws li cov khoom sib txawv, lawv feem ntau yog cais raws li: cov khoom siv sib cais, kev sib xyaw ua ke, lwm yam khoom siv thiab lwm yam. Ntawm lawv, cov khoom siv sib cais tuaj yeem muab faib ntxiv rau hauv diodes, transistors, thyristors, transistors, thiab lwm yam, thiab kev sib xyaw ua ke tuaj yeem muab faib ntxiv rau hauv analogue circuits, microprocessors, logic integrated circuits, nco thiab lwm yam.
Cov khoom tseem ceeb ntawm kev lag luam semiconductor
Semiconductors yog lub hauv paus ntawm ntau cov khoom ua tiav, uas yog siv rau hauv cov khoom siv hluav taws xob, kev sib txuas lus, tsheb, kev lag luam / kev kho mob, khoos phis tawj, tub rog / tsoom fwv, thiab lwm qhov chaw tseem ceeb. Raws li Semi cov ntaub ntawv nthuav tawm, semiconductors feem ntau yog tsim los ntawm plaub ntu: kev sib xyaw ua ke (kwv yees li 81%), cov khoom siv hluav taws xob optoelectronic (li 10%), cov khoom siv sib cais (li 6%), thiab cov sensors (kwv yees 3%). Txij li cov kev sib xyaw ua ke suav nrog feem pua ntawm tag nrho, kev lag luam feem ntau sib npaug ntawm cov khoom siv hluav taws xob nrog kev sib xyaw ua ke. Raws li cov khoom sib txawv, kev sib xyaw ua ke tau muab faib ua plaub pawg tseem ceeb: cov khoom siv logic (kwv yees 27%), nco (kwv yees 23%), microprocessors (li 18%), thiab cov khoom siv analogue (kwv yees 13%).
Raws li kev faib tawm ntawm kev lag luam saw, semiconductor kev lag luam saw tau muab faib rau hauv kev txhawb nqa kev lag luam kev lag luam, midstream core kev lag luam saw, thiab downstream xav tau kev lag luam saw. Kev lag luam muab cov ntaub ntawv, khoom siv, thiab kev tsim vaj tsev huv si raug cais raws li kev txhawb nqa kev lag luam semiconductor; tsim, tsim, thiab ntim thiab kuaj cov khoom semiconductor raug cais raws li cov kev lag luam tseem ceeb; thiab cov terminals xws li cov neeg siv khoom siv hluav taws xob, tsheb, kev lag luam / kev kho mob, kev sib txuas lus, khoos phis tawj, thiab tub rog / tsoom fwv raug cais raws li cov kev xav tau ntawm kev lag luam.
Kev Lag Luam Loj Loj
Kev lag luam thoob ntiaj teb semiconductor tau tsim los rau hauv kev lag luam loj loj, raws li cov ntaub ntawv txhim khu kev qha, qhov loj ntawm lub ntiaj teb semiconductor kev lag luam hauv 1994 tau tshaj 100 billion US dollars, tshaj 200 billion US dollars nyob rau hauv 2000, ze li ntawm 300 billion US dollars nyob rau hauv 2010, nyob rau hauv 2015. siab li 336.3 billion US dollars. Ntawm lawv, xyoo 1976-2000 kev loj hlob ntawm qhov sib txuas tau mus txog 17%, tom qab 2000, qhov kev loj hlob qeeb pib qeeb, 2001-2008 kev loj hlob ntawm 9%. Nyob rau hauv xyoo tas los no, kev lag luam semiconductor tau maj mam nce mus rau lub sijhawm ruaj khov thiab kev loj hlob, thiab xav tias yuav loj hlob ntawm tus nqi sib xyaw ntawm 2.37% hauv 2010-2017.
Kev loj hlob zeem muag
Raws li tsab ntawv ceeb toom xa tawm tshiab tshaj tawm los ntawm SEMI, tus nqi xa khoom ntawm North American semiconductor cov khoom lag luam nyob rau lub Tsib Hlis 2017 yog US $ 2.27 billion. Qhov no sawv cev nce mus txog 6.4% YoY los ntawm lub Plaub Hlis $ 2.14 billion, thiab nce ntawm $ 1.6 billion, lossis 41.9% YoY, los ntawm tib lub sijhawm xyoo tas los. Los ntawm cov ntaub ntawv, tus nqi xa khoom lub Tsib Hlis tsis yog plaub lub hlis sib law liag, tab sis kuj raug ntaus txij li lub Peb Hlis 2001, cov ntaub ntawv sau tseg.
Cov ntaub ntawv siab txij li lub Peb Hlis 2001. Cov khoom siv semiconductor yog kev tsim kho cov kab ntau lawm semiconductor thiab kev lag luam boom degree pioneer, feem ntau, cov khoom lag luam xa khoom loj hlob feem ntau kwv yees kev lag luam thiab boom upward, peb ntseeg hais tias nyob rau hauv Tuam Tshoj lub semiconductor ntau lawm kab kom ceev raws li ceev ceev. kev lag luam xav tau tsav, kev lag luam thoob ntiaj teb semiconductor xav tias yuav nkag mus rau lub sijhawm tshiab nce ntxiv.
Kev lag luam nplai
Nyob rau theem no, kev lag luam thoob ntiaj teb semiconductor tau tsim los rau hauv kev lag luam loj loj, kev lag luam maj mam loj hlob, nrhiav cov ntsiab lus tshiab kev lag luam hauv ntiaj teb kev lag luam semiconductor tau dhau los ua qhov teeb meem tseem ceeb. Peb ntseeg hais tias txoj kev loj hlob sai ntawm Tuam Tshoj txoj kev lag luam semiconductor xav tias yuav dhau los ua lub zog tshiab rau kev lag luam semiconductor kom ua tiav kev loj hlob hla mus.
2010-2017 ntiaj teb no semiconductor kev lag luam loj ($ billion)
Tuam Tshoj txoj kev lag luam semiconductor tswj hwm kev vam meej, thiab kev lag luam semiconductor hauv tsev yuav tsum ncav cuag 1,686 billion yuan hauv 2017, nrog kev loj hlob ntawm 10.32% los ntawm 2010-2017, ntau dua li lub ntiaj teb semiconductor kev lag luam qhov nruab nrab kev loj hlob ntawm 2.37. %, uas tau dhau los ua ib qho tseem ceeb tsav tsheb rau lub ntiaj teb semiconductor kev ua lag luam.Nyob rau hauv 2001-2016, lub domestic IC lag luam loj hlob los ntawm 126 billion yuan mus txog 1,200 billion yuan, accounting rau ze li ntawm 60% ntawm lub ntiaj teb no kev ua lag luam qhia. Kev lag luam muag tau nthuav dav ntau dua 23 zaug, los ntawm 18.8 billion yuan mus rau 433.6 billion yuan.Nyob rau xyoo 2001-2016, Tuam Tshoj txoj kev lag luam IC thiab kev lag luam CAGR yog 38.4% thiab 15.1% raws li.Lub sijhawm xyoo 2001-2016 Tuam Tshoj tus IC kev lag luam thiab kev ntim khoom, kev tsim khoom thiab ntim khoom. hauv tes nrog CAGR ntawm 36.9%, 28.2%, thiab 16.4% feem. Ntawm lawv, qhov kev faib ua feem ntawm kev tsim kev lag luam thiab kev tsim khoom lag luam tau nce ntxiv, txhawb kev ua kom zoo ntawm IC kev lag luam qauv.
