Pamene mliri wa COVID-19 ukupitilira ndipo kufunikira kwa tchipisi kukukulirakulira m'magawo kuyambira zida zoyankhulirana kupita kumagetsi ogula mpaka pamagalimoto, kuchepa kwa tchipisi kukukulirakulira.
Chip ndi gawo lofunikira kwambiri pamakampani azidziwitso, komanso makampani ofunikira omwe amakhudza gawo lonse laukadaulo wapamwamba kwambiri.
Kupanga chip imodzi ndi njira yovuta yomwe imaphatikizapo masitepe zikwi zambiri, ndipo gawo lililonse la ndondomekoyi limakhala ndi zovuta, kuphatikizapo kutentha kwakukulu, kukhudzana ndi mankhwala osokoneza bongo, komanso zofunikira zaukhondo kwambiri.Pulasitiki amagwira ntchito yofunika kwambiri popanga semiconductor, pulasitiki antistatic, PP, ABS, PC, PPS, fluorine, PEEK ndi mapulasitiki ena amagwiritsidwa ntchito kwambiri popanga semiconductor.Lero tiwona zina mwazomwe PEEK ili nazo mu semiconductors.
Chemical mechanical grinding (CMP) ndi gawo lofunikira la semiconductor kupanga njira, yomwe imafuna kuwongolera kokhazikika, kuwongolera kokhazikika kwa mawonekedwe apamwamba komanso pamwamba pamtundu wapamwamba.Kapangidwe ka miniaturization imayikanso patsogolo zofunikira pakugwirira ntchito, kotero kuti zofunikira za CMP fixed ring zikuchulukirachulukira.
Mphete ya CMP imagwiritsidwa ntchito kugwirizira chophatikizirapo panthawi yopera.Zinthu zomwe zasankhidwa ziyenera kupewa kukwapula ndi kuipitsidwa pamtunda.Nthawi zambiri amapangidwa ndi PPS wamba.
PEEK imakhala ndi kukhazikika kwapamwamba kwambiri, kusavuta kukonza, makina abwino amakina, kukana kwamankhwala, komanso kukana kuvala bwino.Poyerekeza ndi mphete ya PPS, mphete yokhazikika ya CMP yopangidwa ndi PEEK ili ndi kukana kokulirapo komanso moyo wautumiki wapawiri, motero imachepetsa nthawi yopumira ndikuwongolera zokolola zawafa.
Kupanga ma wafer ndi njira yovuta komanso yovuta yomwe imafuna kugwiritsa ntchito magalimoto kuti ateteze, kunyamula, ndi kusunga zowotcha, monga mabokosi otsegulira otsegulira (FOUPs) ndi mabasiketi owonda.Zonyamulira za semiconductor zimagawidwa m'njira zambiri zopatsirana ndi asidi ndi njira zoyambira.Kusintha kwa kutentha panthawi ya kutentha ndi kuzizira ndi njira zochizira mankhwala kungayambitse kusintha kwa kukula kwa zonyamulira zopyapyala, zomwe zimapangitsa kuti chip scratch kapena kusweka.
PEEK itha kugwiritsidwa ntchito kupanga magalimoto kuti azitengera njira zopatsirana.Anti-static PEEK (PEEK ESD) imagwiritsidwa ntchito kwambiri.PEEK ESD ili ndi zinthu zambiri zabwino kwambiri, kuphatikiza kukana kuvala, kukana mankhwala, kukhazikika kwa mawonekedwe, katundu wa antistatic ndi ma degas otsika, omwe amathandizira kupewa kuipitsidwa ndi tinthu tating'ono ndikuwongolera kudalirika kwa kagwiridwe ka mkate, kusunga ndi kusamutsa.Limbikitsani kukhazikika kwa bokosi lakutsogolo lotseguka lawafer (FOUP) ndi dengu lamaluwa.
Bokosi la masks onse
Njira ya lithography yomwe imagwiritsidwa ntchito popanga chigoba chojambula iyenera kukhala yoyera, kutsatira kuphimba kowala kapena zokopa zilizonse pakuwonongeka kwamtundu, chifukwa chake, chigoba, kaya pakupanga, kukonza, kutumiza, kutumiza, kusungirako, zonse ziyenera kupewa kuipitsidwa ndi chigoba komanso kukhudzidwa kwa tinthu tating'ono chifukwa cha kugundana ndi ukhondo wa chigoba cha mkangano.Pomwe makampani opanga ma semiconductor ayamba kuyambitsa ukadaulo wowonjezera wa kuwala kwa ultraviolet (EUV), kufunikira kosunga masks a EUV opanda chilema ndikwambiri kuposa kale.
Kutulutsa kwa PEEK ESD ndi kuuma kwakukulu, tinthu tating'onoting'ono, ukhondo wambiri, antistatic, kukana kwa dzimbiri kwa mankhwala, kukana kuvala, kukana kwa hydrolysis, mphamvu yabwino ya dielectric komanso kukana kwambiri kwa magwiridwe antchito a radiation, popanga, kufalitsa ndi kukonza chigoba, kumatha kupanga chigoba chosungidwa mu degassing otsika komanso kuipitsidwa kwa ma ionic kwa chilengedwe.
Chip test
PEEK imakhala ndi kukana kutentha kwambiri, kukhazikika kwa mawonekedwe, kutsika kwa gasi, kukhetsa kwa tinthu tating'ono, kukana kwa dzimbiri kwa mankhwala, komanso kukonza makina osavuta, ndipo chitha kugwiritsidwa ntchito poyesa chip, kuphatikiza mbale zotentha za matrix, mipata yoyesera, matabwa osinthika, akasinja oyesera. , ndi zolumikizira.
Kuphatikiza apo, pakuwonjezeka kwa kuzindikira kwachilengedwe pakusunga mphamvu, kuchepetsa umuna ndi kuchepetsa kuipitsidwa kwa pulasitiki, makampani opanga ma semiconductor amalimbikitsa kupanga zobiriwira, makamaka kufunikira kwa msika wa chip ndikolimba, ndipo kupanga chip kumafunikira mabokosi ophatikizika ndi zigawo zina zofunika kwambiri, chilengedwe. kukhudzika sikungachedwe.
Chifukwa chake, makampani opanga ma semiconductor amatsuka ndikubwezeretsanso mabokosi ophatikizika kuti achepetse kuwononga zinthu.
PEEK imawonongeka pang'ono ikatha kutenthedwa mobwerezabwereza ndipo imatha kubwezeretsedwanso 100%.
