Mu kusintha kwa digito masiku ano, kukula kwakukulu kwa kutumiza deta kukuyendetsedwa ndi kuyanjana kwa mafoni a m'manja pafupipafupi, zochitika za AR/VR zomwe zimakhudzidwa kwambiri, komanso ntchito zambiri zamakompyuta mu makompyuta ogwira ntchito bwino. Ma phukusi achikhalidwe a 2D—okhala ndi njira zazitali zolumikizirana komanso kutayika kwakukulu kwa kutumiza—sangathenso kudutsa mipata yogwirira ntchito.
Zotsatira zake, kuyika ma chip stacking ndi ma 3D packaging kwakhala njira yoyendetsera makampani. Kuti athe kulumikizana bwino kwa 3D, ukadaulo wa Through Glass Via (TGV) wadziwika bwino ndi zabwino zake zapadera, kuchoka pa R&D reserves kupita ku mafakitale. TGV tsopano ikukhala chida chofunikira kwambiri pazida zamagetsi zam'badwo wotsatira.
1. Ukadaulo wa TGV: "Mlatho" wa Kulumikizana kwa 3D
1.1 Lingaliro Lofunika: Kodi TGV ndi chiyani kwenikweni?
Chofunika kwambiri cha TGV ndi kupanga ma microvia olunjika kudzera mu galasi. Ma vias awa amagwira ntchito ngati milatho yamagetsi, yolumikiza mwachindunji ma chips kapena zigawo zina, zomwe zimathandiza kutumiza chizindikiro ndi mphamvu. Poyerekeza ndi "ma waya ozungulira" achikhalidwe, kulumikizana kolunjika kumafupikitsa kwambiri njira zotumizira mauthenga ndikuthandizira kuchepetsa mphamvu ya chipangizocho komanso kuphatikiza kwakukulu.
1.2 Chifukwa Chake Magalasi Okhala Ndi Magalasi Ndiwo Chonyamulira Chachilengedwe cha TGV
TGV imaposa TSV (Kudzera mu Silicon Via) chifukwa cha zabwino zitatu zazikulu za galasi:
Chosasinthika cha dielectric chochepa - kuteteza zizindikiro zama frequency apamwamba: Galasi mwachibadwa limakhala ndi chosintha chochepa cha dielectric, kuchepetsa kutayika kwa dielectric panthawi yotumizira ndikusunga umphumphu wa chizindikiro mu ntchito zama frequency apamwamba monga 5G ndi HPC.
Kugwirizana kwa kutentha ndi silicon - kukulitsa kudalirika: Galasi limagwirizana kwambiri ndi kuchuluka kwa kutentha kwa silicon, kuchepetsa kupsinjika kwa thermo-mechanical ndi kulephera panthawi ya kutentha, motero kumawonjezera nthawi ya chipangizocho.
Kuwonekera bwino kwa kuwala - komwe kumathandizira kuphatikiza kwa optoelectronic: Mosiyana ndi silicon yosawoneka bwino, kuwonekera bwino kwa galasi kumathandizira kugwiritsa ntchito ma electro-optical hybrid. Mwachitsanzo, mu ma module a silicon photonics, galasi limalola kulumikizana kwamagetsi ndi kutumiza chizindikiro cha optical; mu ma microdisplay a AR/VR, kuwonekera bwino kumachepetsa kutsekeka kwa kuwala ndikuwongolera kuwala ndi kuwonekera bwino.
1.3 Kuchokera ku TSV kupita ku TGV: Kusintha Kwachilengedwe
TGV isanayambe, TSV inali ukadaulo wodziwika bwino wa 3D interconnect. Komabe, TSV ikukumana ndi mavuto ambiri pamene kuchuluka kwa ma integration kukukwera:
Mtengo wokwera: Kuyenda kwa njira zovuta—kudula, kutchinjiriza, kusungunula zitsulo—kumapangitsa TSV kukhala yosayenerera kupanga zinthu zazikulu.
Zovuta Zodalirika: Kusalingana kwa kutentha pakati pa silicon ndi zinthu zina nthawi zambiri kumabweretsa kusweka kapena kulephera kwa malo olumikizirana.
Kuchuluka kwa ntchito: Kusawoneka bwino kwa Silicon sikuchotsa TSV ku mapulogalamu a optoelectronic omwe amafuna kuwonekera poyera.
TGV imathetsa mavutowa bwino, zomwe zimapangitsa kuti ikhale njira yabwino kwambiri yolumikizirana ya m'badwo wotsatira.
2. Kudzera mu Kuphimba: Chothandizira Chachikulu Chomwe Chimapangitsa TGV Kugwira Ntchito
2.1 Chidziwitso Chofunika: Popanda Kuphimba, TGV ndi "Chubu Chopanda Kanthu"
Magalasi opangidwa ndi magalasi ndi oteteza kutentha ndipo sangayendetse magetsi. Kuti magetsi azitha kulumikizidwa, gawo lowongolera magetsi (nthawi zambiri filimu yachitsulo) liyenera kuyikidwa m'mbali mwa makoma a magalasi. Gawoli limagwira ntchito ngati msewu waukulu wa chizindikiro—kuzindikira liwiro, kutayika, ndi kukhazikika. Zophimba zosafanana kapena zolakwika zimayambitsa kukana kwakukulu, kuchepa kwa chizindikiro, kapena ngakhale ma circuits otseguka, zomwe zimapangitsa kuti kudzera mu metallization ikhale njira yothandiza kwambiri ya ukadaulo wa TGV.
2.2 Mavuto: Mfundo Ziwiri Zofunika Kwambiri Zokhudza Ululu
Kufunika kwa Chiŵerengero Chachikulu cha Mawonekedwe
Ma diameter a TGV tsopano ali mu micrometer range (mpaka ~30 μm) ndipo kuya kwake kumapitirira 10:1 aspect ratios. Njira zachikhalidwe zoyika zinthu zimavutika kupeza pansi ndi mafilimu ofanana a m'mbali, nthawi zambiri zimasiya "malo akufa" osaphimbidwa omwe amawononga magwiridwe antchito a interconnect.
Kulamulira Kwabwino - Wakupha Wobisika
Makona ndi zitseko zozungulira m'mbali zimakhala ndi malo obisika kapena thovu. Zolakwika izi zimayambitsa kukana kwa malo kapena ma circuits otseguka, zomwe zimaswa mwachindunji kulumikizana pakati pa tchipisi ndi zida. Chifukwa chake, kuletsa zolakwika ndiye vuto lalikulu la utoto wa TGV.
3. Njira Zinayi Zophikira: Mphamvu ndi Zofooka
Kutulutsa Nthunzi Yathupi (PVD): Yokhwima Koma Yochepa
Njira monga kupopera ndi kutulutsa madzi zimapangitsa kuti mafilimu akhale oyera kwambiri komanso ogwirizana kwambiri. Komabe, chifukwa cha mawonekedwe ake a "mzere wowonekera", PVD imavutika ndi ma vias okhala ndi chiŵerengero chapamwamba ndipo ndi yoyenera kwambiri ma vias okhala ndi chiŵerengero cha ~5:1.
Kutulutsa nthunzi ya mankhwala (CVD): Kuchuluka kwa maonekedwe abwino koma kokwera mtengo
CVD imagwiritsa ntchito mpweya woyambira womwe umafalikira kudzera m'mbali mwa khoma, zomwe zimapangitsa kuti zikhale zofanana ngakhale m'zipinda zokhala ndi chiŵerengero chapamwamba. Komabe, kutentha kwambiri ndi kupanikizika kumatha kuwononga magalasi, ndipo mtengo wa zida ndi wokwera, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito kwambiri.
Kuyika kwa Ma Electrochemical (ECD): Kupanga Zinthu Mosawononga Ndalama
Ma ECD amaika mafilimu oyendetsera magetsi pochepetsa ma ayoni achitsulo kudzera m'mbali mwa makoma. Amapereka mtengo wotsika komanso mphamvu zambiri, zomwe ndi zabwino kwambiri popanga voliyumu. Komabe, kuwongolera bwino kuchuluka kwa ma electrolyte ndi kuchuluka kwa magetsi ndikofunikira—kupotoka kumabweretsa mafilimu okhala ndi mabowo kapena kuipitsidwa. Nthawi zambiri amagwiritsidwa ntchito pa ma vias a 5–50 μm m'mimba mwake.
Kuyika kwa Atomic Layer (ALD): Yankho Lolondola
ALD imakwaniritsa kulamulira kwa makulidwe a atomiki komanso kusinthasintha kwabwino kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kwambiri pa ma aspect ratio via apamwamba kwambiri. Imathetsa vuto la coverage koma imakhala ndi kuchepa kwa ma deposition rates komanso mtengo wokwera. Chifukwa chake, ALD imasungidwa makamaka kuti igwiritsidwe ntchito poyendetsa ndege komanso masensa odalirika kwambiri.
4. Kufunika kwa TGV Coating: Kuyendetsa Magwiridwe Abwino a 3D Interconnection
Kupita Patsogolo kwa Liwiro - Kulumikizana Molunjika Kwa Liwiro Lalikulu
Mu ma phukusi a 2D, zizindikiro ziyenera kuyenda mtunda wautali, zomwe zimawonjezera kutayika. Ndi TGV metallization, ma chip-to-board ndi chip-to-system interconnects amakhala afupiafupi, olunjika, komanso otsika kutayika. Mu ma seva a HPC, ma vias okhala ndi TGV amalola liwiro la kulumikizana kwa CPU-to-memory/GPU kukhala labwino ndi kupitirira 30%, kuchepetsa kuchedwa ndikuwonjezera magwiridwe antchito a makina.
Kugwiritsa Ntchito Mphamvu Moyenera - Kuchedwa Kochepa ndi Kugwiritsa Ntchito Mphamvu Mochepa
Njira zazifupi zolumikizirana zimachepetsa kuchedwa, pomwe zokutira zosalimba zimachepetsa kutentha kwa Joule. Mwachitsanzo, kulongedza kwa ma chip a foni yam'manja pogwiritsa ntchito TGV kumatha kuchepetsa kugwiritsa ntchito mphamvu ndi 15–20%, kukulitsa moyo wa batri ndikuwonjezera luso la ogwiritsa ntchito.
5. Zhenhua Vacuum: Mayankho Opangira TGV Otsogola
Ubwino wa Zida
Kukonza Kwambiri
Ukadaulo wopaka mabowo akuya umathandiza kuti mbewu ziziikidwa mofanana ngakhale m'mabowo ang'onoang'ono ngati 30 μm okhala ndi ma aspect ratios opitilira 10:1—kuthetsa vuto limodzi lovuta kwambiri m'makampani.
Kusamalira Substrate Kosinthika
Imathandizira mitundu yosiyanasiyana ya magalasi, kuphatikizapo 600 × 600 mm / 510 × 515 mm, yokhala ndi kukula kokulirapo.
Kusinthasintha kwa Njira - Kugwirizana kwa Zinthu Zambiri
Imathandizira makanema oyendetsera magetsi komanso ogwira ntchito monga Cu, Ti, W, Ni, ndi Pt, kukwaniritsa zofunikira zosiyanasiyana zogwiritsira ntchito kuti magetsi aziyenda bwino komanso kuti asagwe ndi dzimbiri.
Magwiridwe Okhazikika ndi Kusamalira Kosavuta
Yokhala ndi njira zanzeru zowongolera njira zowunikira nthawi yeniyeni makulidwe a filimu, komanso kapangidwe kake kosavuta kukonza komanso kuchepetsa nthawi yogwira ntchito.
Chiwerengero cha Ntchito
Imagwiritsidwa ntchito pa ma CD apamwamba a TGV/TSV/TMV, zomwe zimathandiza kuti mbeu zisungidwe m'magawo a deep vias okhala ndi aspect ratios ya 10:1.
—Nkhaniyi yafalitsidwa ndi zida zophikira zotsukira wopanga Zhenhua Vacuum
