Uyini Umshini Wokunamathisela Chip?

A umshini wokugcwalisa i-chip iyithuluzi elikhethekile elisetshenziswa ekwenziweni kwe-semiconductor ukususa izinto ngokukhetha kumawafa e-silicon. Le nqubo, eyaziwa ngokuthi i-etching, idala amaphethini esekethe ayinkimbinkimbi abalulekile kuma-electronics wesimanje. Ukunemba kwe-a umshini wokugcwalisa i-chip iqinisekisa ukuthi izingxenye zihlangabezana ncamashi nokucaciswa komklamo, okuyenza ibaluleke kakhulu ekukhiqizeni amadivaysi afana nama-smartphone namakhompyutha. Ngokungafani nezindlela zemishini zendabuko, imishini ethuthukisiwe isebenzisa i-plasma noma ukusabela kwamakhemikhali ngokunemba kwe-nanoscale. Ngokwesibonelo, izinkampani ezifana Izinto zokusebenza ezifakiwe futhi Ucwaningo lweLam lawula le nkambu, enikeza amasistimu ahlanganisa okuzenzakalelayo kokuphuma okuphakeme. Funda kabanzi mayelana nezinqubo ze-semiconductor ku Semiconductor Industry Association.

Umlando Wokuthuthuka Wemishini Yokunamathisela Chip

Ukuvela kwe imishini yokukhipha ama-chip ikhombisa intuthuko kubuchwepheshe be-semiconductor. Ngawo-1960s, i-etching emanzi yayibusa, kusetshenziswa amakhemikhali awuketshezi ukuncibilikisa i-silicon engavikelekile. Kodwa-ke, ukukhuphuka kwamasekethe adidiyelwe kudinga ukulawulwa okucolisekile, okuholela kumasu omile wokuhlanganisa njenge-reactive ion etching (RIE) ngeminyaka yawo-1980. Ngawo-2000s, amasistimu asekelwe ku-plasma aqala ukujwayelekile, avumela ukunemba kwe-sub-10nm. Namuhla, izinto ezintsha ezifana ne-atomic layer etching (ALE) ziqhubezela phambili imingcele. Lokhu kuqhubekela phambili kugcizelela ukuthi kanjani umshini wokugcwalisa i-chip amakhono akhe uMthetho kaMoore, ovumela ama-transistors ukuthi anciphe ngenkathi ukusebenza kukhuphuka.

Izinyathelo Eziyinhloko

• Ama-1960: Ukwethulwa kwe-etching emanzi yama-ICs angaphambi kwesikhathi.
• Ama-1980: Shift ukuze omise etching ukuze uthole ukunemba okuphezulu.
• Ama-2000: I-Plasma etching ifinyelela ukunemba kwesikali se-nanometer.
• Ama-2020: Ukufakwa kwesendlalelo se-athomu (ALE) kunika amandla ukwakheka kwe-chip ye-3D.

Izici Zomshini Wokunamathisela Chip

Modern imishini yokukhipha ama-chip zichazwa izici ezintathu ezibalulekile: ukunemba, ukukala, kanye nokuhlukahluka. Ukunemba kuqinisekisa ukulahleka okuncane, okubalulekile kuma-chips anezendlalelo eziningi. I-scalability ivumela ukuzivumelanisa nosayizi wama-wafer afika ku-450mm, ukuhlangabezana nezidingo zokukhiqiza ngobuningi. I-Versatility ivela kumiklamo ye-modular esekela kokubili amakhemikhali kanye ne-plasma etching. Ngokwesibonelo, I-Tokyo ElectronAmasistimu anikezela ngezingxube zegesi ezilungisekayo ukuphatha izinto ezahlukahlukene njenge-silicon, ama-oxide, nezinsimbi. Lezi zici zenza imishini yokukhipha ama-chip kubalulekile ekwakheni ama-node athuthukile ngezinqubo ezingu-5nm nangaphansi.

Amapharamitha weMishini ye-Chip Etching

ukukhetha a umshini wokugcwalisa i-chip idinga ukuhlola amapharamitha njengezinga le-etch, ukufana, nokukhetha. Isilinganiso se-Etch sinquma ukuphuma, kuyilapho ukufana kuqinisekisa imiphumela engaguquki kuwo wonke ama-wafers. ukukhetha—ikhono lokukhomba izinto ezithile—kunciphisa umonakalo ezingqimbeni ezingaphansi. Amasistimu athuthukile aphinde aqaphe amapharamitha esikhathi sangempela afana nokuminyana kwe-plasma namandla e-ion. Ngokwesibonelo, ASMLAmathuluzi asebenzisa izinzwa ukulungisa izimo ngendlela eguquguqukayo, ethuthukisa ukusebenza. Lawa mamethrikhi athinta ngokuqondile isivuno kanye nokusebenza kahle kwezindleko, okuwenza abaluleke kakhulu emaqenjini okuthenga.

Izindima Zemishini Yokunamathisela I-Chip Ekwenziweni Kwe-Semiconductor

Ekwenziweni kwe-semiconductor, imishini yokukhipha ama-chip sebenza izindima ezimbili eziyinhloko: ukudluliswa kwephethini nokususwa kwezinto. Ngesikhathi se-photolithography, amaphethini aqoshiwe achaza amasango e-transistor kanye nezixhumanisi. Ngemuva kokufakwa, ukunamathisela kususa izinto ezingaphezulu ukuze kuhlukanise izingxenye. Lo msebenzi ombaxambili uqinisekisa ukuthi ama-chips ahlangabezana nokucaciswa kukagesi nokushisayo. Njengoba amadivayisi ancipha, indima ye imishini yokukhipha ama-chip inweba ukuze ifake ukwakheka kwe-3D kwamaseli enkumbulo afana ne-NAND flash. Intuthuko enjalo igcizelela ukungabuyiseleki kwabo okuthile ekwakhiweni okuphambili.

Izicelo ze-Chip Etching Machines

Imishini yokufaka ama-chip zibalulekile kuzo zonke izimboni:

• I-Consumer Electronics: Ikhiqiza ama-CPU, ama-GPU, nama-memory chips wamadivayisi.
• Izithuthi: Ukwakha izinzwa nama-IC okuphatha amandla ama-EV.
• Ukunakekela impilo: Ukudala ama-biochips okuxilongwa kwezokwelapha.

Izinhlelo zokusebenza ezisafufusa zihlanganisa i-quantum computing kanye ne-electronics flexible, lapho i-etching inika amandla i-architectures yenoveli. Ngokwesibonelo, Intel isebenzisa i-etching ethuthukisiwe ukwakha ama-transistors astakiwe ama-accelerator e-AI.

Abakhiqizi beMishini ye-Chip Etching

Ehola umshini wokugcwalisa i-chip abakhiqizi bahlanganisa:

• Izinto Ezisetshenziswayo: Kwaziwa ngamasistimu e-plasma aphezulu.
• Ucwaningo lwe-Lam: Isebenza ngokukhethekile kuzixazululo ze-dielectric ne-metal etching.
• I-Tokyo Electron (TEL): Inikeza amasistimu we-hybrid wezinto ezahlukahlukene.

Lezi zinkampani zitshala imali eningi ku-R&D ukuze kubhekwane nezinselele ezifana nephutha lokubekwa onqenqemeni kanye nobulukhuni bomugqa, ukuqinisekisa ukuthi amathuluzi azo ahlangabezana nezidingo zesizukulwane esilandelayo.

Isiphetho

Kusukela ekunikeni amandla amasekhethi e-nanoscale kuya ekunikezeni amandla ukusungulwa kobuchwepheshe bomhlaba wonke, imishini yokukhipha ama-chip ihlale ingumgogodla wokukhiqiza ama-semiconductor. Amathimba okuthengwa kwempahla nobunjiniyela kufanele abeke phambili amapharamitha, izinhlelo zokusebenza, nolwazi lwabathengisi lapho ekhetha lezi zinhlelo. Njengoba imboni ithuthukela ku-2nm nodes nangale kwalokho, indima ye imishini yokukhipha ama-chip izokhula ibucayi kakhulu.
