Amageji e-Alumina Ceramic ekukhiqizweni kwe-Semiconductor: Iminyaka eyi-10 Yokuzinza Okungalingani Nokunemba

Embonini ye-semiconductor, lapho i-micron eyodwa ingaba umehluko phakathi kweqembu elikhiqiza kakhulu kanye nokwehluleka okubizayo, ukukhetha izinto ze-metrology kubalulekile. Njengoba ukuhlolwa kwe-lithography kanye ne-wafer kucindezela imingcele yefiziksi, insimbi yendabuko kanye ne-granite yezinga eliphezulu kufinyelela imikhawulo yayo.

I-Alumina Ceramic (Al2O3) ivele njengesixazululo esiqondile sabakhiqizi bemishini ye-semiconductor. Njengoba isikhathi sokugcina sinembile esingadlula izinto zendabuko ngeminyaka engaphezu kwe-10, izinto zobumba azisaseyona into yokunethezeka—ziyisidingo sesakhiwo.

Kungani i-Alumina Ceramic isetshenziswa kuma-semiconductors?

Ngaphambi kokungena ezicelweni, kubalulekile ukuqonda iphrofayili ehlukile "yezingozi ezintathu" zale nto:

• Ukuzinza Kokushisa: I-coefficient ephansi yokwanda kokushisa (≈7 × 10^{-6}/K) iqinisekisa ukuthi izilinganiso zihlala zihambisana naphezu kokushisa okukhiqizwa imishini yesivinini esikhulu.

• Okungeyona I-Magnetic Futhi Okungeyona I-Conductive: Kubalulekile ezindaweni zokuhlanza kanye ne-lithography ye-electron-beam ebucayi lapho ukuphazamiseka kwe-magnetic kungaphambukisa khona imisebe.

• Akukho Kugqwala: Ngokungafani nensimbi, izinto zobumba azinamakhemikhali, okwenza zihambisane nezinqubo zokuhlanza igumbi lokuhlanza kanye nezindawo zegesi ezigqwalisayo.

Izicelo Ezi-5 Eziyinhloko Emishinini Ye-Semiconductor

1. Izigaba Zomshini We-Lithography

I-photolithography yesimanje idinga ukubekwa ezingeni le-nanometer. Izikwele ze-ceramic kanye nezingxenye zesakhiwo zisebenza “njengereferensi eyinhloko” yesigaba se-wafer. Isilinganiso sazo sokuqina okuphezulu kuya kwesisindo sivumela ukusheshisa okusheshayo ngaphandle kokudlidliza noma “ukukhala” okuhlotshaniswa nezinto ezisindayo.

2. Ukuhlolwa kwe-Wafer kanye ne-Metrology

Ezinhlelweni ze-geometry ze-wafer, ama-Ceramic Master Squares asetshenziselwa ukulinganisa ukujiya kanye nokuqondile kwama-scanning axes. Ngenxa yokuthi i-ceramic igcina isimo sayo eminyakeni eyishumi, le mishini idinga imijikelezo embalwa kakhulu yokulinganisa kabusha, okwandisa isikhathi sokusebenza kwe-fab.

3. Ukuhlanganiswa Okunembile Kwamagumbi Okuhlanza I-Vacuum

Ukuhlanganiswa kwe-semiconductor kuvame ukwenzeka ezindaweni zokuhlanza lapho ukugcotshwa kulinganiselwe khona. Ama-ceramic gages ahlinzeka ngokunembile "komile" okungeke kukhiphe igesi noma kungcolise i-vacuum, okuqinisekisa ukuthi izingxenye zangaphakathi zihambisana nokubekezelelana kwe-sub-micron.

4. Ukuhlolwa Kwe-elekthronikhi Okuvame Kakhulu

Ekuhlolweni kwe-chip okusheshayo, noma yikuphi ukuphazamiseka okubangelwa amandla kazibuthe noma ugesi kusuka ethuluzini lokulinganisa kungaphazamisa imiphumela. Imvelo ye-alumina ceramic engeyona amandla kazibuthe iyenza ibe yinto efanelekile yokulungiswa kwamakhadi e-probe kanye nokulinganisa ukulingana.

5. Ochwepheshe Bokulinganisa Amakamelo Okuhlanza

Emakamelweni okuhlanza e-ISO Class 1, ukugqwala kuyinto engcolile engavunyelwe. Amageji ensimbi adinga amafilimu kawoyela ukuvimbela i-oxidation, okuyingozi enkulu yokungcola. Amageji e-ceramic awadingi uwoyela futhi angahlanzwa nge-isopropyl alcohol, agcine iphrofayili "yezinhlayiya ezingenalutho" iminyaka engaphezu kwengu-10.

"Inzuzo Yeminyaka Eyi-10"

Nakuba amageji ensimbi angagobeka noma aguge ngemva kweminyaka embalwa yokusetshenziswa kakhulu, isakhiwo sama-molecule se-Alumina ehlanzekile kakhulu sizinzile kakhulu. Uma sisetshenziswa njenge-Ceramic Square noma i-Straight Edge, ubulukhuni bale nto (esondela kobe-sapphire) buvimbela ukuwohloka kobuso obuncane obuvame ukubangela ukunemba "ukukhukhuleka" ngokuhamba kwesikhathi.

Ku-OEM ye-semiconductor, lokhu kusho ukwehla okuphindwe kayishumi kwezindleko zokugcinwa kwesikhathi eside kanye nezinga eliphakeme kakhulu lokuthembela ekunembeni komshini impilo yonke.
