Menene farantin polishing na alumina mai tsarki mai tsabta?

Tare da saurin ci gaban masana'antar semiconductor, girman masana'antar ya ƙaru cikin sauri, kuma kayan aikin kera semiconductor sun ci gaba da canzawa zuwa daidaito da sarkakiya. Saboda yumbu suna da fa'idodin tauri mai yawa, babban modulus na roba, juriya mai yawa, babban rufi, juriyar tsatsa, ƙarancin faɗaɗawa, da sauransu, ana iya amfani da shi azaman sassan injin goge silicon, kayan aikin maganin zafi na epitaxial/oxidation/diffusion, injin lithography, kayan aikin adanawa, kayan aikin etching na semiconductor, injin dasa ion da sauran kayan aiki, don haka bincike da haɓakawa da samar da sassan yumbu daidai suna shafar ci gaban masana'antar semiconductor kai tsaye. Bukatun fasaha na shirye-shiryensa suna ƙaruwa da ƙaruwa.

Tsarkakken alumina, 99.7%-99.9% alumina.
Babban ƙarfin injina, juriyar lalacewa mai yawa, babban rufin lantarki, kwanciyar hankali mai yawa na sinadarai, kyakkyawan juriyar zafi da juriyar tsatsa. A halin yanzu, amfani da wafer silicon semiconductor na niƙa faifan yumbu shine mafi inganci kuma mafi inganci hanyar niƙa. Ana amfani da hanyar niƙa mai gefe biyu don niƙa wafer silicon da aka yanke, kuma ingancin wafer ɗin niƙa yana inganta ta hanyar inganta tsarin niƙa (kayan diski, ruwan niƙa, matsin lamba da saurin niƙa, da sauransu). Musamman, amfani da faranti na yumbu maimakon faranti na ƙarfe, don guje wa niƙa a babban saman wafer da tabo ko gurɓatawa ke haifarwa, rage shigar da ions na ƙarfe, na iya rage sarrafa silicon na gaba, rage lokacin tsari (lalata) na gaba, inganta ingancin samarwa, da rage asarar sarrafa silicon, inganta amfani da silicon sosai.

Farantin gogewa mai ƙarfi na alumina waferAna amfani da shi a fannin semiconductor, man fetur, sinadarai, photovoltaic, ruwa crystal da sauran masana'antu, kamar sassan injiniya, sassan lantarki, faifan shigarwa na microwave, kayan rufi da sauran sassa, na'urorin semiconductor, kayan injinan injina, kayan injina na injina, kayan injina na injina na ruwa da sauran sassa. Babban girma da tsarkin yumbu na alumina suna da mahimmancin amfani a masana'antar sapphire da masana'antar guntu na semiconductor. Yana da babban tallafi kuma ana amfani da shi don gogewa ta injiniyan sinadarai (CMP) na wafers na sapphire da semiconductor silicon. Hakanan ana iya amfani da yumbu na alumina mai girma da tsarki azaman madadin alumina don LCD.
