Ipleyiti yokupholisha i-wafer ye-ceramic ye-alumina engama-99.7%, njengesixhobo se-ceramic esisebenza kakuhle, isetyenziswa kakhulu kushishino lwe-semiconductor ngenxa yeempawu zayo zomzimba nezekhemikhali ezibalaseleyo. Eli nqaku lihlola iimpawu zeIpleyiti yokupolisha i-wafer ye-ceramic ye-alumina engama-99.7%kunye nendima yazo ebalulekileyo ekuvelisweni kwee-semiconductor.
1. Iipropati ze-99.7% ze-Alumina Ceramics
I-99.7% ye-alumina ceramic yinto ecocekileyo kakhulu eyenziwe ikakhulu yi-α-alumina (Al₂O₃). Iimpawu zayo eziphambili ziquka:
Ubunyulu obuphezulu:Umxholo we-alumina oyi-99.7% uqinisekisa uzinzo lweekhemikhali, nto leyo enciphisa umngcipheko wongcoliseko kwiinkqubo ze-semiconductor.
Ukumelana nobushushu obuphezulu:Izinzile kumaqondo obushushu angaphezulu kwe-1600°C, nto leyo eyenza ukuba ilungele iinkqubo zobushushu obuphezulu ezifana nokusasazwa, ukuxinana, kunye nokufakwa komphunga weekhemikhali (CVD).
Ukumelana nokugqwala:Iyamelana nee-asidi, ii-alkali, kunye neegesi ezirhabaxa, igcina uzinzo lokusebenza ngexesha lokugrumba kunye neenkqubo zokucoca.
Ukuqina Okuphezulu kunye nokumelana nokunxiba:Ubunzima obungaqhelekanga buqinisekisa ukuguguleka okuncinci xa usetyenziswa ixesha elide, nto leyo eyandisa ubomi benkonzo.
Ubushushu obuphezulu:Iimpawu ezibalaseleyo zokukhusela umbane zilungele iindawo ezifuna ukwahlulwahlulwa kombane.
2. Izicelo kwiMveliso yeSemiconductor
Ipleyiti yokupolisha i-wafer ye-ceramic ye-alumina eyi-99.7% idlala indima ebalulekileyo kwimveliso ye-semiconductor, kuquka:
Ukuphathwa kweWafer:Isetyenziselwa ukuqinisa nokuxhasa ii-wafers ngexesha le-lithography, i-etching, kunye ne-thin-film deposition, ukuqinisekisa uzinzo kwiindawo ezinobushushu obuphezulu kunye ne-corrosive.
Iinkqubo zoBushushu obuPhezulu:Iyamelana noxinzelelo lobushushu kwii-ovens zokusasazwa kunye nezixhobo ze-CVD, igcina uzinzo olulinganayo ukuthintela ukuguquka kwe-wafer.
Ukukrola kunye nokucoca:Ukusebenza okuxhathisa ukugqwala kuqinisekisa ukuqina kwiinkqubo zokugqwala ngeplasma kunye nokucoca okumanzi okubandakanya ii-asidi ezinamandla okanye ii-alkali.
Ukupakishwa kunye noVavanyo:Ibonelela ngeqonga elizinzileyo lokupakisha nokuvavanya iitships, ukuqinisekisa ukuchaneka kwenkqubo.
3. Iingenelo kunye nemingeni
Iingenelo ze-99.7% alumina ceramic wafer polishing plate zikwimeko yobunyulu bayo obuphezulu, uzinzo lobushushu, kunye nokumelana nokugqwala, ukuhlangabezana neemfuno ezingqongqo zemveliso ye-semiconductor. Nangona kunjalo, imingeni ibandakanya iinkqubo zokuvelisa ezintsonkothileyo, iindleko eziphezulu, kunye neemfuno ezingqongqo zokuthamba komphezulu kunye nokuchaneka kobukhulu, nto leyo ebeka imiqobo yobugcisa kwimveliso.
4. Imbono yexesha elizayo
Njengoko iteknoloji ye-semiconductor iqhubela phambili, iimfuno zokusebenza zeetreyi zeseramikhi ziya kuqhubeka zinyuka. Uphuhliso lwexesha elizayo lunokugxila ekuguqulweni kwezinto kunye neenkqubo zokuvelisa eziphuculweyo ukuphucula ukuhanjiswa kobushushu, amandla oomatshini, kunye nokusebenza kakuhle kweendleko, ukujongana neemfuno zokwenziwa kwe-semiconductor yesizukulwana esilandelayo.
