Ubumsulwa bediski yepleyiti epholisiweyo ye-alumina ceramic wafer buyichaphazela njani le nkqubo?

Ubunyulu beiidiski zepleyiti zokupolisha ze-alumina ceramicinempembelelo enkulu kule nkqubo, ingakumbi kwezi ndawo zilandelayo:

1. Isiphumo sokupolisha:

- Iidiski ezicociweyo ze-alumina wafer ezicocekileyo kakhulu zibonelela ngomphezulu ocociweyo ofanayo oneziphene ezimbalwa kunye nokungcola komphezulu.

- Ukusetyenziswa kwee-wafers ze-semiconductor disc ze-aluminium oxide polishing disc ezinobunyulu obuphezulu kunokunciphisa umphezulu ophambili wee-wafer scarves okanye ungcoliseko, kunciphise ukungena kwee-ion zesinyithi, kuphucule ukusetyenziswa kwee-silicon wafers kunye nomgangatho wokupolisha.

2. Umgangatho wemveliso:

- Ubunyulu obuphezulu beediski zepleyiti ezipholisiweyo ze-alumina ceramic buthetha ukuba umxholo wazo wokungcola uphantsi, nto leyo enokunciphisa ungcoliseko lomphezulu we-wafer olubangelwa kukungcola ngexesha lenkqubo yokupholisha.

- Iidiski zokupolisha ezicocekileyo kakhulu zinceda ukugcina ubunyulu bemveliso, ukuqinisekisa ukusebenza okuzinzileyo kwezixhobo ze-semiconductor kunye nokuhlangabezana neemfuno ezingqongqo zenkqubo.

3. Uzinzo lwenkqubo:

- I-coefficient yokwandiswa kobushushu beediski zokupholisha ze-alumina ezicocekileyo kakhulu iyafana neye-silicon, enceda ukunciphisa uxinzelelo lobushushu olubangelwa kukutshintsha kobushushu kunye nokuphucula uzinzo lwenkqubo.

- Inkqubo ezinzileyo inceda ekunciphiseni izinga elingalunganga kwinkqubo yemveliso kunye nokuphucula ukusebenza kakuhle kwemveliso.

4. Uzinzo lweekhemikhali:

- I-alumina ecocekileyo kakhulu inozinzo oluhle kakhulu lweekhemikhali kwaye iyakwazi ukugcina iipropati kunye nolwakhiwo lwayo kwiindawo ezahlukeneyo zeekhemikhali.

- Oku kwenza iidiski zokupolisha ze-aluminium oxide ezicocekileyo kakhulu zingachaphazeleki kakhulu kukugqwala okanye ukuguguleka ngexesha lenkqubo yokupolisha kwaye zigcina ubomi benkonzo obude.

5. Iingenelo zoqoqosho:

- Nangona ixabiso lokuqala lediski yokupholisha ye-alumina ecocekileyo kakhulu linokuba phezulu, iimpawu zayo ezintle kunye nobomi bayo obude kunciphisa iindleko zemveliso iyonke.

- Ukongeza, iidiski zokupholisha ezicocekileyo kakhulu zinokuphucula umgangatho wemveliso kunye nokuzinza kwenkqubo, zinciphise izinga lemveliso elingalunganga, kwaye ziphucule ngakumbi iingenelo zoqoqosho.

6. Impembelelo yezalathisi zobugcisa:

- Ngokwenqaku elikhankanyiweyo, iidiski zokupolisha ze-alumina ecocekileyo kakhulu (99.7%-99.9%) zineempawu ezintle kakhulu zomzimba nezekhemikhali, ezinje ngamandla aphezulu oomatshini, ukumelana nokuguguleka okuphezulu, ubushushu obuphezulu bombane, ukuzinza okuphezulu kweekhemikhali, ukumelana nobushushu obuhle kunye nokugqwala.

- Ezi zibonakaliso zobugcisa zichaphazela ngqo impembelelo yenkqubo yokupolisha kunye nomgangatho wemveliso.

Ucoceko lwediski yepleyiti epholisiweyo ye-alumina ceramic wafer lunempembelelo ebalulekileyo kwinkqubo, idiski yokupholisha epholisiweyo enokuphucula isiphumo sokupholisha, umgangatho wemveliso kunye nozinzo lwenkqubo, ngelixa kunciphisa iindleko zemveliso iyonke. Ke ngoko, kwinkqubo yokuvelisa i-semiconductor, ukukhetha iidiski zokupholisha ze-alumina ezipholisiweyo kubalulekile ukuqinisekisa umgangatho wemveliso kunye nokuphucula ukusebenza kakuhle kwemveliso.
