The High Purity Quartz Bell Jar yochokera ku Semicera idapangidwa kuti igwiritsidwe ntchito m'malo opangira ma semiconductor apamwamba. Wopangidwa kuchokeraquartz yapamwamba kwambiri, botolo la belu ili ndiloyenera kwa makina otsekemera,mtandamakutidwe ndi okosijeni, ndi njira zochepetsera mukupanga semiconductor. Ndi kumveka kwake kwapadera komanso chiyero, imatsimikizira malo opanda kuipitsidwa, ofunika kwambiri pa njira za CVD ndi ntchito zolondola kwambiri.
Semicera's High Purity Quartz Bell Jar ndiyoyeneranso zipinda zovundikira mabelu, zomwe zimapereka kukana kwamafuta komanso mankhwala. Kugwiritsiridwa ntchito kwake m'malo ovuta kwambiri monga oxidation wa wafer ndi njira zowotchera zimatsimikizira kuti zimagwira ntchito bwino komanso zimakhala zolimba.
Pazinthu zomwe zimafunikira zida zoyeretsedwa kwambiri, monga zida za semiconductor quartz, botolo la belu la quartz ili limapereka zotsatira zodalirika. Kapangidwe kake kolimba kamathandizira zotsatira zosasinthika pamakina a vacuum ndikuwonjezera magwiridwe antchito a CVD. Kaya imagwiritsidwa ntchito mumtsuko wa belu wa belu kapena mtsuko wa belu wagalasi kuti mugwire bwino, imatsimikizira kugwira ntchito kwapamwamba komanso moyo wautali.
Iziquartz yoyera kwambirinjira yothetsera vutoli ndi gawo lofunika kwambiri kuti tipeze zotsatira zenizeni pakupanga semiconductor, ndikupangitsa kukhala chisankho choyenera kwa mafakitale omwe kulondola ndi kuyera ndizofunikira kwambiri.
