Izixhobo zeCeramic ze-Alumina eziKhuselekileyo ze-ESD zoLawulo lweWafer oluSensitive-Sensitive
Izixhobo ze-alumina ezikhuselekileyo zeSt.Cera's ESD (electrostatic discharge) zenziwe nge-99.8% ye-Al₂O₃ ecocekileyo kakhulu enokumelana nomphezulu okwenzelwe wena we-10⁶–10⁹ Ω/sq, efumaneka ngenkqubo yokusetyenziswa kwe-doping okanye yokugquma. Ezi zixhobo zisusa ngempumelelo itshaja engashukumiyo, zithintela umonakalo we-electrostatic kwii-wafers ze-semiconductor ezibuthathaka kunye nezixhobo. Izinto ezisisiseko zigcina amandla azo aphezulu e-flexural (361 MPa), ubunzima (16 GPa), kunye namandla e-dielectric (15×10⁶ V/m). Izixhobo ze-ceramic ezikhuselekileyo ze-ESD ziquka izixhobo zokugqibela, iiphini zokuphakamisa, iireyile zesikhokelo, kunye nezixhobo ezenziwe ngokwezifiso ze-FAB automation.

Qaphela: Ukumelana nomphezulu we-ESD akubonelelwa kwiitheyibhile zeempawu zezinto ezibonelelweyo. Olu luhlu lungentla lusemgangathweni weshishini kwiiseramikhi ezisasaza izinto. Nceda unxibelelane nathi ukuze ufumane iingxelo zovavanyo.
Izicelo:
● Izixhobo zokuphelisa ezikhuselekileyo ze-ESD zokudlulisa i-wafer
● Izikhonkwane zokumisa umhlaba kunye nezixhobo ze-ESD kwizixhobo ze-FAB
● Vavanya iisokhethi zezixhobo ezibuthathaka ezingashukumiyo
● Izixhobo zokucoca apho ulawulo olungaguqukiyo lubaluleke kakhulu
Ukuvelisa kunye noMgangatho:
Ukulungiswa kwe-alumina okuqhelekileyo + unyango lomphezulu we-ESD → ukuchasana komphezulu kulinganiswa ngokwe-ANSI/ESD STM11.11. Inxalenye nganye ivavanywa nge-100% nge-electrode yeringi engqindilili.
Iingenelo:
● Ithintela ukulahleka kwesivuno okunxulumene ne-ESD
● Igcina amandla oomatshini beceramic kunye nokumelana neekhemikhali
● Akukho kuveliswa kwamasuntswana avela ekukhutshweni okungaguqukiyo
