Molybdenum Disc
Molybdenum disks tau dav siv los ua cov khoom sib txuas hauv thyristor rectifier diodes, transistors thiab thyristors (GTO'S).
Hauj lwm lawm
Niaj hnub no, molybdenum yog cov khoom ntawm kev xaiv rau mounting cov ntaub ntawv nyob rau hauv lub hwj chim semiconductor pab kiag li lawm, tshwj tsis yog rau ib co tshwj xeeb daim ntaub ntawv, vim nws cov nqi qis heev thiab lub teeb yuag. Ob qho khoom siv, piv txwv li silicon thiab molybdenum, muaj tib coefficient ntawm kev nthuav dav thiab ob qho tib si muaj cov thermal conductivity siab, uas ua rau lawv xav tau, tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob loj uas tsim kom muaj cua sov ntau. Cov ntawv thov ntxiv muaj xws li kev siv molybdenum ua lub hauv paus cua sov rau cov khoom siv hluav taws xob semiconductor, kev sib xyaw ua ke loj loj, thiab hybrid circuits.

GNEE tshwj xeeb hauv kev tsim cov purity siab molybdenum wafers nrog qhov siab tshaj plaws ua tau kom ceev thiab qhov tsawg tshaj plaws qhov nruab nrab cov qoob loo loj tshaj plaws rau cov khoom siv hluav taws xob, tshuaj vapor deposition (CVD) thiab lub cev vapor deposition (PVD) zaub thiab kev siv kho qhov muag. Peb tus qauv wafer qhov ntau thiab tsawg yog los ntawm 1 nti mus rau 8 nti inch thiab los ntawm 2 hli mus rau 1/2 nti tuab. Peb kuj tuaj yeem muab cov discs sab nraud ntawm qhov chaw no. Peb tsim cov khoom siv crystallization, solid-state thiab lwm yam ultra-high purification txheej txheem xws li sublimation.
txog peb
Peb tau tsim thiab muab cov hlau zoo rau ntau xyoo thiab niaj hnub siv zog los txhim kho peb cov txheej txheem tsim khoom thiab cov khoom zoo. Peb lub hom phiaj yog lub ntiaj teb ua tus xa khoom ntawm cov hlau thiab niaj hnub nqis peev hauv cov chaw tsim khoom thiab thev naus laus zis, txhim kho cov kev pabcuam zoo thiab kev daws teeb meem kev thauj mus los, thiab ua ntej cov neeg siv khoom txaus siab.
