TDMAH

TDMAH, los yog Tetrakis (dimethylamido) hafnium, yog cov tshuaj sib xyaw nrog cov mis Hf[N(CH3)2]4. Nws yog xim tsis muaj xim, ntshiab kua nrog ib qho tsw ntxhiab tsw thiab soluble heev hauv cov kuab tshuaj organic. TDMAH feem ntau siv nyob rau hauv kev lag luam semiconductor ua ib qho chaw hafnium rau cov tshuaj vapor deposition (CVD) thiab atomic txheej deposition (ALD).

Nta:

TDMAH yog cov khoom siv ntshiab heev nrog rau qib siab ntawm reactivity thiab stability. Nws muaj qhov tsis tshua muaj vapor siab thiab yooj yim los daws, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau CVD thiab ALD cov txheej txheem. TDMAH kuj muaj cov thermal stability siab, ua rau nws haum rau siv nyob rau hauv high-temperature daim ntaub ntawv.

Qib:

TDMAH muaj nyob rau hauv ntau qib, suav nrog qib siab purity thiab ultra-high purity qib, kom tau raws li cov kev xav tau tshwj xeeb ntawm cov ntawv thov sib txawv.

Daim ntawv:

TDMAH feem ntau muaj raws li lub teeb daj crystalline khoom, los ntawm cov khoom me me mus rau cov khoom lag luam loj.

Txoj kev tsim khoom:

TDMAH yog tsim los ntawm reacting hafnium tetrachloride nrog dimethylamine nyob rau hauv cov organic hnyav raws li kev tswj xyuas. Cov khoom uas tau tshwm sim yog ces purified los ntawm distillation thiab lwm yam purification txoj kev kom tau raws li qhov xav tau qib thiab purity.

Daim Ntawv Thov & Lwm Cov Kev Lag Luam:

TDMAH feem ntau yog siv los ua ib qho hafnium hauv CVD thiab ALD cov txheej txheem hauv kev lag luam semiconductor. Nws kuj tseem siv rau hauv kev tsim cov khoom siv high-tech, nrog rau cov txheej txheem kho qhov muag, nanotubes, thiab ceramics. TDMAH yog ib qho tseem ceeb hauv kev tsim cov hafnium-based gate dielectrics, uas yog siv rau hauv cov khoom siv microprocessors thiab nco.

Health & Safety Information:

TDMAH yog cov nplaim hluav taws kub thiab corrosive kua thiab yuav tsum tau ceev faj. Nws tuaj yeem ua rau tawv nqaij, qhov muag, thiab ua pa, thiab tuaj yeem ua rau muaj kev phom sij yog tias noj lossis nqus tau. Cov cuab yeej tiv thaiv tus kheej tsim nyog yuav tsum tau hnav thaum tuav TDMAH, thiab nws yuav tsum muab khaws cia thiab siv rau hauv qhov chaw muaj cua zoo.
