Cov Khoom Siv Qhia Txog Khoom

3-nti 4H semi-insulated SiC (silicon carbide) substrate wafers yog cov khoom siv semiconductor uas siv ntau. 4H qhia txog cov qauv siv lead ua tetrahexahedral. Semi-insulation txhais tau tias lub substrate muaj cov yam ntxwv tiv taus siab thiab tuaj yeem cais tawm ntawm cov dej ntws tam sim no.

Cov wafers substrate no muaj cov yam ntxwv hauv qab no: kev ua haujlwm kub siab, kev poob qis, kev tiv taus kub zoo heev, thiab kev ruaj khov kho tshuab thiab tshuaj lom neeg zoo heev. Vim tias silicon carbide muaj qhov sib txawv zog dav thiab tuaj yeem tiv taus qhov kub siab thiab cov xwm txheej hluav taws xob siab, 4H-SiC semi-insulated wafers tau siv dav hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob zaus (RF).

Cov ntawv thov tseem ceeb ntawm 4H-SiC semi-insulated wafers suav nrog:

1--Cov khoom siv hluav taws xob fais fab: 4H-SiC wafers siv tau los tsim cov khoom siv hloov hluav taws xob xws li MOSFETs (Metal Oxide Semiconductor Field Effect Transistors), IGBTs (Insulated Gate Bipolar Transistors) thiab Schottky diodes. Cov khoom siv no muaj kev poob qis thiab kev hloov pauv hauv qhov hluav taws xob siab thiab qhov kub thiab txias thiab muab kev ua haujlwm zoo dua thiab kev ntseeg siab.

2--Cov Khoom Siv Xov Tooj Cua Zaus (RF): 4H-SiC semi-insulated wafers siv tau los tsim cov hwj chim siab, cov RF fais fab amplifiers, chip resistors, lim dej, thiab lwm yam khoom siv. Silicon carbide muaj kev ua tau zoo dua thiab thermal stability vim nws qhov electron saturation drift rate loj dua thiab thermal conductivity siab dua.

3--Cov khoom siv Optoelectronic: 4H-SiC semi-insulated wafers siv tau los tsim cov high-power laser diodes, UV lub teeb detectors thiab optoelectronic integrated circuits.

Hais txog kev lag luam, qhov kev thov rau 4H-SiC semi-insulated wafers tab tom nce ntxiv nrog rau kev loj hlob ntawm cov khoom siv hluav taws xob, RF thiab optoelectronics. Qhov no yog vim qhov tseeb tias silicon carbide muaj ntau yam kev siv, suav nrog kev siv hluav taws xob zoo, tsheb fais fab, lub zog rov ua dua tshiab thiab kev sib txuas lus. Yav tom ntej, kev lag luam rau 4H-SiC semi-insulated wafers tseem muaj kev cia siab heev thiab xav tias yuav hloov cov ntaub ntawv silicon ib txwm muaj hauv ntau yam kev siv.
