Wafer silicon Carbide nke nwere ihe dị ka sentimita atọ n'obosara, nke dị sentimita iri na isii n'obosara, nke nwere ihe dị ka sentimita iri anọ ...

Wafer Silicon Carbide nke nwere ihe mkpuchi SiC nke dị sentimita 3, nke dị sentimita 76.2mm, nke nwere ihe mkpuchi 4H-Semi SiC nke na-akparị mmadụ, nke a na-ahụ anya na foto a na-egosi.

Nkọwa Dị Mkpirikpi:

Wafer SiC nke otu kristal dị elu (Silicon Carbide) maka ụlọ ọrụ eletrọnịkị na optoelectronic. Wafer SiC nke dị sentimita 3 bụ ihe eji emepụta semiconductor nke ọgbọ na-abịa, nke nwere ọkara mkpuchi silicon-carbide nke dayameta sentimita 3. E bu n'obi imepụta wafer ndị a maka ike, RF na ngwaọrụ optoelectronic.

Wafers nke SiC (silicon carbide) nke dị sentimita 3 n'obosara na ọkara nke nwere ihe mkpuchi semiconductor bụ ihe a na-ejikarị eme ihe na semiconductor. 4H na-egosi nhazi kristal tetrahexahedral. Ihe mkpuchi semi-mkpuchi pụtara na ihe mkpuchi ahụ nwere njirimara iguzogide dị elu ma enwere ike kewapụ ya na mmiri ọkụ.

Ihe ndị a nwere njirimara ndị a: ike ọkụ dị elu, obere mfu nke nnyefe, oke okpomọkụ dị elu, na ezigbo nkwụsi ike n'ihe gbasara igwe na kemịkalụ. N'ihi na silicon carbide nwere oghere ike sara mbara ma nwee ike iguzogide okpomọkụ dị elu na ọnọdụ ọkụ eletrik dị elu, a na-ejikarị wafers 4H-SiC nke nwere ọkara mkpuchi na ngwaọrụ eletriki ike na redio ugboro ugboro (RF).

Ngwa ndị bụ isi nke wafers 4H-SiC nke nwere ihe mkpuchi ọkara gụnyere:

1--Igwe eletrọniki Ike: Enwere ike iji wafers 4H-SiC rụpụta ngwaọrụ mgbanwe ike dịka MOSFETs (Metal Oxide Semiconductor Field Effect Transistors), IGBTs (Insulated Gate Bipolar Transistors) na Schottky diodes. Ngwaọrụ ndị a nwere obere mfu conduction na switching na gburugburu voltaji dị elu na okpomọkụ dị elu ma na-enye arụmọrụ na ntụkwasị obi dị elu.

Ngwaọrụ 2--Egwuregwu Radio Frequency (RF): Enwere ike iji wafers 4H-SiC nke nwere ọkara mkpuchi iji mepụta amplifiers ike dị elu, ndị na-eme ka ike RF dị elu, ndị na-eguzogide chip, nzacha, na ngwaọrụ ndị ọzọ. Silicon carbide nwere arụmọrụ ugboro ugboro dị elu na nkwụsi ike okpomọkụ ka mma n'ihi oke ọsọ njupụta electron ya na njikwa okpomọkụ dị elu.

3--Ngwaọrụ Optoelectronic: Enwere ike iji wafers 4H-SiC nke nwere ọkara mkpuchi eme ihe iji mepụta diode laser dị ike, ihe nchọpụta ọkụ UV na sekit optoelectronic agbakwunyere.

N'ihe gbasara ụzọ ahịa si aga, ọchịchọ maka wafers 4H-SiC nke ọkara-insulated na-amụba ka mpaghara eletrọniki ike, RF na optoelectronics na-eto eto. Nke a bụ n'ihi na silicon carbide nwere ọtụtụ ojiji, gụnyere arụmọrụ ike, ụgbọ ala eletrik, ike mmeghari ohuru na nkwukọrịta. N'ọdịnihu, ahịa maka wafers 4H-SiC nke ọkara-insulated ka dị mma nke ukwuu ma a na-atụ anya na ọ ga-anọchi ihe silicon nkịtị n'ọtụtụ ngwa.
