SiCOI wafer 4inch 6inch HPSI SiC SiO2 Si subatrate imiterere

Ibisobanuro bigufi:

Iyi nyandiko igaragaza incamake irambuye ya Silicon Carbide-on-Insulator (SiCOI), cyane cyane yibanda ku bice bya santimetero 4 na santimetero 6 bifite ibice bya santimetero 25 bifatanye na silicon dioxide (SiO₂) hejuru ya silicon (Si). Imiterere ya SiCOI ihuza imiterere idasanzwe y'amashanyarazi, ubushyuhe, n'imikorere ya SiC hamwe n'inyungu z'amashanyarazi zo mu gice cya okiside hamwe n'inkunga ya silicon. Gukoresha HPSI SiC byongera imikorere y'igikoresho binyuze mu kugabanya uburyo substrate itwara kandi ikagabanya igihombo cya parasite, bigatuma izi wafer ziba nziza ku bikoresho bya semiconductor bifite ingufu nyinshi, inshuro nyinshi, n'ubushyuhe bwinshi. Uburyo bwo gukora, imiterere y'ibikoresho, n'ibyiza by'imiterere y'iyi miterere y'ibice byinshi biraganirwaho, bishimangira akamaro kabyo ku bikoresho by'amashanyarazi byo mu gisekuru gitaha na sisitemu za microelectromechanical (MEMS). Ubushakashatsi kandi bugereranya imiterere n'ikoreshwa rishoboka rya wafer za SiCOI zifite santimetero 4 na santimetero 25, bigaragaza ubushobozi bwo kwaguka no guhuza ibikoresho bya semiconductor bigezweho.

Imiterere ya SiCOI Wafer

SiCOI (Silicon Carbide on Insulator) ni imiterere yihariye ya wafer ihuza silicon carbide (SiC) n'urwego rukingira, rumeze nka SOI (Silicon-on-Insulator) ariko rworoheye gukoreshwa mu bushyuhe bwinshi/bukomeye. Ibiranga by'ingenzi:

Imiterere y'urutonde:

Urwego rwo hejuru: Silikoni Karubide imwe y'ikirahure (SiC) ifasha mu kugenda neza kwa electron no kudahungabana k'ubushyuhe.

Ingufu zishyirwa mu cyuma: Ubusanzwe SiO₂ (okiside) cyangwa diyama (muri SOD) kugira ngo bigabanye ubushobozi bwa parasite no kunoza uburyo bwo kwitandukanya.

Substrate y'ibanze: Silikoni cyangwa polycrystalline SiC yo gushyigikira ikoranabuhanga

Imiterere ya wafer ya SiCOI

Imiterere y'amashanyarazi Icyuho kinini (3.2 eV kuri 4H-SiC): Gitanga ingufu nyinshi zo kwangirika (>10× hejuru ya silikoni). Bigabanya amazi asohoka, bikongera imikorere myiza mu bikoresho by'amashanyarazi.

Ubushobozi bwo kugenda bwa Electron nyinshi:~900 cm²/V·s (4H-SiC) ugereranyije na ~1,400 cm²/V·s (Si), ariko imikorere myiza kurushaho.

Ubudahangarwa buke:Transistors zishingiye kuri SiCOI (urugero, MOSFET) zigaragaza igihombo gito cyo gutwara.

Ubwishingizi bwiza cyane:Okiside yahishwe (SiO₂) cyangwa urwego rwa diyama bigabanya ubushobozi bwa parasite na crosstalk.

Imiterere y'ubushyuheUbushobozi bwo gutwara ubushyuhe bwinshi: SiC (~490 W/m·K kuri 4H-SiC) ugereranije na Si (~150 W/m·K). Diyama (niba ikoreshejwe nk'icyuma gikingira) ishobora kurenza 2.000 W/m·K, bigatuma ubushyuhe bugabanuka.

Guhagarara neza k'ubushyuhe:Ikora neza kuri >300°C (ugereranyije na ~150°C kuri silikoni). Igabanya gukonjesha mu bikoresho by'ikoranabuhanga bikoresha ingufu.

3. Imiterere ya mekanike n'imitiUbukomere Bukabije (~ 9.5 Mohs): Irwanya kwangirika, bigatuma SiCOI iramba mu bidukikije bikomeye.

Ubudakora neza bw'ibinyabutabire:Irwanya ogisijeni n'ingufu, ndetse no mu gihe cy'aside/alkali.

Kwaguka k'ubushyuhe buke:Bihuye neza n'ibindi bikoresho bishyuha cyane (urugero, GaN).

4. Ibyiza by'imiterere (ugereranije na Bulk SiC cyangwa SOI)

Kugabanuka kw'ibihombo bya substrate:Uburyo bwo gukingira umuyaga burabuza amazi kwinjira mu gice cy'ubutaka.

Imikorere ya RF Yarushijeho Kuba myiza:Ubushobozi buke bwa parasite butuma habaho kwihuta mu guhinduranya (bifasha ibikoresho bya 5G/mmWave).

Igishushanyo mbonera cyoroshye:Uduce duto twa SiC two hejuru twemerera ikoranabuhanga ryo kunoza imikorere y'ibikoresho (urugero, imiyoboro mito cyane muri transistors).
