Nā mea a me nā hiʻohiʻona o nā subramic countrage

Me ka holomua a me ka hoʻomohalaʻana i kaʻenehana, ke kaʻina hana o ka hanaʻana, a me nā hana hana a me nā neʻeʻana i nā mea hana. I mea e hoʻokō ai i ka hilinaʻi o nā mea hana a me nā circuats, ua kauʻia nā koi kiʻekiʻe i mua o nā mea lawe chip. Ua hoʻohana nuiʻia nā submic i kēia mau mahina no ko lākou mau māla no ko lākou mau waiwai maikaʻi loa

I kēia manawa, ʻo nā mea waiwai nui i hoʻohanaʻia ma Cubic Bastrates: Alumina (Al2O3)

Eʻike i nā hiʻohiʻona pōkole o kēia mau 5 mau papa hana holomua no nā mea e like me kēia:

1. Alumina (al2o3)

Al2o3 homogenous polycrysstals hiki iā ia ke loaʻa ma mua o 10 mauʻano he 10 mauʻano nui loa: α-al2o3, z-al2o3. I waena o lākou, α-Al2o3 kahi hana haʻahaʻa loa aʻo ia ka paʻa o ka pākaha bomaka waena o kaʻohuʻo Rhobdal. ʻO α-Al2O3 ka hana paʻa, hiki ke kauʻia i keʻano, hiki ke loaʻa ma nā wela a pau; I ka wā e loaʻa ai ka mahana i ka 1000 ~ 1600 ° C, e hoʻololiʻia nāʻano'ē aʻe i nā loli i loko o α-al2o3.

Kiʻi 1:ʻO ka Microstal Microstruture o Al23 ma lalo o ka sem

Me ka hoʻonuiʻana o Al2O3 nui a me ka hōʻemiʻana o ka hapa nui o ke aniani e pili ana i ka nui o al2o3 ma keʻano he al23. 90%.

ʻOiai e hoʻonui ana i ka hapa nui o al2o3 e hoʻomaikaʻi i ka hana holoʻokoʻa, e hoʻonui ana i ka hopena o nā cemaration, he alakaʻiʻia ana i ka ukuʻana i nā uku hana.

2. Alminim Nitride (Aln)

ʻO Aln kahiʻano hui o ka hui ⅲ-v coupound me wurtzite hoʻonohonoho. ʻO kāna kikowaena kikowaena aln4 terahedron,ʻo ia ka mea e pono aiʻo Hexagonal Crystal me ka ikaika a me ka ikaika loa o keʻano. Aretitically, nona kona hana crystal ka cristral i ka marm3, no laila, heʻano hermal hermal o 320 k? Hiki i ka substrate hiki iā 150w / (m · m · ma mua o 5 mau manawa o al2o3. ʻO ka papa inoa o ka Haina Vepanson he 3.8 × 10-6 ~ 4.4 × 10-6 / IT

Kiʻi 2:ʻO ka pauka o Alumini nitride

Uaʻoi aku ka nui o nā aln cherambic ma mua o nā mea he al2o3 mau manawa hou, e hoʻololi pono ana i nā mīkini al2o3 e koi ana i nā mana al2o3. Ua manaʻoʻiaʻo Aln Cerramics e like me ka mea i makemakeʻia no ka puka makani o ka ikehu o ka mana o ka mana o ka mana o nā electronic colcouch elember colcould ma muli o ko lākou mau haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa.

3. Silicon nitride (si3n4)

SI3N4ʻO ka hui pūʻana me nā mea i hoʻopaʻaʻia meʻekolu mau mea kani: α-si3n4, β si3n4, a me γn4, a me γn4. I waena o lākou, α-si3n4 a Β-si3n4ʻO nāʻano cristal maʻamau,ʻo ia kaʻano hexagonal maʻamau. ʻO ke kolohe o ka moʻomeheu o ke aloha kūmoleʻo SI3ND ke hiki iā 400w / (m · m · (k? Eia nō naʻe, ma muli o kāna hanaʻana i ka uila phonon, aia nā hewa i ka paleʻana e like me ka halaʻole o nā cramusy maoli e hoʻonui wale ana . ^. Ma kaʻaeʻana i ka hoʻohālikelike a me ka hana hewa, ua hiki aku ka hana o ka thermal i 106w / (m · m · ʻO ka hōʻoia o kaʻatikala ma Si3n4 ma kahi o 3.0 × 10-6-6-6-6-6 / C, e hana ana i nā mea hoʻonaninani likeʻole.

Kiʻi 3: Powder o SiliKi Nitride

I waena o nā mea i kauʻia ma ke kauʻana,ʻo SI3N4 keʻano o nā mea lapaʻau maikaʻi loa, he congalleni kiʻekiʻe a me ka paleʻana o ka corallent. I kēia manawa, ua makemakeʻia ma Igbt Module Pounding a hoʻololi hou iā Al2O3

4.silinic i kāwele (sic)

ʻIkeʻiaʻo SECS CrySTal SIC i kapaʻiaʻo ia ka meaʻekolu semicohonstucors, ua loaʻa nā kumukūʻai nui o ka ranahi nui.

Ma ka hoʻohuiʻana i kahi liʻiliʻi o beo a me B2O3 i ka SIC e hoʻonui i kona paleʻana, a laila hiki iāʻoe ke hoʻomākaukau i ka hana hou o ka nui o ka mahana ma mua o 98% o nā mea hou o SICHERSING. ʻO ka mālamaʻana o ka thermal o nā cemics sicramics me nā lāʻau'ē aʻe i hoʻomākaukauʻia e nāʻano hana hewa a me nā hoʻohuiʻana he 100 ~ 490W / (m · m · (M · M · (M · M · (M · M · (M · M · (M · M · (M · M · (M · M · (M · M · (M · M · (M · M · (M · M · (M · M · (M · M · No ka mea, he nui loa ka nui o nā cemitric

5. Beryllia (Beo)

ʻO ka Beo heʻano hanaʻo Wurtzite a me ke kelepona cubic crystal crystal. He kiʻekiʻe loa kona hōʻinoʻana o kona halepule ʻAʻole wale kekahi mea e kūleʻa ai i ka hoʻokūkūʻoi aku ka kiʻekiʻe, akā he haʻahaʻa haʻahaʻa haʻahaʻa a me nā mea hōʻoia o ka coextric,ʻo BEO e koi ana i nā mea kūʻai nui kiʻekiʻe.

Kiʻi 5:ʻO keʻano o ka crystal o Beryllia

ʻO keʻano o keʻano a me nāʻano haʻahaʻa haʻahaʻa haʻahaʻa a me nā haʻahaʻa haʻahaʻa haʻahaʻa loa e ka mea i makemakeʻia e nā mea hana'ē aʻe, akā he mau pōkole nui loa ka beo.

I kēia manawa, hoʻohana pinepineʻia nā mea hana maʻamau ma Kina he al2o3, Aln a sri3n4. Hiki i ka subsramic substrate i hanaʻia e kaʻenehana ltc e hoʻohui i nā mea i loaʻa e like me nā mea hou, a me nā mea hiki ke loaʻa i ka hanaʻekolu. I ka hoʻohālikelikeʻana i ka hoʻohuiʻana o nā semiconductors o nā semiconductors,ʻo ia nō nā mea hana ikaika loa, ltcc he kiʻekiʻe-density 3d interconnect.
