Mufananidzo: Mainjiniya weIVWorks ari kugadzirisa sosi yeplasma kuti ishandiswe muHybrid MBE system, ichitsigira kukura kweGaN epitaxial yemhando yepamusoro uye ine hunhu hwakanaka.
Transistor ine gallium nitride (GaN) ine maelectron-mobility transistor (HEMT) inosanganisira tekinoroji ye reGaN selective regrowth yeIVWorks Co Ltd yeDaejeon, South Korea yava transistor yekutanga pasi rose yeGaN kuwana oscillation frequency yakanyanya (f).zvakanyanya) inodarika 700GHz. Izvi zvakaratidzwa kuburikidza nemudziyo we45nm GaN HEMT wakagadzirwa nechikwata chevaongorori vapurofesa Dae-hyun Kim muSchool of Electronics Engineering paKyungpook National University uye wakaburitswa musi wa18 Chikumi pa2026 IEEE/JSAP Symposium on VLSI Technology & Circuits muHonolulu, Hawaii, USA.
Chikwata chekutsvagisa chakagadzira transistor yeGaN ine urefu hwegedhi re45nm uye chakawana rekodhi repamusoro rezvakanyanyaye742GHz, zvichigadzira chiyero chitsva chekushanda kweRF muGaN transistor tekinoroji. Mudziyo uyu wakawanawo avhareji yefrequency metric (favg) ye497GHz, kukosha kwepamusoro-soro kwakataurwa kusvika pari zvino kune chero tekinoroji yeGaN transistor. Mhedzisiro iyi inoratidza kuti GaN semiconductors ine kukwikwidza kwakakwana kwekushanda kunyangwe muhurongwa hwe ultra-high-frequency uye inogona kushanda sepuratifomu inoshanda kune remangwana sub-terahertz uye terahertz electronic systems, inodaro IVWorks.
Kunyange hazvo ma transistors e indium phosphide (InP)-based ave achitonga sub-terahertz frequency regime kwenguva refu nekuda kwehunhu hwavo hwekutakura ma electron hwakasiyana, voltage yavo yakaderera yekupwanyika inoderedza simba rekubuda uye scalability yesystem. Kusiyana neizvi, GaN inopa musanganiswa wakasiyana wemagetsi akanyanya kupwanyika, simba rakawanda, uye kusimba kwekupisa kwakanaka, zvichiita kuti ive vamiriri vanokwezva kune mashandisirwo emagetsi echizvarwa chinotevera ane ma frequency akakwira uye ane simba rakawanda. Zvisinei, kuwana mashandiro e ultra-high-frequency neGaN kwakaramba kuri dambudziko guru. Kuti vakunde zvipingamupinyi izvi, timu yekutsvagisa yakashandisa nzira yepamusoro ye 45nm gate process uye optimized device architecture kuti iwedzere mashandiro e high-frequency.
Chinhu chakakosha chaive tekinoroji yeIVWorks yekusarudza reGaN. Yakagadzirwa neIVWorks chete, reGaN inokurazve GaN yakawanda munzvimbo dzinowanikwa mvura uye dzinodonhedzwa nemvura, zvichideredza zvakanyanya kuramba kwekubatana. Semumwe wevabatsiri muongororo iyi, IVWorks yakaratidza izvo zvinonzi zvakafanana pakugadzira michero yese ye 4-inch wafer uye yakawana mukana wekuwedzera zvakare. Uyezve, kambani iyi yakaderedza kuramba kwe regrowth interface (R).mukati) kusvika ku0.027Ω-mm, zvichisvika pamuganho wedzidziso unogoneka pahuwandu hwemutakuri hunoenderana.
"Tsvagiridzo iyi inosundira miganhu yekushanda kweRF yeGaN HEMTs padanho idzva uye inoratidza kugona kweGaN semiconductors pakushandisa ma ultra-high-frequency kuburikidza nekuratidzira kwekutanga pasi rose kweGaN HEMT ine h inodarika 700GHz," anodaro purofesa Dae-hyun Kim. "Chidzidzo ichi chine kukosha kwakanyanya semuenzaniso wakabudirira wekushandira pamwe kweindasitiri nedzidzo, kusanganisa tekinoroji yepamusoro yekukura kwe epitaxial uye regrowth kubva kuindasitiri nehunyanzvi hweyunivhesiti mukutsvaga kwemidziyo nedunhu," anowedzera.
"Tichivakira pane izvi, tinoronga kukurumidzisa kugadzirwa kwemidziyo yemagetsi yechizvarwa chinotevera yeGaN inotarisa mashandisirwo e terahertz-frequency ekutaurirana kwe6G uye matekinoroji ekudzivirira epamusoro."
IVWorks inoti kubudirira uku kunoratidzawo kukura kwehunyanzvi hweGaN hwekuwedzera kupfuura RF yechinyakare uye simba remagetsi kuenda kumashandisirwo ari kubuda e sub-terahertz ne terahertz, kusanganisira kutaurirana kwe6G, masisitimu eradar epamusoro, kutaurirana kwesatellite, uye midziyo yekudzivirira yechizvarwa chinotevera.
"ReGaN inyanzvi huru ye tekinoroji yakatopfuura hunyanzvi hwemhando yepamusoro pafekitori huru uye yave kushandiswa kugadzira huwandu hwezvinhu," anodaro CEO weIVWorks, Young-kyun Noh. "Chiitiko ichi chinoratidza kuti puratifomu yedu yereGaN yakavakirwa paHybrid-MBE haisi kungogadzirira kugadzirwa chete asiwo tekinoroji yakakosha yechizvarwa chinotevera che sub-terahertz ne terahertz GaN electronics," anowedzera. "Tinodada kuona tekinoroji yeIVWorks ichibatsira padanho repamusoro rekutsvagisa pasi rose."
