MOSFET: mahi me te hōkai o te parau tumu o

Te tai'oraa i te āhuatanga o te rauemi pērā i te Semiconductor, tukua ki te hanga āhuatanga hou. Neke atu i te hangarau i reira wa ki arumoni hua p, transistors Mos, thyristors me ētahi atu āhuatanga. pai te whakakapi ratou korere mārua, me te whakaaetia ki te ite i te whakaaro tino maia. E whakamahia wāhanga Semiconductor i roto i ao katoa o to tatou ora. te tauturu ia ratou ki a tatou te tukatuka moni nui o te kōrero i runga i te pūtake o ratou rorohiko e hangaia, rīpene tuhi, televisions, me ētahi atu

Mai te tenenga o te transistor tuatahi, a ko reira i roto i 1948, haere he wa roa. He nga rerekētanga o tenei huānga: ira germanium, silicon, mara-pānga transistor ranei MOSFET. Kei te whānui katoa o ratou whakamahia i roto i te taputapu hiko. Ko te ako o te āhuatanga o Semiconductors kore e mutu i roto i to tatou wa.

Kua arahina ēnei rangahau ki te putanga o te pūrere pērā i te MOSFET. Ko te parau tumu o te mahi kei te hāngai te reira i runga i te meka e te mara hiko (konei ingoa tetahi - mara) rerekē te kawe ia o te mata o te apa Semiconductor i te rohe ki te uruhanga. whakamahia ana tēnei taonga i roto i iahiko hiko mō te ngā take. Mos transistor He he hanganga e taea ki te raro i te ātete i waenganui i te waikeri me te puna i raro i te mana o te tohu mana nui ki te kore.

He rerekē i pourua "whakataetae" ona āhuatanga. Ko ratou te hunga e whakatau i te hōkai o tona tono.

• tutuki mahi High e miniaturizing te karaihe iho me ona āhuatanga ahurei. he tika ki te mau fifi i roto i te hanga ahumahi tenei. I tēnei wā, kei te hua tioata ki te kuwaha 0,06 micron.
• He te puritanga whakawhiti iti āhei enei whakaaro ki te mahi i roto i takatakanga auau tiketike. Hei tauira, he LSI me ratou whakamahi kua pai whakamahia i roto i te kōrero pūkoro.
• Tata kore ātete, e kua he MOSFET i roto i te āhua tuwhera, ka taea te whakamahi i te reira rite taviri hiko. Ka taea e ratou te mahi i roto i iahiko mō te whakaputa tohu auau tiketike mō te tūhonoa huānga pērā i amplifiers whakahaere ranei.
• pūrere mano o tenei momo kua pai whakamahia i roto i ngā kōwae mana, a taea te whakauru i roto i te ara iahiko arataki. He tauira pai o ratou whakamahi ai hei te inverter.

A, no te hoahoa me te mahi ki enei āhuatanga he tika ki te whakaaro te tahi mau āhuatanga. He tairongo ki overvoltage ka whakataka ngāwari kore MOSFETs. Ko te iahiko hiko whakamahia nuitia nui-tere te p Schottky mō te whakaene i te pini ngaohiko whakamuri, e puta i roto i whakawhiti.

He āhua nui opuaraa mo te whakamahi o ēnei whakaaro. Te whakapai ake i te hangarau o ratou hanga he i runga i ngā huarahi ki te whakaiti i te karaihe (marumaru tauine). Āta puta whakaaro e e taea ki te whakahaere i motors atu kaha.
