Molecular Beam Epitaxy and Liquid Nitrogen Circulation System in Semiconductor and Chip Industry

He poto mo te Epitaxy Beam Molecular (MBE)

I whakawhanakehia te hangarau o te Molecular Beam Epitaxy (MBE) i te tekau tau atu i 1950 ki te whakarite i nga rawa kiriata angiangi semiconductor ma te whakamahi i te hangarau whakaetonga korehau. Na te whanaketanga o te hangarau korehau ultra-tiketike, kua horahia te tono o te hangarau ki te mara o te pūtaiao semiconductor.

Ko te hihiri o te rangahau rauemi semiconductor ko te tono mo nga taputapu hou, ka pai ake te mahi o te punaha. Ka huri, ka whakaputahia e te hangarau rauemi hou nga taputapu hou me nga hangarau hou. Ko te epitaxy kurupae rapoi (MBE) he hangarau korehau teitei mo te tipu o te paparanga epitaxial (te nuinga o te wa whakangao). Ka whakamahia e ia te kurupae wera o nga ngota puna, ngota ngota ranei e pa ana ki te tïpako karaihe kotahi. Ko nga ahuatanga korehau tino teitei o te mahi ka taea te whakarewatanga i roto i te waahi me te tipu o nga rawa whakaraerae i runga i nga mata semiconductor katahi ano ka tupu, ka hua mai he atanga kore poke.

Hangarau MBE

I mahia te epitaxy kurupae rapoi i roto i te korehau teitei, te korehau tino teitei ranei (1 x 10-8Pa) taiao. Ko te mea tino nui o te epitaxy kurupae rapoi ko tona reiti waiparatanga iti, ko te tikanga ka taea e te kiriata te tipu epitaxial i te tere o te iti iho i te 3000 nm ia haora. Ko te iti o te reiti waipara e hiahia ana kia nui te korehau kia eke ki te taumata o te ma ki etahi atu tikanga tuku.

Ki te whakatutuki i te korehau tino teitei e whakaahuatia ana i runga ake nei, ko te taputapu MBE (Knudsen cell) he paparanga whakamatao, a me mau tonu te taiao korehau tino teitei o te ruuma tipu ma te whakamahi i te punaha tohanga hauota wai. Ko te hauota wai ka whakamatao i te pāmahana o roto o te taputapu ki te 77 Kelvin (−196 °C). Ka taea e te taiao pāmahana iti te whakaiti ake i te ihirangi o nga poke i roto i te korehau me te whakarato i nga tikanga pai ake mo te tukunga o nga kiriata kikokore. Na reira, ka hiahiatia he punaha tohanga hauota hauota wai mo nga taputapu MBE ki te whakarato tonu me te pumau o te -196 °C hauota wai.

Te Pūnaha Whakamao Hauota Wai

Ko te nuinga o nga punaha tohanga hauota wai hauota, kei roto,

● tank cryogenic

● matua me te manga korehau jacketed putorino / korehau jacketed ngongo ngongo

● MBE whakawehe wāhanga motuhake me te korehau koti ngongo putorino

● momo maru maru maru takirere

● arai hau-wai

● tātari koti korehau

● pūnaha papu korehau hihiri

● Te whakamatao o mua me te horoi i te punaha whakamahana

Kua kite a HL Cryogenic Equipment Company i te hiahia o te punaha whakamahana hauota wai MBE, kua whakaritea te tuara hangarau kia pai ai te whakawhanake i tetahi punaha whakahiato hauota wai MBE motuhake mo te hangarau MBE me te huinga katoa o te whakamaarama korehau.edpūnaha paipa, kua whakamahia i roto i te maha o nga umanga, whare wananga me nga whare rangahau.
