Ama-semiconductors:
Imboni ye-semiconductor ilandela umthetho wezimboni "wesizukulwane esisodwa sobuchwepheshe, isizukulwane esisodwa senqubo, nesizukulwane esisodwa semishini", futhi ukuthuthukiswa nokuphindaphinda kwemishini ye-semiconductor kuncike kakhulu ekuthuthukisweni kwezobuchwepheshe kwezingxenye ezinembayo. Phakathi kwazo, izingxenye ze-ceramic ezinembayo ziyizinto ezimele kakhulu zezingxenye ze-semiconductor ezinembayo, ezinezinhlelo zokusebenza ezibalulekile ochungechungeni lwezixhumanisi ezinkulu zokukhiqiza i-semiconductor njengokufakwa komhwamuko wamakhemikhali, ukufakwa komhwamuko obonakalayo, ukufakwa kwe-ion, nokushumeka. Okufana namabheringi, ama-rails okuqondisa, ama-linings, ama-chucks e-electrostatic, izingalo zokubamba ngomshini, njll. Ikakhulukazi ngaphakathi kwendawo yokusebenza, idlala indima yokusekela, ukuvikela, nokuphambukisa.
Kusukela ngo-2023, i-Netherlands ne-Japan nazo zikhiphe ngokulandelanayo imithethonqubo emisha noma iziyalezo zohwebo lwangaphandle mayelana nokulawula, zengeza imithetho yelayisense yokuthekelisa yemishini ye-semiconductor okuhlanganisa nemishini ye-lithography, kanye nokuthambekela kokulwa nokuqiniswa kwembulunga yonke kwe-semiconductor kuye kwavela kancane kancane. Ukubaluleka kokulawula okuzimele kwe-supply chain sekuya ngokuya kugqama. Njengoba zibhekene nesidingo sokwenziwa kwasendaweni kwezingxenye zemishini ye-semiconductor, izinkampani zasekhaya zigqugquzela ukuthuthukiswa kwezimboni ngentshiseko. I-Zhongci Electronics ibone ukwenziwa kwasendaweni kwezingxenye ezinemba zobuchwepheshe obuphezulu ezifana namapuleti okushisa nama-chucks e-electrostatic, ukuxazulula inkinga “yebhodlela” yemboni yemishini ye-semiconductor yasekhaya; I-Dezhi New Materials, umphakeli ohamba phambili wasekhaya wezisekelo ze-graphite eziboshwe nge-SiC nezindandatho ze-SiC etching, iqede ngempumelelo uxhaso lwezimali lwama-yuan ayizigidi eziyi-100, njll..
I-high-conductivity ye-silicon nitride ceramic substrates:
Ama-substrates e-Silicon nitride ceramic asetshenziswa kakhulu kumayunithi kagesi, kumadivayisi we-semiconductor kanye nama-inverter ezimoto zikagesi ezihlanzekile (EVs) kanye nezimoto zikagesi eziyi-hybrid (ama-HEV), futhi zinamathuba amakhulu emakethe kanye namathemba okusebenza.
Njengamanje, i-thermal conductivity ephezulu ye-silicon nitride ceramic substrate materials yezinhlelo zokusebenza zentengiso idinga ukuhanjiswa okushisayo ≥85 W/(m·K), amandla okugoba ≥650MPa, nokuqina kokuphuka 5~7MPa·m1/2. Izinkampani ezinekhono ngempela lokukhiqiza ngobuningi ama-thermal conductivity high silicon nitride ceramic substrates ikakhulukazi i-Toshiba Group, i-Hitachi Metals, i-Japan Electric Chemical, i-Japan Maruwa kanye ne-Japan Fine Ceramics.
Ucwaningo lwasekhaya ngezinto zokwakha ze-silicon nitride ceramic substrate nazo zenze inqubekelaphambili ethile. I-thermal conductivity ye-silicon nitride ceramic substrate elungiswe inqubo yokusakazwa kwetheyiphu ye-Beijing Branch yase-Sinoma High-Tech Nitride Ceramics Co., Ltd. ingu-100 W/(m·K); I-Beijing Sinoma Artificial Crystal Research Institute Co., Ltd. ilungiselele ngempumelelo i-silicon nitride ceramic substrate enamandla okugoba angu-700-800MPa, ukuqina kokuphuka ≥8MPa·m1/2, kanye ne-thermal conductivity ≥80W/(m·K) ngokuthuthukisa indlela ye-sintering kanye nenqubo.
