Li-semiconductors:
Indasteri ea semiconductor e latela molao oa indasteri oa "moloko o le mong oa thekenoloji, moloko o le mong oa ts'ebetso, le moloko o le mong oa thepa", 'me ho ntlafatsa le ho pheta-pheta ha lisebelisoa tsa semiconductor ho itšetlehile haholo ka katleho ea theknoloji ea likarolo tse nepahetseng. Har'a tsona, likarolo tsa ceramic tse nepahetseng ke lisebelisoa tse emelang ka ho fetesisa tsa semiconductor, tse nang le ts'ebeliso ea bohlokoa letotong la lihokelo tse kholo tsa tlhahiso ea semiconductor joalo ka deposition ea mouoane oa lik'hemik'hale, ho beha mouoane oa 'mele, ho kenngoa ha ion le etching. Tse kang dibering, rails tataiso, linings, chucks electrostatic, mechine ho tšoara matsoho, joalo-joalo Haholo-holo ka hare ho cavity thepa, e phetha karolo ea ho tšehetsa, tšireletso le khelosoa.
Ho tloha ka 2023, Netherlands le Japane le tsona li fane ka melaoana e mecha kapa melaoana ea khoebo ea kantle ho naha mabapi le taolo ka tatellano, ho eketsa melaoana ea laesense ea kantle ho naha bakeng sa lisebelisoa tsa semiconductor ho kenyeletsoa le mechini ea lithography, mme mokhoa oa semiconductor anti-globalization o hlahile butle butle. Bohlokoa ba taolo e ikemetseng ea ketane ea phepelo e se e totobala haholo. Ka lebaka la tlhoko ea ho aha likarolo tsa lisebelisoa tsa semiconductor sebakeng sa heno, lik'hamphani tsa lapeng li ntse li khothaletsa nts'etsopele ea indasteri ka mafolofolo. Zhongci Electronics e hlokometse ho kenngoa ha likarolo tse nepahetseng tsa theknoloji e phahameng tse kang lipoleiti tse futhumatsang le li-chucks tsa electrostatic, ho rarolla bothata ba "bottleneck" ea indasteri ea thepa ea malapeng ea semiconductor; Dezhi New Materials, morekisi ea ka sehloohong oa lehae oa SiC coated graphite bases le SiC etchingrings, o atlehile ho phethela lichelete tsa li-yuan tse limilione tse 100, joalo-joalo…..
Lisebelisoa tse phahameng tsa silicon nitride ceramic substrates:
Li-substrates tsa silicon nitride ceramic li sebelisoa haholo ho lisebelisoa tsa motlakase, lisebelisoa tsa semiconductor le li-inverters tsa likoloi tse hloekileng tsa motlakase (EVs) le likoloi tsa motlakase tse nyalisitsoeng (HEVs), 'me li na le menyetla e meholo ea mmaraka le menyetla ea ts'ebeliso.
Hajoale, lisebelisoa tse phahameng tsa conductivity tsa silicon nitride ceramic substrate bakeng sa lits'ebetso tsa khoebo li hloka conductivity ea mocheso ≥85 W/(m·K), matla a ho kobeha ≥650MPa, le boima ba fracture 5~7MPa·m1/2. Lik'hamphani tse nang le bokhoni ba ho hlahisa lihlahisoa tse phahameng tsa mocheso oa silicon nitride ceramic substrates haholo-holo ke Toshiba Group, Hitachi Metals, Japan Electric Chemical, Japane Maruwa le Japane Fine Ceramics.
Lipatlisiso tsa malapeng mabapi le lisebelisoa tsa silicon nitride ceramic substrate le tsona li entse tsoelo-pele e itseng. Thermal conductivity ea silicon nitride ceramic substrate e lokisitsoeng ke mokhoa oa ho etsa theipi oa Beijing Lekala la Sinoma High-Tech Nitride Ceramics Co., Ltd. ke 100 W/(m·K); Beijing Sinoma Artificial Crystal Research Institute Co., Ltd. e atlehile ho lokisa silicon nitride ceramic substrate e nang le matla a ho kobeha a 700-800MPa, boima ba fracture ≥8MPa·m1/2, le conductivity ea mocheso ≥80W/(m·K) ka ho ntlafatsa mokgoa le tshebetso ya sintering.
