KUTSANANGURWA KWENYAYA:
Si / Al alloys emagetsi mapakeji anonyanya kureva eutectic alloy zvinhu zvine silicon zvemukati me11% kusvika 70%. Kuwanda kwayo kwakaderera, iko kuganisana kwekuwedzera kwekushisa kunogona kuenzaniswa kune chip uye substrate, uye kugona kwayo kubvisa kupisa kwakanyanya. Kugadzirwa kwayo kwemuchina zvakare kwakakodzera. Nekuda kweizvozvo, maAl / alloys ane mukana wakakura muindasitiri yekupakata yemagetsi.

ZVIKURU ZVINOKOSHA:
• Kutsanya kupisa kupisa uye kwakanyanya kupisa kupisa kunogona kugadzirisa matambudziko ekupisa ekupisa anowanikwa mukuvandudzwa kwemagetsi emagetsi.
• Iyo coefficient yekupisa kwekuwedzera inodzora, izvo zvinoita kuti zvikwanise kuenzanisa neiyo yechip, kudzivirira zvakanyanya kupisa kwekushushikana kunogona kukonzeresa kukundikana kwechigadzirwa.

KUTSANANGURWA KWENYAYA:
Aluminium nitride zvedongo ndeyehunyanzvi zvedongo zvinhu. Iyo ine yakanakisa yekupisa, yemagetsi uye yemagetsi zvivakwa, senge yakakwira magetsi conduction, diki hama dielectric nguva dzose, mutsetse wekuwedzera coefficient inoenderana nesilicon, yakanakisa yemagetsi kuputira, uye yakaderera density. Iyo haina-chepfu uye yakasimba. Nekuvandudzwa kwakakura kwema microelectronic zvishandiso, aluminium nitride ceramics sechinhu chepasi kana cheimba yepakeji, yave kuwedzera kufarirwa. Iyo inovimbisa yepamusoro-simba rakabatanidzwa redunhu substrate uye yekupakisha zvinhu.
