4 iniha SiC Wafers 6H Semi-Insulating SiC Substrates prime, noiʻi, a me ka papa dummy

4 ʻīniha SiC Wafers 6H Semi-Insulating SiC Substrates prime, noiʻi, a me ka papa dummy kiʻi ʻike ʻia.

ʻO ka wehewehe pōkole:

Hoʻokumu ʻia ka substrate silicon carbide semi-insulated e ka ʻokiʻoki, ka ʻoki ʻana, ka polishing, ka hoʻomaʻemaʻe a me nā ʻenehana hana ʻē aʻe ma hope o ka ulu ʻana o ka semi-insulated silicon carbide crystal. Hoʻoulu ʻia kahi ʻāpana a i ʻole multilayer crystal layer ma luna o ka substrate e hoʻokō i nā koi o ka maikaʻi e like me ka epitaxy, a laila hana ʻia ka mīkini RF microwave ma ka hoʻohui ʻana i ka hoʻolālā kaapuni a me ka hoʻopili. Loaʻa ma ke ʻano he 2inch 3inch 4incgh 6inch 8 iniha ʻenehana, noiʻi a me ka hoʻāʻo ʻana i ka semi-insulated silikon carbide hoʻokahi substrates kristal.

E hoʻouna i ka leka uila iā mākou
