MOCVD Susceptor dị elu na-azụta n'ịntanetị na China

Wafer kwesịrị ịgafe ọtụtụ usoro tupu ọ dị njikere maka ojiji na ngwaọrụ eletrọnịkị. Otu usoro dị mkpa bụ silicon epitaxy, nke a na-ebu wafers na graphite susceptors. Ngwongwo na ịdị mma nke ndị na-eche nche nwere mmetụta dị oke mkpa n'ịdị mma nke oyi akwa epitaxial wafer.

Maka usoro ntinye ihe nkiri dị mkpa dị ka epitaxy ma ọ bụ MOCVD, VET na-enye ngwa ngwa graphitee dị ọcha nke a na-eji na-akwado mkpụrụ ma ọ bụ "wafers". Na isi nke usoro a, a na-ebu ụzọ tinye akụrụngwa a, susceptors epitaxy ma ọ bụ nyiwe satịlaịtị maka MOCVD.

● Okpomọkụ dị elu.
● Nnukwu agụụ.
● Iji ihe mgbochi gaseous eme ihe.
● Mmetọ efu, enweghị peeling.
● Iguzogide acid siri ike mgbe a na-arụ ọrụ nhicha

VET Energy bụ ezigbo onye nrụpụta nke ngwaahịa graphite ahaziri iche na silicon carbide nwere mkpuchi maka semiconductor na ụlọ ọrụ fotovoltaic. Anyị oru otu si n'elu ụlọ nnyocha ụlọ ọrụ, nwere ike na-enye ndị ọzọ ọkachamara ihe ngwọta maka gị.

Anyị na-aga n'ihu na-emepụta usoro dị elu iji nye ihe ndị dị elu karị, ma rụọ ọrụ nkà na ụzụ pụrụ iche, nke nwere ike ime ka njikọ dị n'etiti mkpuchi na mkpụrụ ahụ sie ike ma ghara ịdị na-apụ apụ.

2. High ịdị ọcha na thermal uniformity
3. Magburu onwe corrosion eguzogide: acid, alkali, nnu na organic reagents.
4. Elu ike, kọmpat elu, ezigbo ahụ.
5. Ogologo ndụ ọrụ na ihe na-adịgide adịgide
