1. Prepare CVD-SiC block source: First, you need to prepare a H\u00f8j renhed CVD Solid Sic Bulk<\/a> source, which is usually of high purity and high density. This can be prepared by chemical vapor deposition (CVD) method under appropriate reaction conditions.<\/p>\n
2. Substratforberedelse: V\u00e6lg et passende underlag som underlag til SIC -enkeltkrystallv\u00e6kst. Almindeligt anvendte substratmaterialer inkluderer siliciumcarbid, siliciumnitrid osv., Som har et godt match med den voksende SIC -enkeltkrystall.<\/p>\n
3. Opvarmning og sublimering: Placer CVD-SIC-blokkilden og substratet i en h\u00f8je temperaturovn og giver passende sublimeringsbetingelser. Sublimering betyder, at blokkilden ved h\u00f8j temperatur \u00e6ndrer sig direkte fra fast til damptilstand og derefter kondenseres p\u00e5 substratoverfladen for at danne en enkelt krystal.<\/p>\n
4. Temperaturkontrol: Under sublimeringsprocessen skal temperaturgradienten og temperaturfordelingen kontrolleres n\u00f8jagtigt for at fremme sublimeringen af blokkilden og v\u00e6ksten af enkeltkrystaller. Passende temperaturkontrol kan opn\u00e5 ideel krystalkvalitet og v\u00e6kstrate.<\/p>\n
5. Atmosf\u00e6rekontrol: Under sublimeringsprocessen skal reaktionsatmosf\u00e6ren ogs\u00e5 kontrolleres. Inert gas med h\u00f8j renhed (s\u00e5som argon) bruges normalt som b\u00e6rergas til at opretholde passende tryk og renhed og forhindre forurening ved urenheder.<\/p>\n
6. Enkelt krystalv\u00e6kst: CVD-SIC-blokkilden gennemg\u00e5r en dampfaseovergang under sublimeringsprocessen og recondenses p\u00e5 substratoverfladen for at danne en enkelt krystalstruktur. Hurtig v\u00e6kst af SIC -enkeltkrystaller kan opn\u00e5s gennem passende sublimeringsbetingelser og temperaturgradientkontrol.<\/p>\n
