Chemical Inertness: <\/strong>Silicon Carbide SiC Wafers is chemically inert, making it resistant to corrosion and suitable for harsh environments.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Production Of Silicon Carbide SiC Wafers<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The production of SiC bulk wafer primarily employs two methods: Physical Vapor Transport (PVT) and Chemical Vapor Deposition (CVD). In the PVT method, the process begins with placing a seed crystal of SiC inside a high-temperature furnace. A source material, typically composed of silicon or carbon, is then heated until it vaporizes. This vapor is carried by a carrier gas, usually argon, and subsequently deposited on the seed crystal. This process results in the formation of a single crystal SiC layer. Conversely, the CVD method involves depositing a SiC layer on a substrate through the reaction of a gas mixture containing silicon and carbon precursors at elevated temperatures.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img  title=\"\" fetchpriority=\"high\" decoding=\"async\" width=\"500\" height=\"500\" src=\"https:\/\/www.sapphire-glass.net\/wp-content\/uploads\/2024\/07\/\u5fae\u4fe1\u56fe\u7247_20240624163554.jpg\"  alt=\"_20240624163554 Silicon Carbide SiC Wafers\"  class=\"wp-image-687\" srcset=\"https:\/\/www.sapphire-glass.net\/wp-content\/uploads\/2024\/07\/\u5fae\u4fe1\u56fe\u7247_20240624163554.jpg 500w, https:\/\/www.sapphire-glass.net\/wp-content\/uploads\/2024\/07\/\u5fae\u4fe1\u56fe\u7247_20240624163554-300x300.jpg 300w, https:\/\/www.sapphire-glass.net\/wp-content\/uploads\/2024\/07\/\u5fae\u4fe1\u56fe\u7247_20240624163554-150x150.jpg 150w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-white-color has-vivid-green-cyan-background-color has-text-color has-background has-link-color has-medium-font-size wp-elements-754446e884185da1a95df6adf0f94eb9 wp-block-paragraph\"><strong>Production of <strong>Silicon Carbide SiC Wafers<\/strong><\/strong><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>1.

These wafers are then polished to achieve a high degree of flatness and smoothness, essential for further semiconductor layer growth. The polished SiC bulk waferserve as a robust platform for the deposition of additional semiconductor layers. These layers can be precisely doped with impurities to create p-type and n-type regions, which are fundamental for the fabrication of various semiconductor devices.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Product Parameter Of Silicon Carbide SiC Wafers<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>Growth Method<\/strong><\/td><td colspan=\"2\">Physical Vapor Transport<\/td><\/tr><tr><td colspan=\"3\"><strong>Physical Properties<\/strong><\/td><\/tr><tr><td>Structure<\/td><td colspan=\"2\">Hexagonal, Single Crystal<\/td><\/tr><tr><td>Diameter<\/td><td colspan=\"2\">Up to 150mm, 200mm<\/td><\/tr><tr><td>Thickness<\/td><td colspan=\"2\">350\u00b5m (n-type, 3\u2033 SI), 500\u00b5m (SI)<\/td><\/tr><tr><td>Grades<\/td><td colspan=\"2\">Prime, Development, Mechanical<\/td><\/tr><tr><td colspan=\"3\"><strong>Thermal Properties<\/strong><\/td><\/tr><tr><td>Thermal Conductivity<\/td><td colspan=\"2\">370 (W\/mK) at Room Temperature<\/td><\/tr><tr><td>Thermal Expansion Coefficient<\/td><td colspan=\"2\">4.5 (10<sup>-6<\/sup>K<sup>-1<\/sup>)<\/td><\/tr><tr><td>Specific Heat (25\u2070C)<\/td><td colspan=\"2\">0.71 (J g<sup>-1<\/sup>&nbsp;K<sup>-1<\/sup>)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td colspan=\"3\"><strong>Additional Key Properties of II-VI SiC Substrates (typical values*)<\/strong><\/td><\/tr><tr><td>Parameter<\/td><td>N-type<\/td><td>Semi-insulating<\/td><\/tr><tr><td>Polytype<\/td><td>4H<\/td><td>4H, 6H<\/td><\/tr><tr><td>Dopant<\/td><td>Nitrogen<\/td><td>Vanadium<\/td><\/tr><tr><td>Resistivity<\/td><td>~0.02 Ohm-cm<\/td><td>&gt; 1\u221910<sup>11<\/sup>&nbsp;Ohm-cm<\/td><\/tr><tr><td>Orientation<\/td><td>4\u00b0 off-axis<\/td><td>On-axis<\/td><\/tr><tr><td>FWHM<\/td><td>&lt; 20 arc-sec<\/td><td>&lt; 25 arc-sec<\/td><\/tr><tr><td>Roughness, Ra**<\/td><td>&lt; 5 \u00c5<\/td><td>&lt; 5 \u00c5<\/td><\/tr><tr><td>Dislocation density<\/td><td>~5\u221910<sup>3<\/sup>&nbsp;cm<sup>-2<\/sup><\/td><td>&lt; 1\u221910<sup>4<\/sup>&nbsp;cm<sup>-2<\/sup><\/td><\/tr><tr><td>Micropipe density<\/td><td>&lt; 0.1 cm<sup>-2<\/sup><\/td><td>&lt; 0.1 cm<sup>-2<\/sup><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Product Application Of Silicon Carbide SiC Wafers<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/www.sapphire-glass.net\/en\/customer-orders-3-inch-silicon-carbide-sic-wafers\/\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-red-color\">Silicon Carbide (SiC) wafers <\/mark><\/a><\/strong>are increasingly being utilized across a wide range of applications, particularly in areas that demand high performance under extreme conditions.

have distinct properties and applications. Monocrystalline wafers are prized for their high purity and efficiency in electronics and solar cells. Polycrystalline wafers offer a cost-effective solution for photovoltaic applications, albeit with lower efficiency. Silicon-on-insulator wafers provide significant advantages in advanced microelectronics and MEMS devices due to their superior electrical isolation and performance characteristics. Each type of wafer is tailored to meet specific needs within the semiconductor industry.<\/p>","protected":false},"excerpt":{"rendered":"<p>Silicon Carbide SiC wafers are a crucial type of semiconductor material extensively utilized in the manufacturing of electronic and optoelectronic devices that demand high-temperature endurance, high-voltage stability, and high-frequency performance. <\/p>","protected":false},"author":1,"featured_media":610,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_joinchat":[],"footnotes":""},"categories":[3,5],"tags":[],"class_list":["post-672","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-products-catelog","category-sic-wafer-substrate"],"acf":[],"views":3739,"_links":{"self":[{"href":"https:\/\/www.sapphire-glass.net\/en\/wp-json\/wp\/v2\/posts\/672","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sapphire-glass.net\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.sapphire-glass.net\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.sapphire-glass.net\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sapphire-glass.net\/en\/wp-json\/wp\/v2\/comments?post=672"}],"version-history":[{"count":63,"href":"https:\/\/www.sapphire-glass.net\/en\/wp-json\/wp\/v2\/posts\/672\/revisions"}],"predecessor-version":[{"id":824,"href":"https:\/\/www.sapphire-glass.net\/en\/wp-json\/wp\/v2\/posts\/672\/revisions\/824"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.sapphire-glass.net\/en\/wp-json\/wp\/v2\/media\/610"}],"wp:attachment":[{"href":"https:\/\/www.sapphire-glass.net\/en\/wp-json\/wp\/v2\/media?parent=672"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sapphire-glass.net\/en\/wp-json\/wp\/v2\/categories?post=672"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sapphire-glass.net\/en\/wp-json\/wp\/v2\/tags?post=672"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
