    In semiconductor manufacturing and precision optics, the choice of substrate material is critical to achieving high device performance and process reliability. Among the most widely used materials are sapphire (Al\u2082O\u2083), quartz (SiO\u2082), and silicon carbide (SiC). While all three offer unique advantages, their properties vary significantly in thermal, mechanical, and chemical aspects, affecting their suitability […]<\/p>\n","protected":false},"author":1,"featured_media":3129,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[65],"tags":[],"class_list":["post-3089","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industry-news"],"_links":{"self":[{"href":"https:\/\/www.sapphiretube.com\/zh\/wp-json\/wp\/v2\/posts\/3089","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sapphiretube.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.sapphiretube.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.sapphiretube.com\/zh\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sapphiretube.com\/zh\/wp-json\/wp\/v2\/comments?post=3089"}],"version-history":[{"count":1,"href":"https:\/\/www.sapphiretube.com\/zh\/wp-json\/wp\/v2\/posts\/3089\/revisions"}],"predecessor-version":[{"id":3092,"href":"https:\/\/www.sapphiretube.com\/zh\/wp-json\/wp\/v2\/posts\/3089\/revisions\/3092"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.sapphiretube.com\/zh\/wp-json\/wp\/v2\/media\/3129"}],"wp:attachment":[{"href":"https:\/\/www.sapphiretube.com\/zh\/wp-json\/wp\/v2\/media?parent=3089"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sapphiretube.com\/zh\/wp-json\/wp\/v2\/categories?post=3089"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sapphiretube.com\/zh\/wp-json\/wp\/v2\/tags?post=3089"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
