Story<\/h2>\n\t<div class=\"container-fluid\">\n\t\t<h4 class=\"cap-bdrleft\">The roots of our mask blanks lie in material development utilizing our in-house vacuum equipment.<\/h4>\n\t\t<p>ULVAC was conducting material development using in-house-developed vacuum equipment in the late 1960s. This initiative was encouraged and directed by Chikara Hayashi, the vice president at the time.<\/p>\n\t\t<p>The result was a hybrid thin film of chrome cermet (a type of composite metal material containing chrome oxide), which was applied to sunglasses to block direct sunlight. However, as there was no clear idea of how to utilize its properties beyond sunglasses, it was never commercialized and was left abandoned in a corner of the exhibition room.<\/p>\n\t\t<p>One day, a manager from a major electronics manufacturer saw the sunglasses and remarked, \"Since the chrome film blocks ultraviolet rays, it might be useful as a mask for IC circuits.\" This single comment sparked the person in charge's curiosity and investigative spirit.<\/p>\n\t\t<p>Without delay, our engineers investigated the status of IC circuit masks and discovered that the emulsion method using photographic plates was being utilized.<\/p>\n\t\t<h4 class=\"cap-bdrleft m-t-3\">Development of the world's first mask blanks, expanding into the global market<\/h4>\n\t\t<p>The advancement of semiconductor integrated circuits (ICs) cannot be discussed without mentioning the miniaturization of circuit patterns enabled by photolithography technology. At the core of photolithography technology is photomask technology. Furthermore, the base material for a photomask is called a mask blank. As the word 'blank' suggests, a mask blank refers to the original plate before the circuit pattern is created. These mask blanks are currently used not only for semiconductor ICs but also for FPDs (Flat Panel Displays). Mask blanks can be broadly classified into two types based on their materials: hard masks and emulsion masks. However, at that time, hard masks had not yet been put into practical use, and emulsion masks were the mainstream. Emulsion masks were made by coating a substrate, such as glass, with a silver halide emulsion, similar to that used in photographic plates. The drawback of this type was that the coated surface was not transparent, making it unsuitable for alignment when stacking multiple layers. As the trend toward higher integration continued at the time, there was an increasing demand for mask blanks that allowed for more precise work. <\/p>\n\t\t<p>The conclusion ULVAC reached was: \"Since the light source used in IC manufacturing processes is ultraviolet, allowing visible light (can be detectabl by the human eyes) to pass through poses no issue. In other words, if we could create a film that transmits visible light but blocks only ultraviolet light, it would enable alignment tasks to be performed while visually verifying positioning. By using the chrome film we developed, we have created an innovative solution that fully overcomes this drawback.<\/p>\n\t\t<p>This led to the completion of the chrome film hard mask blank in 1970. Initially named the 'ST Mask', it was also the world's first achievement of its kind. 'ST' stands for 'See Through', literally representing the unique feature of the chrome film, which blocks ultraviolet light while allowing visible light to pass through.<\/p>\n\t\t<h5 class=\"m-t-3\">The ULVAC Coating Group contributes to <span class=\"marker-sub2\">'Cutting-Edge Industries'<\/span> around the world through our products.<\/h5>\n\t\t<div class=\"text-center m-t-2\"><img decoding=\"async\" class=\"img-fluid\" src=\"https:\/\/www.ulcoat.co.jp\/en\/wp-content\/themes\/ulcoat2025\/images\/product_info\/img_01.png\"><\/div>\n    <\/div>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Features of ULVAC Coating Corporation (ULCOAT) Mask Blanks &#xFF11;By applying inline-type sputtering depositi [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-17","page","type-page","status-publish","hentry"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.ulcoat.co.jp\/en\/wp-json\/wp\/v2\/pages\/17","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ulcoat.co.jp\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.ulcoat.co.jp\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.ulcoat.co.jp\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ulcoat.co.jp\/en\/wp-json\/wp\/v2\/comments?post=17"}],"version-history":[{"count":167,"href":"https:\/\/www.ulcoat.co.jp\/en\/wp-json\/wp\/v2\/pages\/17\/revisions"}],"predecessor-version":[{"id":1042,"href":"https:\/\/www.ulcoat.co.jp\/en\/wp-json\/wp\/v2\/pages\/17\/revisions\/1042"}],"wp:attachment":[{"href":"https:\/\/www.ulcoat.co.jp\/en\/wp-json\/wp\/v2\/media?parent=17"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
