Description

背板、使用其之濺射靶材及其使用方法 Backplane, sputtering target material using the same, and method of using the same

本發明是有關於一種背板、使用其之濺射靶材及其使用方法。 The invention relates to a backplane, a sputtering target using the same, and a method of using the same.

目前，濺鍍技術(sputtering)係為主要沉積鍍膜技術所使用的方式之一。濺鍍技術一般是在濺鍍腔室中形成電漿，電漿(plasma)會對金屬靶材進行離子轟擊(ion bombardment)，使靶材的金屬原子撞擊出，而形成氣體分子發射到達所要沉積的基材上，氣體分子經過附著、吸附、表面遷徙、成核等濺鍍作用之後，最終在基材上形成具有金屬原子的金屬薄膜。濺鍍技術係廣泛地應用在工業生產和科學研究領域。然而，一般濺射靶材使用焊接製程(bonding)，因此組裝費時、費用較高且使用彈性小。 Currently, sputtering is one of the main methods used to deposit coatings. Sputtering technology generally forms plasma in the sputtering chamber. The plasma bombards the metal target with ion bombardment, causing the metal atoms of the target to strike out, forming gas molecules that emit to the desired deposit. On the substrate, after the gas molecules undergo sputtering such as attachment, adsorption, surface migration, and nucleation, a metal thin film with metal atoms is finally formed on the substrate. Sputtering technology is widely used in industrial production and scientific research. However, the sputtering target generally uses a bonding process, so assembly is time-consuming, expensive, and has low flexibility.
