Abstract
Description
金属のボンドまたはセラミックのボンドを含む砥石によって板状体の外周の少なくとも一部を研削する研削工程と、
前記板状体の前記砥石によって研削された部分を弾性砥石によって面取りする面取り工程とを有し、
前記砥石は、円柱状または円錐台状であり、外周に板状体を研削する砥粒面を有し、該砥粒面に研削溝を有しない、板状体の加工方法が提供される。
図1は、本発明の第1実施形態による加工前の積層体を示す側面図である。加工前の積層体10は、例えば図1に示すようにガラス基板11およびガラス基板11と剥離可能に結合する補強板12を備える。積層体10は、後述の加工方法で加工された後、製品の製造に用いられる。1つの製品の製造に、複数の積層体10が用いられてもよい。製品としては、例えば画像表示装置、太陽電池、薄膜2次電池などの電子デバイスが挙げられる。画像表示装置としては、例えば液晶ディスプレイ、プラズマディスプレイ、有機ELディスプレイなどが挙げられる。
第2実施形態の積層体の加工方法は、砥石が円錐台状である点で、上記第1実施形態の積層体の加工方法とは異なる。以下、相違点を中心に説明する。
