Abstract:
(EN)  If the diameter of a glass substrate (1) is Dmm, and the distance from the center position (C1) of a carrier (500) to the center position (C2) of a first holding through hole (520C) of the carrier (500) is rmm, the central position (C2) of the first retaining through hole (520C) of the carrier (500) is provided in a position to satisfy the following relational expression: [(D/4)≤r≤(D/2)].
(FR) Selon l'invention, si le diamètre d'un substrat en verre (1) est Dmm et la distance de la position centrale (C1) d'un support (500) à la position centrale (C2) d'un premier trou traversant de retenue (520C) du support (500) est rmm, la position centrale (C2) du premier trou traversant de retenue (520C) du support (500) est placée en une position qui satisfait l'expression de relation suivante : [(D/4) ≤ r ≤ (D/2)].
(JA)  キャリア(500)の第1貫通保持孔(520C)の中心位置(C2)は、ガラス基板(1)の直径をDmmとし、キャリア(500)の中心位置(C1)から第1貫通保持孔(520C)の中心位置(C2)までの距離をrmmとした場合に、[(D/4)≦r≦(D/2)]の関係式を満足する位置に設けられる。
