Abstract

La présente invention concerne un dispositif de traçage et un procédé de traçage grâce auxquels la rupture d'un substrat peut être évitée. Le dispositif de traçage est un dispositif de traçage qui amène une pièce de lame et un substrat à se déplacer l'un par rapport à l'autre tout en pressant la pièce de lame contre le substrat pour former une ligne de traçage sur le substrat. Le dispositif de traçage est muni d'une pièce de fixation qui s'incurve et qui fixe le substrat de sorte que la trajectoire du mouvement de la pièce de lame sur le substrat est incurvée.
