| Zusammenfassung: | A pin for a graphite boat is provided. The pin includes a main portion, a neck portion, and a head portion. The main portion is assembled to the graphite boat and carries a chip. The neck portion is connected to the main portion for being leaned against by the edge of the chip. The head portion is connected to the neck portion for limiting the movement of the chip away from the main portion. When the edge of the chip leans against the neck portion, the head portion has a masking zone relative to the chip. A ratio between the area of the masking zone and that of the chip is 0.0001 - 0.0004. |
