MEMBER ARRANGED IN WAFER STORING CONTAINER AND METHOD FOR MANUFACTURING THE MEMBER

摘要

Provided is a member, which does not contaminate a wafer by generating a sulfur gas, has a good quality by being well formed by injection molding process and is to be arranged in a wafer storing container. A member (1) is to be arranged in a container (2) for storing a wafer (3), and the member (1) to be arranged in the container is formed by injection-molding polybutylene terephthalate (PBT) resin. The PBT resin has a weight-average molecular weight (Mw) of 15,000-20,000, and the member (1) to be arranged in the wafer storing container is formed by injection molding to have the weight of sulfur in a sulfur secondary antioxidant added to the PBT resin 0.1% or less to the weight of the PBT resin.
