Container for storing semiconductor device

Abstract

A container for storing semiconductor devices is revealed. The container includes a receiving body and a cover. The receiving body is disposed with at least one fastener and at least one driver therein. The fastener includes a rolling element that is in contact with the driver. When the driver is rotated, it drives the fastener to move in the receiving body. At least one fixing part of the fastener is moved toward at least one fastening part of the cover. The cover is fixed on the receiving body by the fixing part locked in the fastening part. Moreover, friction between the fastener and the driver is minimized by the rolling element which reduces contact area between the fastener and the driver so as to prevent production of contaminants in the container and protect semiconductor devices stored in the container from being polluted. Thus the container is of high cleanness.

AI Technical Summary

Benefits of technology

The present invention relates to a container for storing semiconductor devices. The container includes a fastening member with a fastener and a driver. The fastener is mounted with a rolling element in contact with the driver. This design reduces contact area between the fastener and driver, minimizing friction and preventing production of contaminants. The result is a highly clean container that protects the semiconductor devices during storage. The rolling element moves along with rotation of the driver, effectively reducing friction between the fastener and driver. This ensures that the fastening member works well and the container can be opened and closed smoothly.

Problems solved by technology

But the semiconductor devices with high integrated density are quite sensitive.

Even a bit of contaminants such as particles, dust, organic materials, gas, volatiles, etc result in defects in the semiconductor devices, or static electricity and a short circuit that damage the semiconductor devices.

However, friction occurs between components of fastening members in the container.

Thus not only operation of the fastening member is unstable but the container is not opened or closed smoothly.

Even some contaminants are produced due to the friction and the semiconductor devices stored in the container get polluted.
