Abstract: A device for maintaining cleanliness in a vacuum environment during semiconductor manufacture in a device storing and transferring wafers into etching and other manufacturing processes includes a transferring chamber storing wafers, a vacuum system to extract particles from the transferring chamber, and a thermoelectric device for temperature control. The vacuum system includes an extracting pipe, the thermoelectric device includes a cooling apparatus to cool the transferring chamber, and a monitoring device to detect particle concentrations in the transferring chamber. The cooling apparatus includes Peltier elements arranged on the extracting pipe to cool and thus cause the descent of fumes and particles towards a low-set extraction area.

Abstract: A chamber apparatus comprises a lower and an upper chamber body, and a gasket member. The lower chamber body defines a receiving region and a first receiving groove. The upper chamber body disposed above the lower chamber body and defines a second receiving groove projectively align to the first receiving groove. The second receiving groove is configured to establish sealing coupling with the lower chamber body so as to form a chamber enclosure region. The gasket member includes a conductive member and an elastomeric member. The conductive member configured to laterally surround the receiving region and respectively fit into the lower chamber body and the upper chamber body. The elastomeric member is protruded from the conductive member and extended toward the receiving region, configured to be compressed by the upper and the lower chamber body so as to seal the chamber enclosure region.

Abstract: Disclosed is a coordination polymer crystal with porous metal-organic frameworks (MOFs), in which, while a crystal state of the coordination polymer crystal is maintained, an additional material selected from the group consisting of an organic compound, a metal cluster, and an organometallic compound is chemically bonded to the coordination polymer crystal. Therefore it is possible easily adsorb and store more guest molecules regardless of a change in an ambient temperature or pressure due to the chemically bonded additional material.
