摘要:
Systems and methods to protect a mask from being contaminated by airborne particles are described. The systems and methods include providing a reticle secured in a two-part cover. The two part cover includes a removable protection device used to protect the reticle from contaminants. The cover can be held inside a pod or box that can be used to transport the cover through a lithography system from an atmospheric section to a vacuum section. While in the vacuum section, the removable cover can be moved during an exposure process during which a pattern on the reticle can be formed on a wafer.

A position measurement device measures the position of a position measurement mark formed on the lower surface of a reticle, thereby measuring the position of the reticle. A position measurement device measures the position of the position measurement mark formed on the lower surface of a lower lid, thereby measuring the position of the lower lid. The relative displacement of the reticle and lower lid is known when the position of the reticle and the position of the lower lid are known. Therefore, when the lower lid having the reticle loaded thereon is carried with a carrying device and set in an exposure device, the stop position of the lower lid is determined by taking this displacement into account. As a result, the reticle can be correctly set in the exposure device.

Improvements in a semiconductor wafer container including improvements in side protection to the wafers, improved cover design to minimize rotation, a simplified top cover orientation mechanism and an improved bottom holding mechanism for automation. The side protection to the wafers is with multiple staggered inner and outer walls. The improved cover design improves alignment of the top and bottom housings and minimizes rotation of the housings in transit or motion. The housings have a recessed tab ramp feature with bi-directional locking that also increases the rigidity of the containment device when the two housings are assembled. The improved bottom holding mechanism for automation is an integrated feature that is molded into the bottom housing and not assembled in a secondary operation. The molded integration reduces tolerance errors that are present in assembling multiple pieces and joining multiple pieces.

The housings have a recessed tab ramp feature with bi-directional locking that also increases the rigidity of the containment device when the two housings are assembled. The latching mechanism is located in a protective latch well that minimizes accidental opening of the latch(s). The improved bottom holding mechanism for automation is an integrated feature that is molded into the bottom housing and not assembled in a secondary operation.

A clean container having an elastic positioning structure includes a support element and a back positioning element on a base. A cover is disposed for covering the base, and a positioning part is disposed between the cover and the base, which has two elastic arms extended laterally, and each elastic arm extends with a pushing surface respectively. When a plate of brittle material is placed on the base, and the cover is closed, the pushing surfaces are elastically pressed against and push the plate respectively, so that the plate moves backwards and presses against the back positioning element. Therefore, the plate is prevented from being damaged. Additionally, the base, the cover, and the positioning part are made of a conductive material, so that the electrostatic charges for the plate is conducted out of the clean container, and has a protective function of an electrostatic discharge.

摘要:
The present invention provides a storage apparatus for storing a semiconductor element or a reticle and having a filter therein. The storage apparatus includes a first cover and a second cover, which are assembled together to form an inner space therebetween for accommodating a reticle or a semiconductor element. The second cover of the storage apparatus is composed of a body and a plate. Further, the second cover includes at least one aperture for communicating the inner space and an outer of the storage apparatus. The plate has a corresponding portion positionally corresponding to the aperture of the body. The filter is sandwiched between the body and the plate and covered the aperture so that when the air passes through the aperture of the body, the filter can filter and rid the air of impurities.

A position measurement device 29 measures the position of a position measurement mark 26 formed on the lower surface of a reticle 1, thereby measuring the position of the reticle 1. A position measurement device 30 measures the position of the position measurement mark 27 formed on the lower surface of a lower lid 2b, thereby measuring the position of the lower lid 2b. The relative displacement of the reticle 1 and lower lid 2b is known when the position of the reticle 1 and the position of the lower lid 2b are known. Therefore, when the lower lid 2b having the reticle 1 loaded thereon is carried with a carrying device and set in an exposure device, the stop position of the lower lid 2b is determined by taking this displacement into account. As a result, the reticle 1 can be correctly set in the exposure device.
