  • Publication number: 20130089280
    Abstract: A sealable plastic bag has a first panel and a second panel. The first panel and second panel are joined along three edges to define a bag interior and an opening to permit access to the bag interior. A permanent sealing structure is configured to permanently seal the first and second panels to close the opening and prevent access to the bag interior. A release liner strip overlies the permanent sealing structure to prevent the permanent sealing structure from sealing the first and second panels until activation by a user. A resealable sealing structure is configured to repeatedly and nondestructively seal the first and second panels to close the opening and prevent access to the bag interior.

  • Publication number: 20130077894
    Abstract: A sealable plastic bag has a first panel and a second panel. The first and second panels are joined to each other along three edges to define a bag interior and an opening permitting access to the bag interior. A resealable sealing structure extends continuously between the first and second side edges of at least one of the panels and is configured to repeatedly and nondestructively seal and unseal the first and second panels to close and open the bag interior. A secondary sealing structure extends continuously between the first and second side edges of both of the panels below the resealable sealing structure but spaced toward the top edges of the panels. The secondary sealing structure is also configured to repeatedly and nondestructively seal and unseal the first and second panels together to close and open the bag interior.

  • Patent number: 8094924
    Abstract: An apparatus comprises an imaging unit to image a wafer to be reviewed, wherein imaging unit is the modified SORIL column. The modified SORIL column includes a focusing sub-system to do micro-focusing due to a wafer surface topology, wherein the focusing sub-system verifies the position of a grating image reflecting from the wafer surface to adjust the focus; and a surface charge control to regulate the charge accumulation due to electron irradiation during the review process, wherein the gaseous molecules are injected under a flood gun beam rather than under a primary beam. The modified SORIL column further includes a storage unit for storing wafer design database; and a host computer to manage defect locating, defect sampling, and defect classifying, wherein the host computer and storage unit are linked by high speed network.
