  • Patent number: 11581209
    Abstract: Environmental control material holders can retain environmental control material within wafer carriers, allowing the environmental control material to protect wafers from moisture while also securing the environmental control material. The environmental control material holders may include a baseplate and tabs defining spaces to hold environmental control material, and can be configured to engage a handle of a wafer cassette. The environmental control material holders may retain one or more environmental control materials. Additionally, the environmental control material holders can be configured to also retain a humidity indicator.
    Type: Grant

  • Publication number: 20220230900
    Abstract: A handle for a wafer carrier that includes an insertable member configured to be inserted into an aperture of the wafer carrier, and a locking mechanism moveable relative to the insertable member. A tab of the insertable member retains the insertable member in the aperture when in an engaged state. When in a locked state, the locking mechanism maintains the tab in the engaged state and a flexible member of the locking mechanism is positioned to maintain the locking mechanism in the locked state. A wafer carrier includes the detachable handle and the locking mechanism.

  • Patent number: 10593577
    Abstract: A reticle container for containing a reticle including a base plate having one or more windows. Each of the windows can include mounting recess having a recess sidewall including an undercut defined therein. A transparent substrate can be disposed in the mounting recess and is retained therein by a retention member having an arcuate portion extending between a first end portion and a second end portion. At least the first end portion of the retention member can be positioned in the undercut defined in the recess sidewall such that the arcuate portion of the retention member contacts the transparent substrate to retain the transparent substrate in the mounting recess.

  • Patent number: 10217655
    Abstract: A front opening wafer container has a container portion and a door sized to close an open front of the container portion. The container portion has shelves for holding wafers defining a seating position and has forward and rearward wafer supports to suspend wafers therebetween in a transport position above the seating position. Shock condition cushion portions are arranged adjacent the transport position for protecting the wafers during a shock condition. The wafers may be bonded wafers having a thinned wafer side and a carrier substrate side. Wafer engagement pads and finger members extend in opposing directions from a central strip on the door providing a balance wafer engagement. When closing the door, a primary wafer support portion engages the wafers first and a secondary elastomeric wafer support engages the wafer secondly.
