Assignee:

Peak Plastic & Metal Products (International) Limited - Tsuen Wan

International Classification:

B65D 85/48

US Classification:

206710, 206454

Abstract:

A wafer container comprising a base and a cover that nest together. The base includes a staggered wall structure composed of inner and outer walls. The staggered wall structure is arranged so that forces from side impacts are absorbed principally by outer wall segments. A rib on the cover restrains the outer wall segments from flexing beyond the inner wall diameter. Reference tabs on the base facilitate alignment of the base to the cover.

Abstract:

A cantilevered clip is provided for holding a stack of at least one tray and tray cover. Stack compressive forces applied by the clip are substantially limited to tray and cover edge portions. The clip has a channel base with left and right side walls attached for restricting movement of a stack in left and right directions. Pressure members are positioned orthogonal to at least one wall. An aperture is located adjacent to each pressure member and partially extends into each wall. Protrusions above the base extend inward towards the walls of the channel for captivating the stack in an upward direction.

International Classification:

B65D 85/30

US Classification:

206710, 206303, 206454

Abstract:

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.

International Classification:

B65D 85/30

US Classification:

206710, 206303, 206454

Abstract:

Improvements in a semiconductor wafer container for reducing movement of semiconductor wafers within a wafer carrier using flexible wall segments, panels or flexible inserts in the base member's main inner containment diameter. These walls allow a vertical containment surface to move and capture the entire stack of wafers rather than a few wafers. The surface that contacts the wafers moves uniformly inward. The wafer stack is secured by reducing or eliminating the gap between the wafer container and the wafer stack. Further improvements include the addition of a ramped engagement surfaces in the top and/or bottom cover that provides mechanical advantage for easier assembly of the top and bottom cover. This design also allows for automated loading and unloading of the wafer stack because once the top cover is removed, the flexible walls spring back outward. Thus providing a small gap in which to freely remove the wafers.

Abstract:

A clip is provided for holding a stack of at least one tray and tray cover. Stack compressive, forces applied by the clip are substantially limited to tray and cover perimeter rail portions. The clip has a channel base with left and right side retaining walls attached for restricting movement of a stack in left and right directions. Left and right rods protrusions above the base extend inward towards the walls of the channel from the left and right side walls respectively for captivating the stack in an upward direction. Spring protrusions extend upward from the base on input and output ends of the channel, and are configured for applying an upward spring force on opposing bottom edge areas of the stack.
