  • Patent number: 8026735
    Abstract: A test handler is disclosed in the present invention. The test handler may include a test tray on which a plurality of inserts are arrayed for loading at least one semiconductor device, at least one opening unit for simultaneously opening one part of the plurality of inserts which are arrayed on one part of the test tray, and a test tray transfer apparatus for allowing the opening unit to simultaneously open other parts of the plurality of inserts which are arrayed on another part of the test tray as the test tray is transferred. Therefore, although semiconductor devices to be tested change their sizes, the replaced parts of the test handler are reduced in number, thereby reducing manufacturing cost and replacement work time. The inventive test handler reduces semiconductor devices loading time, reduces jamming, increases teaching efficiency and improves space utilization efficiency. Furthermore, the test handler can be applied to various types of testers.

  • Patent number: 8013620
    Abstract: When a test handler loads semiconductor devices of user trays onto a test tray, the test handler adjusts a front/rear pitch or a right/left pitch between the semiconductor devices, adjusts the right/left pitch or the front/rear pitch, and loads the semiconductor devices. The test handler can sequentially adjust individually the front/rear pitch and the right/left pitch between the semiconductor devices, thereby reducing the apparatus weight and the loading time.

  • Patent number: 7971177
    Abstract: A method for simulating operation of a charge trapping memory cell which computes the amount of charge trapped by determining first tunneling current through the tunneling layer, determining second tunneling current out of the charge trapping layer to the gate, determining third tunneling current escaping from traps in the charge trapping layer and tunneling out to the gate, and integrating said tunneling currents over a time interval. A change in threshold voltage can be computed for a transistor including the charge trapping structure. The parameter set can include only physical parameters, including layer thickness, band offsets and dielectric constants.

    Abstract: A test handler is disclosed. The test handler includes first to third transfers for transferring a user tray, and first to third horizontal movement units suitable for respectively moving the first to third transfers in a horizontal direction. The first to third horizontal movement units are independently operated such that each of the first to third transfers can perform independently horizontal movements. Each of the first to third transfers performs based on its previously allocated function, thereby enhancing test process speed for devices.

  • Patent number: 7898271
    Abstract: A test handler is disclosed. A posture changing unit for changing a posture of a test tray on which semiconductor devices have been loaded changes the posture of the test tray in a soak chamber. While the posture of the test tray is changed, the devices can be pre-heated/pre-cooled, thereby reducing the soak chamber length and the pre-heating/pre-cooling time.

  • Patent number: 7889556
    Abstract: A memory array comprises a semiconductor body having a plurality of trenches aligned generally in parallel. The trenches contain semiconductor material, such as doped amorphous silicon, and act as source/drain lines for the memory array. Insulating liners lie between the semiconductor material within the trenches and the semiconductor body. A plurality of word lines overlie the plurality of trenches and channel regions in the semiconductor body in an array of cross points. Charge trapping structures lie between the word lines and the channel regions at the cross points, providing an array of flash memory cells. The charge trapping structures comprise dielectric charge trapping structures adapted to be programmed and erased to store data. A method for manufacturing such devices includes patterning and forming the sources/drain lines with insulating liners prior to formation of the charge trapping structure over the channel regions.

  • Publication number: 20100316478
    Abstract: A pick-and-place module for test handlers is disclosed that includes a main body and a kit. The main body forms vacuum paths therein and the kit also forms vacuum passages therein. The kit is detachably mounted to the main body in a hook coupling manner. The pick-and-place module can be applied to all customer trays having different loading capabilities when only the kit of the pick-and-place module needs to be replaced, so there is no need to manufacture the entire pick-and-place module and this reduces manufacturing costs. The pick-and-place module can reduce the amount of resources to be replaced and reduce the replacement time since the kit can be easily removed from the main body of the pick-and-place module in a hook manner.

  • Patent number: 7741836
    Abstract: A test handler is disclosed. First and second gripping blocks for respective front and rear test trays to be transferred along a circulation path move together in a circulation direction, but move independently in a direction perpendicular to the circulation path and grip and release independently. The test trays can be transferred by a single power source and interference between an assisting a test and a transferring can be minimized.
