  • Patent number: 9496187
    Abstract: A multiple-sample-holder polishing setup for cross-section sample preparation and a method of making a device using the same are presented. The multiple-sample-holder polishing setup includes a frame. The frame has a hollow center, one or more long and short rods and a recess for accommodating a polishing head. The setup includes one or more sample holders. The sample holder is to be attached to the one or more long and short rods of the frame. A paddle is affixed to each sample holder. A sample is attached to the paddle. The sample is coated with a thin epoxy layer prior to polishing thereby allowing for easy inspection for site of interests as well as quick material removal.

  • Patent number: 8489945
    Abstract: According to an embodiment of the disclosure, a method verifies bitmap information or test data information for a semiconductor device. The method places a defect on a semiconductor device at an actual defect location using a laser to physically damage the semiconductor device. A logical address associated with the defect is detected and bitmap information or test data information is reviewed to determine an expected location corresponding to the logical address. Then, the accuracy of the bitmap information or the test data information is determined by comparing the actual defect location with the expected location. A deviation between the two indicates an inaccuracy.

  • Patent number: 7718987
    Abstract: A memory cell for an electrically writeable and erasable memory medium as well as a memory medium thereof is provided. The memory cell comprises a data recording element, the data recording element has a plurality of multiple-layer structure disposed one on top of another; each the multiple-layer structure comprising a plurality of sequentially disposed individual layers. At least one of the plurality of individual layers is capable of changing phase between a crystalline state and an amorphous state in response to an electrical pulse, one of the plurality of individual layers having at least one atomic element which is absent from other one of the plurality of individual layers, and the plurality of multiple-layer structure is of a superlattice-like structure to lower a heat diffusion out of the data recording element to shorten a phase change time of the respective individual layers.

  • Publication number: 20020150716
    Abstract: In data-storage media such as rewritable optical discs (DVD−RAM, DVD+RW, DVD−RW, DVR, CD−RW and PD), the current need for the disc to be initialised before it can be used is eliminated. This is achieved by depositing on the disc, immediately before and/or after the record layer itself has been deposited, a layer of additional material that induces the record layer to become deposited in its crystalline state, or to be transformed spontaneously into that state. One specific material, which has this effect on record layers of GeSbTe and/or AgInSbTe, is Sb2Te3.
