  • Patent number: 8709956
    Abstract: BEOL memory cells are described that include one or more sidewall protection layers on the memory device (including, for example, an MTJ element) deposited prior to interconnect via etching to prevent the formation of electrical shorts between layers. One embodiment uses a single layer sidewall protection sleeve that is deposited after the memory device has been patterned. The layer material is vertically etched down to expose the upper surface of the top electrode while leaving a residual layer of protective material surrounding the rest of the memory device. The material for the protection layer is selected to resist the etchant used to remove the first dielectric material from the via in the subsequent interconnect process. A second embodiment uses dual-layer sidewall protection in which the first layer covers the memory element is preferably an oxygen-free dielectric and the second layer protects the first layer during via etching.

  • Patent number: 7812352
    Abstract: A TFT array substrate is disclosed. In the pixel structure of the TFT array substrate, patterned transparent conductive layers are disposed under a first metal layer (M1) and a second metal layer (M2) and most areas of the M1 and M2 are substituted by the patterned transparent conductive layers. So, the pixel structure has high aperture ratio and large storage capacitance. Besides, a scan bonding pad on the TFT array substrate includes a first patterned transparent conductive layer (T1), the M1 and a third patterned transparent conductive layer (T3). The M1 is disposed on the T1, and the T3 is electrically connected to the T1 via a contact hole in the M1. So, the contact resistance of the scan bonding pad is small. The data bonding pad on the TFT array substrate has similar design. Moreover, fabricating methods of TFT array substrates are also provided.

  • Patent number: 7700462
    Abstract: When the CW laser oscillator is employed in the manufacturing process of the semiconductor device, it is expected to obtain the device of high performance. However, the CW oscillator provides only a small beam spot and forms an inferior crystalline region when it is scanned on the semiconductor film. It is necessary to minimize such an inferior crystalline region because it gives a problem in terms of high integration of the semiconductor element. In view of the problem, the present invention is to form a long crystalline region as suppressing the formation of the inferior crystalline region by irradiating the fundamental wave with the harmonic supplementarily (refer to FIG. 1). The present invention also includes a constitution in which a part having high energy density in the fundamental wave is irradiated to a part having low energy density in the harmonic.
