    摘要: A multiple independent bit Flash memory cell has a gate that includes a first oxide layer, a discontinuous nitride layer on the first oxide layer, a second oxide layer on the discontinuous nitride layer and the first oxide layer, and a polysilicon layer on the second oxide layer. The discontinuous nitride layer has regions residing at different portions of the layer. These portions are separated by the second oxide layer. Thus, with a smaller channel length, charge that otherwise would migrate from one region to the other and/or strongly influence its neighboring it is blocked/impeded by the second oxide layer. In this manner, the potential for charge sharing between the regions is reduced, and a higher density chip multiple independent bit Flash memory cells may be provided.

    摘要: A method and system for providing at least one contact in a semiconductor device. The semiconductor device includes a substrate, an etch stop layer, an interlayer dielectric on the etch stop layer, an anti-reflective coating layer on the interlayer dielectric, and at least one feature below the etch stop layer. A resist mask having an aperture and residing on the anti-reflective coating layer is provided. The aperture is above an exposed portion of the anti-reflective coating layer. The method and system include etching the exposed anti-reflective coating layer and the underlying interlayer dielectric without etching through the etch stop layer, thereby providing a portion of at least one contact hole. The method and system also include removing the resist mask in situ, removing a portion of the etch stop layer exposed in the portion of the contact hole, and filling the contact hole with a conductive material.

    摘要: A method for in-line testing of a chip to include multiple independent bit Flash memory devices, includes the steps of: grounding every other polysilicon line on the chip to emulate the multiple independent bit Flash memory devices, where an oxide line reside between every two polysilicon lines; scanning the polysilicon lines with an electron beam; examining voltage contrasts between the polysilicon lines; and determining if there are consecutively grounded polysilicon lines based on the voltage contrasts. If consecutive polysilicon lines appear to be grounded, then this indicates that a bridge defect exists between two of the consecutively grounded polysilicon lines. With this method, bridge defects in multiple independent bit Flash memory devices are better detected, leading to improved yield and reliability of the devices.

    摘要: A method for evaluating the effect of crystalline originated pits (COP's) in a silicon substrate on semiconductor devices method locates a first test structure created on a COP on the substrate and a second test structure created on the substrate but not on a COP. The electrical properties of the first and second test structure are then examined and compared. If there is a difference in their electrical properties, then the COP would affect a structure similar to the test structures of a semiconductor device. In this manner, the effects of COP's on the yield for the substrate can be understood.
