    摘要: A compact contactless trenched flash memory array for semiconductor EEPROM devices is disclosed. The flash memory array comprises a number of memory cell units. Each of the cell units comprises a body line, source and drain regions and a stacked gate constructed over a silicon wafer substrate. The source and drain regions are buried regions and the body line is isolated by the surrounding buried source/drain regions and trenches formed to cut deep down to the substrate of the wafer. The stacked gate includes a first polysilicon layer, an oxide-nitride-oxide configuration, a second polysilicon layer, a pad oxide layer and a nitride layer. The source and drain buried regions sandwiches the body line, and the stacked gate substantially sits directly atop the body line. The flash memory array is free from the serious problem of short channel effect.

    摘要: A process for fabricating compact contactless flash memory array for semiconductor EEPROM devices having a number of memory cell units is disclosed. Field oxide layers for the flash memory array are first grown over the surface of an SOI wafer. Gate oxide layers are then grown. Floating gates are then formed by patterning the first polysilicon layer. Source/drain buried bitlines for the flash memory array are formed. A first BPSG (borophosphosilicate glass) layer is deposited and then reflown and etched back. An oxide-nitride-oxide layer is formed. A second polysilicon layer is deposited with in-situ dope. A WSi.sub.x layer then forms. Stacked gates for the flash array are formed by patterning into the formed oxide-nitride-oxide, second polysilicon and WSi.sub.x layers. The stacked gates are then covered with a second BPSG layer. Contact openings for the source/drain buried lines are formed. Metal lines leading into the contact openings are then formed for interconnecting the memory cells in the flash memory array with peripheral control circuits of the semiconductor EEPROM devices.

    摘要: A first compensation factor, a second compensation factor and a third compensation factor are provided to improve a capacitance-voltage (C-V) method for measuring an effective channel length of a metal-oxide-semiconductor field effect transistor (MOSFET), and an overlap length of a gate and a source and a drain of the transistor. The first compensation factor is calculated by measuring two unit length gate capacitances of the transistor. The second compensation factor is calculated by measuring two unit length overlap capacitances of the transistor. The third compensation factor is a ratio of the second compensation factor to the first compensation factor.

    摘要: A method of forming a self-aligned silicide layer. A planarization process is performed to form a gate with a planar top surface. Due to the planar top surface of the gate, the reactivity and the uniformity of thickness of the subsequently formed silicide layer on the top surface of the gate are improved, such that the resistance of the silicide is reduced, and the performance of the device is improved.

    摘要: A method of fabricating a flash memory is described. First, a shallow trench isolation structure is formed on the substrate, so that the surface of the shallow trench isolation structure is projected above the surface of the substrate. Then, a spacer is formed on the sidewall of the shallow trench isolation structure, which projects above the surface of the substrate. With the spacer serving as a mask, a gate oxide layer not covered by the spacer is etched to expose the substrate. By thermal oxidation, a self-aligned tunneling oxide layer is formed on the exposed substrate. The spacer is then removed. A floating gate is formed on the tunneling oxide layer. In addition, a dielectric layer and a control gate are formed on the floating gate in sequence, thus completing the flash memory structure.

    摘要: A method of fabricating a conductive line structure. A first dielectric layer is formed on a substrate. A conductive layer is formed on the first dielectric layer. The conductive layer is patterned to form an opening in the conductive layer. The opening exposes a portion of the first dielectric layer. A conformal stop layer is formed over the substrate. The conformal stop layer is conformal to the conductive layer. An oxide layer is formed in the opening. The oxide layer does not completely fill the opening. A portion of a sidewall of the opening is exposed. A spacer is formed on the exposed sidewall of the opening. The oxide layer is removed. A second dielectric layer is formed over the substrate to fill the opening. A void is formed in the second dielectric layer in the opening.
