Abstract: A method for programming and erasing an array of NMOS electrically erasable programmable read only memory (EEPROM) cells that minimizes bit disturbances and high voltage requirements for the memory array cells and supporting circuits. In addition, the array of N-channel memory cells may be separated into independently programmable memory segments by creating multiple, electrically isolated P-wells upon which the memory segments are fabricated. The multiple, electrically isolated P-wells may be created, for example, by p-n junction isolation or dielectric isolation.

Abstract: Disclosed are methods for facilitating concurrent formation of copper vias and memory element structures. The methods involve forming vias over metal lines and forming copper plugs, wherein the copper plugs comprise memory element film forming copper plugs (memE copper plugs) and non-memory element forming copper plugs (non-memE copper plugs), forming a tantalum-containing cap over an upper surface of non-memE copper plugs, and depositing memory element films. The tantalum-containing cap prevents the formation of the memory element films in the non-memE copper plugs. The subject invention advantageously facilitates cost-effective manufacturing of semiconductor devices.

Abstract: The subject invention provides systems and methodologies for fabrication of memory and/or selection (e.g., diodes) elements in a recession in a semiconductor layer. In particular, a trench of varying width is created in the semiconductor layer by employing various etching techniques. A metal film can be deposited in the trench according to a desired deposition thickness in order to seam close a narrow portion of the trench while form a dimple in a wide portion of the trench. The trench, after metal film deposition, exhibits a depression in wider trench portions relative to narrow trench portions. The depression can be utilized by placing one or more memory or selection layers in the depression, and a via can be formed over a portion of the trench to form an interconnect.

Abstract: Methods of making a semiconductor structure are disclosed. A refractory metal layer containing W, TiW, Ta, or TaN and semiconductor layer are formed on a substrate that contains copper in, for example, a via therein. A portion of the refractory metal layer and semiconductor layer is removed by etching using a fluorine-containing compound. By using W, TiW, Ta, or TaN as the refractory metal layer material and employing fluorine-based etching, the copper portion in the substrate is not substantially etched, thus preventing corrosion of the copper portion.

Abstract: In a two-step spacer fabrication process for a non-volatile memory device, a thin oxide layer is deposited on a wafer substrate leaving a gap in the core of the non-volatile memory device. Implantation and/or oxide-nitride-oxide removal can be accomplished through this gap. After implantation, a second spacer is deposited. After the second spacer deposition, a periphery spacer etch is performed. By the above method, a spacer is formed.

Abstract: A method of preventing UV charging of flash NVROM cells during fabrication and a device thereby formed. During device fabrication, a UV blocking layer is deposited over the floating gates. The UV blocking layer substantially blocks UV from entering the gate regions so as to prevent electron mobility sufficient to render the cells unprogrammable or unerasable. The reduced electron migration during processing of the NVROM leads to increased yield and reliability of the devices.

Abstract: The degradation of deposited low dielectric constant interlayer dielectrics and gap fill layers, such as HSQ layers, during formation of contacts/vias is significantly reduced or prevented by employing a plasma containing CF4+H2O to remove the photoresist mask and cleaning the contact/via opening after anisotropic etching. The CF4+H2O plasma also enables rapid photoresist stripping at a rate of about 10 to about 20 KÅ/min. Embodiments include photoresist stripping and cleaning the contact/via opening with a CF4+H2O plasma to prevent reduction of the number of Si—H bonds of an as-deposited HSQ layer below about 70%.
