    摘要: The present invention provides a method of forming, in semiconductor substrates, contact openings having low contact resistance. The method involves, in particular, the introduction of a “soft etch” cleaning step that is used to clean the bottom of the contact openings. The “soft etch” cleaning step uses fluorocarbon chemistry. It is shown that the resulting resistance of the contact openings is reduced.

    摘要: According to various embodiments, a resistive-switching memory element and memory element array that uses a bipolar switching includes a select element comprising only a single diode that is not a Zener diode. The resistive-switching memory elements described herein can switch even when a switching voltage less than the breakdown voltage of the diode is applied in the reverse-bias direction of the diode. The memory elements are able to switch during the very brief period when a transient pulse voltage is visible to the memory element, and therefore can use a single diode per memory cell.

    摘要: In embodiments of the current invention, methods of combinatorial processing and a test chip for use in these methods are described. These methods and test chips enable the efficient development of materials, processes, and process sequence integration schemes for semiconductor manufacturing processes. In general, the methods simplify the processing sequence of forming devices or partially formed devices on a test chip such that the devices can be tested immediately after formation. The immediate testing allows for the high throughput testing of varied materials, processes, or process sequences on the test chip. The test chip has multiple site isolated regions where each of the regions is varied from one another and the test chip is designed to enable high throughput testing of the different regions.

    摘要: This disclosure provides a nonvolatile memory device and related methods of manufacture and operation. The device may include one or more resistive random access memory (RRAM) that use techniques to provide a memory device with more predictable operation. In particular, forming voltage required by particular designs may be reduced through the use of a barrier layer, a reverse polarity forming voltage pulse, a forming voltage pulse where electrons are injected from a lower work function electrode, or through the use of an anneal in a reducing environment. One or more of these techniques may be applied, depending on desired application and results.
