    摘要： A phase-change memory cell is formed by a phase-change memory element and by a selection element, which is formed in a semiconductor material body and is connected to the phase-change memory element. The phase-change memory element is made up of a calcogenic material layer and a heater. The selection element is in direct contact with the heater and extends through a dielectric region arranged on top of and contiguous to the semiconductor material body. A dielectric material layer is arranged on the dielectric region and houses a portion of the calcogenic material layer.

    摘要： Methods and memory devices formed using etch bias homogenization are provided. One example method of forming a memory device using etch bias homogenization includes forming conductive material at respective levels over a substrate. Each respective level of conductive material is electrically coupled to corresponding circuitry on the substrate during patterning of the respective level of conductive material so that each respective level of conductive material has a homogenized etch bias during patterning thereof. Each respective level of conductive material electrically coupled to corresponding circuitry on the substrate is patterned.

    摘要： Small phase change memory cells may be formed by forming a segmented heater over a substrate. A stop layer may be formed over the heater layer and segmented with the heater layer. Then, sidewall spacers may be formed over the segmented heater to define an aperture between the sidewall spacers that may act as a mask for etching the stop layer over the segmented heater. As a result of the etching using the sidewall spacers as a mask, sublithographic pore may be formed over the heater. Phase change material may be formed within the pore.

    摘要： Memory cells, arrays of memory cells, and methods of forming the same with sealing material on sidewalls thereof are disclosed herein. One example of forming a memory cell includes forming a stack of materials, forming a trench to a first depth in the stack of materials such that a portion of at least one of the active storage element material and the active select device material is exposed on sidewalls of the trench. A sealing material is formed on the exposed portion of the at least one of the active storage element material and the active select device material and the trench is deepened such that a portion of the other of the at least one of the active storage element material and the active select device material is exposed on the sidewalls of the trench.

    摘要： A plurality of bipolar transistors are formed by forming a common conduction region, a plurality of control regions extending each in an own active areas on the common conduction region, a plurality of silicide protection strips, and at least one control contact region. Silicide regions are formed on the second conduction regions and the control contact region. The second conduction regions may be formed by selectively implanting a first conductivity type dopant areas on a first side of selected silicide protection strips. The control contact region is formed by selectively implanting an opposite conductivity type dopant on a second side of the selected silicide protection strips.
