20140167128 | Memory Gate Landing Pad Made From Dummy Features - Embodiments described herein generally relate to landing gate pads for contacts and manufacturing methods therefor. A bridge is formed between two features to allow a contact to be disposed, at least partially, on the bridge. Landing the contact on the bridge avoids additional manufacturing steps to create a target for a contact. | 06-19-2014 |
20140167135 | Process Charging Protection for Split Gate Charge Trapping Flash - A semiconductor device and method of making such device is presented herein. The semiconductor device includes a plurality of memory cells, a plurality of p-n junctions, and a metal trace of a first metal layer. Each of the plurality of memory cells includes a first gate disposed over a first dielectric, a second gate disposed over a second dielectric and adjacent to a sidewall of the first gate, a first doped region in the substrate adjacent to the first gate, and a second doped region in the substrate adjacent to the second gate.

20140167136 | Charge Trapping Device with Improved Select Gate to Memory Gate Isoloation - Embodiments described herein generally relate to charge-trapping memory with improved isolation between a select gate and a memory gate. The isolation is improved because the charge trapping layer is not present in the junction between the select gate and the memory gate. The methods described herein additionally allow insulation to be disposed between the select gate and the memory gate. | 06-19-2014 |

20140167141 | Charge Trapping Split Gate Embedded Flash Memory and Associated Methods - Semiconductor devices and methods of manufacturing such devices are described herein. According to embodiments, the semiconductor device can be made by forming an dielectric layer at a first region and at a second region of a semiconductor substrate. A gate conductor layer is disposed over the dielectric formed in the first and the second regions of the semiconductor substrate, and the second region is masked. A split gate memory cell is formed in the first region of the semiconductor substrate with a first gate length. The first region is then masked, and the second region is etched to define a logic gate that has a second gate length. The first and second gate lengths can be different. | 06-19-2014 |
20140167142 | Use Disposable Gate Cap to Form Transistors, and Split Gate Charge Trapping Memory Cells - A semiconductor device and method of making such device is presented herein. The method includes disposing a gate layer over a dielectric layer on a substrate and further disposing a cap layer over the gate layer. A first transistor gate is defined having an initial thickness substantially equal to a combined thickness of the cap layer and the gate layer. A first doped region is formed in the substrate adjacent to the first transistor gate. The cap layer is subsequently removed and a second transistor gate is defined having a thickness substantially equal to the thickness of the gate layer. Afterwards, a second doped region is formed in the substrate adjacent to the second transistor gate. The first doped region extends deeper in the substrate than the second doped region, and a final thickness of the first transistor gate is substantially equal to the thickness of the second transistor gate. | 06-19-2014 |
20140167220 | THREE DIMENSIONAL CAPACITOR - Integrated capacitor structures and methods for fabricating same are provided. In an embodiment, the integrated capacitor structures exploit the capacitance that can be formed in a plane that is perpendicular to that of the substrate, resulting in three-dimensional capacitor structures. This allows for integrated capacitor structures with higher capacitance to be formed over relatively small substrate areas. Embodiments are suitable for use by charge pumps and can be fabricated to have more or less capacitance as desired by the application. | 06-19-2014 |
