Abstract: A semiconductor structure is provided which includes a first semiconductor device in a first active semiconductor region and a second semiconductor device in a second active semiconductor region. A first dielectric liner overlies the first semiconductor device and a second dielectric liner overlies the second semiconductor device, with the second dielectric liner overlapping the first dielectric liner at an overlap region. The second dielectric liner has a first portion having a first thickness contacting an apex of the second gate conductor and a second portion extending from peripheral edges of the second gate conductor which has a second thickness substantially greater than the first thickness. A first conductive via contacts at least one of the first or second gate conductors and the conductive via extends through the first and second dielectric liners at the overlap region.

Abstract: Electrically programmable integrated fuses are provided for low power applications. Integrated fuse devices have stacked structures with a polysilicon layer and a conductive layer formed on the polysilicon layer. The integrated fuses have structural features that enable the fuses to be reliably and efficiently programmed using low programming currents/voltages, while achieving consistency in fusing locations. For example, programming reliability and consistency is achieved by forming the conductive layers with varied thickness and forming the polysilicon layers with varied doping profiles, to provide more precise localized regions in which fusing events readily occur.

Abstract: A transistor and method of formation thereof includes source and drain extension regions in which the diffusion of dopants into the channel region is mitigated or eliminated. This is accomplished, in part, by elevating the source and drain extension regions into the epitaxial layer formed on the underlying substrate. In doing so, the effective channel length is increased, while limiting dopant diffusion into the channel region. In this manner, performance characteristics of the transistor can be accurately determined by controlling the respective geometries (i.e. depths and widths) of the source/drain extension regions, the source/drain regions, the channel width and an optional trench formed in the underlying substrate. In the various embodiments, the source/drain regions and the source/drain extension regions may extend partially, or fully, through the epitaxial layer, or even into the underlying semiconductor substrate.

A single mask may be used to define the second active area for removal of the photoresist layer on the first active area and for implanting source/drain regions into the second active area.

Abstract: Methods of forming field effect transistors include methods of forming PMOS and NMOS transistors by forming first and second gate electrodes on a substrate and then forming an electrically insulating layer having etch-enhancing impurities therein, on the first and second gate electrodes. The electrically insulating layer may be formed as a boron-doped silicon nitride layer or an electrically insulating layer that is doped with germanium and/or fluorine. The electrically insulating layer is etched-back to define first sidewall spacers on the first gate electrode and second sidewall spacers on the second gate electrode. P-type source and drain region dopants are then implanted into the semiconductor substrate, using the first sidewall spacers as a first implant mask. The second sidewall spacers on the second gate electrode are then etched back to reduce their lateral dimensions.

Abstract: A transistor and method of formation thereof includes source and drain extension regions in which the diffusion of dopants into the channel region is mitigated or eliminated. This is accomplished, in part, by elevating the source and drain extension regions into the epitaxial layer formed on the underlying substrate. In doing so, the effective channel length is increased, while limiting dopant diffusion into the channel region. In this manner, performance characteristics of the transistor can be accurately determined by controlling the respective geometries (i.e. depths and widths) of the source/drain extension regions, the source/drain regions, the channel width and an optional trench formed in the underlying substrate. In the various embodiments, the source/drain regions and the source/drain extension regions may extend partially, or fully, through the epitaxial layer, or even into the underlying semiconductor substrate.
