    Abstract: Accordingly, the present invention provides a double gated transistor and a method for forming the same that results in improved device performance and density. The preferred embodiment of the present invention uses provides a double gated transistor with asymmetric gate doping, where one of the double gates is doped degenerately n-type and the other degenerately p-type. By doping on of the gates n-type, and the other p-type, the threshold voltage of the resulting device is improved. In particular, by asymmetrically doping the two gates, the resulting transistor can, with adequate doping of the body, have a threshold voltage in a range that enables low-voltage CMOS operation. For example, a transistor can be created that has a threshold voltage between 0V and 0.5V for nFETs and between 0 and -0.5V for pFETs.

    Abstract: A method and structure for an integrated circuit structure that utilizes complementary fin-type field effect transistors (FinFETs) is disclosed. The invention has a first-type of FinFET which includes a first fin (100), and a second-type of FinFET which includes a second fin (102) running parallel to the first fin (100). The invention also has an insulator fin positioned between the source/drain regions (130) of the first first-type of FinFET and the second-type of FinFET. The insulator fin has approximately the same width dimensions as the first fin (100) and the second fin (102), such that the spacing between the first-type of FinFET and the second-type of FinFET is approximately equal to the width of one fin. The invention also has a common gate (106) formed over channel regions of the first-type of FinFET and the second-type of FinFET. The gate (106) includes a first impurity doping region adjacent the first-type of FinFET and a second impurity doping region adjacent the second-type of FinFET. The differences between the first impurity doping region and the second impurity doping region provide the gate with different work functions related to differences between the first-type of FinFET and the second-type of FinFET. The first fin (100) and the second fin (102) have approximately the same width.

    Abstract: An integrated circuit semiconductor memory device (100) has a first dielectric layer (116) characterized as the BOX layer absent from a portion (130) of the substrate (112) under the gate of a storage transistor to increase the gate-to-substrate capacitance and thereby reduce the soft error rate. A second dielectric layer (132) having a property different from the first dielectric layer at least partly covers that portion (130) of the substrate. The device may be a FinFET device including a fin (122) and a gate dielectric layer (124, 126) between the gate and the fin, with the second dielectric layer having less leakage than the gate dielectric layer.

    Abstract: A method is provided for fabricating a finFET device. Fin structures are formed over a BOX layer. The fin structures include a semiconductor layer and extend in a first direction. A gate stack is formed on the BOX layer over the fin structures and extending in a second direction. The gate stack includes a high-K dielectric layer and a metal gate. Gate spacers are formed on sidewalls of the gate stack, and an epi layer is deposited to merge the fin structures. Ions are implanted to form source and drain regions, and dummy spacers are formed on sidewalls of the gate spacers. The dummy spacers are used as a mask to recess or completely remove an exposed portion of the epi layer. Silicidation forms silicide regions that abut the source and drain regions and each include a vertical portion located on the vertical sidewall of the source or drain region.
