    Abstract: A semiconductor fabrication process includes forming isolation structures (106) on either side of a transistor region, forming a gate structure (110) overlying the transistor region, removing source/drain regions (107) to form source/drain recesses (120), removing portions of the isolation structures to form recessed isolation structures (126), and filling the source/drain recesses with a source/drain stressor such as an epitaxially formed semiconductor. A lower surface of the source/drain recess is preferably deeper than an upper surface of the recessed isolation structure by approximately 10 to 30 nm. Filling the source/drain recesses may precede or follow forming the recessed isolation structures. An ILD stressor (140) is then deposited over the transistor region such that the ILD stressor is adjacent to sidewalls of the source/drain structure thereby coupling the ILD stressor to the source/drain stressor. The ILD stressor is preferably compressive or tensile silicon nitride and the source/drain structure is preferably silicon germanium or silicon carbon.

    Abstract: A method of forming an electronic device (100) includes etching a portion of a first gate dielectric layer (104) to reduce a thickness of the gate dielectric layer (304) within that portion. In one embodiment, portions not being etched may be covered by mask (206). In another embodiment, different portions may be etched during different times to give different thicknesses for the first gate dielectric layer. In a particular embodiment, a second gate dielectric layer (402) may be formed over the first gate dielectric layer (104, 504, 304) after etching the portion. The second gate dielectric layer (402) can have a dielectric constant greater than the dielectric constant of the first gate dielectric layer (104, 504. 304). Subsequent gate electrode (606) and source/drain region formation can be performed to form a transistor structure (20, 22, 24).

    Abstract: An electronic device (10) can include a transistor structure (50) of a first conductivity type, a field isolation region (22), and a layer (130) of a first stress type overlying the field isolation region. For example, the transistor structure (50) may be a p-channel transistor structure (50) and the first stress type may be tensile, or the transistor structure (60) may be an n- channel transistor structure and the first stress type (70) may be compressive. The transistor structure (50) can include a channel region (54) that lies within an active region. An edge of the active region includes the interface between the channel region (54) and the field isolation region (22). From a top view, the layer can include an edge that lies near the edge of the active region. The positional relationship between the edges can affect carrier mobility within the channel region (54) of the transistor structure (50).

    Abstract: N channel (113, 115) and P channel (111) transistors are enhanced by applying stressor layers of tensile (128) and compressive (126), respectively, over them. A previously unknown problem was discovered concerning the two stressor layers, which both may conveniently be nitride but made somewhat differently. The two stressors have different etch rates which results in deleterious effects when etching a contact hole at the interface between the two stressors. A contact to a gate is often preferably half way between N and P channel transistors which is also the seemingly best location for the border between the two stressor layers. The contact etch at the border can result in pitting of the underlying gate structure or in residual nitride in the contact hole. Therefore, it has been found beneficial to ensure that each contact (154) is at least some predetermined distance from the stressor of the opposite type from the one the contact is passing through.

    Abstract translation: 通过分别在其上施加拉伸(128)和压缩(126)的应力层,增强了N沟道(113,115)和P沟道(111)晶体管。 发现关于两个应力层的以前未知的问题,这两个应力层都可以方便地是氮化的,但是略有不同。 两个应力源具有不同的蚀刻速率,这在蚀刻两个应激物之间的界面处的接触孔时会产生有害影响。 与栅极的接触通常优选地在N沟道晶体管和P沟道晶体管之间的中间,这也是两个应力层之间边界看似最好的位置。 在边界处的接触蚀刻可导致底层栅极结构或接触孔中的残余氮化物的点蚀。 因此,已经发现有益的是确保每个接触件(154)与接触件通过的相反类型的应力器至少一定的距离。
