摘要： A method of detecting low-probability defects in large transistor arrays (such as large arrays of SRAM cells), where the defects manifest themselves as asymmetrical leakage in a transistor (such as a pulldown nFET in an SRAM cell). These defects are detected by creating one or more test arrays, identical in all regards to the large transistor arrays up until the contact and metallization layers. Leakage is measured by applying an appropriate off-state voltage (e.g., 0V) by a common connection to all of the gates of the transistors in the test array, then measuring the aggregate drain/source leakage current, both forward and reverse (e.g., first grounded source and positively biased drain, then grounded drain and positively biased source) comparing the difference between the two leakage current measurements.

摘要： An interconnect structure having improved electromigration (EM) reliability is provided. The inventive interconnect structure avoids a circuit dead opening that is caused by EM failure by incorporating a EM preventing liner at least partially within a metal interconnect. In one embodiment, a “U-shaped” EM preventing liner is provided that abuts a diffusion barrier that separates conductive material from the dielectric material. In another embodiment, a space is located between the “U-shaped” EM preventing liner and the diffusion barrier. In yet another embodiment, a horizontal EM liner that abuts the diffusion barrier is provided. In yet a further embodiment, a space exists between the horizontal EM liner and the diffusion barrier.

摘要： An interconnect structure having an incomplete via opening is processed to deepen a via opening and to expose a metal line. In case the interconnect structure comprises a metal pad or a blanket metal layer, the metal pad or the metal layer is removed selective to an underlying dielectric layer to expose the incomplete via opening. Another dielectric layer is formed within the incomplete via opening to compensated for differences in the total dielectric thickness above the metal line relative to an optimal dielectric stack. A photoresist is applied thereupon and patterned. An anisotropic etch process for formation of a normal via opening may be employed with no or minimal modification to form a proper via opening and to expose the metal line. A metal pad is formed upon the metal line so that electrical contact is provided between the metal pad and the metal line.

摘要： The present invention provides a method of fabricating semiconductor device comprising at least one field effect transistor (FET) having source and drain (S/D) metal silicide layers with intrinsic tensile or compressive stress. First, a metal layer containing a silicide metal M is formed over S/D regions of a FET, followed by a first annealing step to form S/D metal silicide layers that comprise a metal silicide of a first phase (MSix). A silicon nitride layer is then formed over the FET, followed by a second annealing step. During the second annealing step, the metal silicide is converted from the first phase (MSix) into a second phase (MSiy) with x

摘要： Methods and a structure are disclosed for providing stacking fault reduced epitaxially grown silicon for use in hybrid surface orientation structures. In one embodiment, a method includes depositing a silicon nitride liner over a silicon oxide liner in an opening, etching to remove the silicon oxide liner and silicon nitride liner on a lower surface of the opening, undercutting the silicon nitride liner adjacent to the lower surface, and epitaxially growing silicon in the opening. The silicon is substantially reduced of stacking faults because of the negative slope created by the undercut.
