The work function metal can be recessed after the recessing of the cobalt gate electrode is completed or during the recessing of the cobalt gate electrode. |

Inspection device and substrate processing apparatus
Surface image data of a non-defective sample substrate is acquired, and surface image data of a substrate to be inspected is acquired. Differences between gradation values are calculated for pixels of the surface image data of the substrate to be inspected and corresponding pixels of the surface image data of the sample substrate. A constant value is added to the difference between gradation values of each pixel. In the case where the value acquired by addition is in a predetermined allowable range, it is determined that there is no defect for the substrate to be inspected. In the case where the value acquired by addition is outside of the allowable range, it is determined that the substrate to be inspected is defective. A defect in appearance on the substrate to be inspected is detected based on a pixel of which the value is outside of the allowable range. |

Advanced interconnect with air gap
Ultra-low-k dielectric materials used as inter-layer dielectrics in high-performance integrated circuits are prone to be structurally unstable. The Young's modulus of such materials is decreased, resulting in porosity, poor film strength, cracking, and voids. An alternative dual damascene interconnect process incorporates air gaps into a high modulus dielectric material to maintain structural stability while reducing capacitance between adjacent nanowires. Incorporation of an air gap having k=1.0 compensates for the use of a higher modulus film having a dielectric constant greater than the typical ultra-low-k (ULK) dielectric value of about 2.2. The higher modulus film containing the air gap is used as an insulator between adjacent metal lines, while a ULK film is retained to insulate vias. The dielectric layer between two adjacent metal lines thus forms a ULK/high-modulus dielectric bi-layer. |
