    Abstract: A method of manufacturing an integrated circuit structure forms a first opening in a substrate (100; Figure 1) and lines the first opening with a protective liner. (102) The method deposits a material into the first opening (104) and forms a protective material over the substrate. The protective material includes a process control mark and includes a second opening above, and aligned with, the first opening. (108) The method removes the material from the first opening through the second opening in the protective material. (110) The process control mark comprises a recess within the protective material that extends only partially through the protective material, such that portions of the substrate below the process control mark are not affected by the process of removing the material.

    Abstract: A chip includes a CMOS structure having a bulk device (20) disposed in a first region (24) of a semiconductor substrate (50) in conductive communication with an underlying bulk region (18) of the substrate, the first region (24) and the bulk region (20) having a first crystal orientation. A SOI device (10) is disposed in a semiconductor-on-insulator ("SOI") layer (14) separated from the bulk region of the substrate by a buried dielectric layer (16), the SOI layer having a different crystal orientation from the first crystal orientation. In one example, the bulk device includes a p-type field effect transistor ("PFET") and the SOI device includes an n-type field effect transistor ("NFET") device. Alternatively, the bulk device can include an NFET and the SOI device can include a PFET. When the SOI device has a gate conductor (11) in conductive communication with a gate conductor (21) of the bulk device, charging damage can occur to the SOI device, except for the presence of diodes in reverse-biased conductive communication with the bulk region. The diodes are operable to conduct a discharge current to the bulk region when either a voltage on the gate conductor or a voltage on the source or drain region of the SOI device exceeds a diode's breakdown voltage.

    Abstract: An image sensor (20) and method of fabrication wherein the sensor includes Copper (Cu) metallization levels (135a, 135b) allowing for incorporation of a thinner interlevel dielectric stack (130a-130c) to result in a pixel array (100) exhibiting increased light sensitivity. The image sensor includes structures having a minimum thickness of barrier layer metal (132a, 132b) that traverses the optical path of each pixel in the sensor array or, that have portions (50) of barrier layer metal selectively removed from the optical paths of each pixel, thereby minimizing reflectance. That is, by implementing various block or single mask methodologies, portions of the barrier layer metal are completely removed at locations of the optical path for each pixel in the array. In a further embodiment, the barrier metal layer (142) may be formed atop the Cu metallization by a self-aligned deposition.
