  • Publication number: 20150287746
    Abstract: In a step F2, an isolation region and an element formation region are formed in an SOI substrate. In a step F3, an SOI region and a bulk region are formed. Here, an isolation insulating film of the isolation region is exposed along the entire perimeter of a sidewall of a step between the SOI region and the bulk region. In a step F4, a gate electrode is formed. In a step F5, extension implantation of a bulk transistor is carried out. Here, treatment for preventing an impurity for extension implantation from being implanted into the SOI region is performed. In a step F6, an elevated epitaxial layer is formed in the SOI region.

  • Patent number: 8604553
    Abstract: The present invention, in a method for manufacturing a semiconductor device having an n-channel transistor and a p-channel transistor each of which has an insulation film of a high electric permittivity, inhibits a foreign matter from adhering to the side of a gate insulation film of the n-channel transistor. Over the main surface of a semiconductor substrate, a functional n-channel transistor is formed in a p-type impurity region and a functional p-channel transistor is formed in an n-type impurity region. A plurality of first peripheral transistors formed in the region other than the functional n-channel transistor in the p-type impurity region are formed so that a peripheral n-type structure and a peripheral p-type structure may coexist in a planar view.

  • Patent number: 8367432
    Abstract: To provide a manufacturing method of a semiconductor device capable of placing a larger number of alignment marks for lithography and PCM and at the same time, preventing information leakage from the PCM. In a portion of a first scribe region sandwiched between first semiconductor chip regions, a first region and a second region are placed in parallel to each other. The first region is equipped with at least one monitor selected from a first monitor for electrically evaluating at least either one of an active element (such as transistor) and a passive element (such as resistor or capacitor), a second monitor for dimensional control, and a third monitor for measuring film thickness. In the second region, an alignment mark for lithography is placed. In the cutting step, the first region is cut off.

  • Patent number: 8211716
    Abstract: The present invention aims to increase the number of test elements of a TEG without increasing the area of each of slice areas. Test electrode pads are disposed in alignment in one row in each of areas separated from semiconductor chips provided over a semiconductor wafer. Test elements are formed corresponding to these test electrode pads and in areas lying directly therebelow. Electrode terminals of the test elements are electrically coupled to the test electrode pads adjacent to the corresponding electrode pads and the test electrode pads further adjacent thereto with being spaced one test electrode pad apart. Upon testing, probe pins are brought into contact with the odd-numbered test electrode pads to conduct testing. Next, the probe pins are brought into contact with the even-numbered test electrode pads while being shifted by one electrode pad pitch thereby to conduct testing.
