  • Patent number: 8384888
    Abstract: A method for measuring a shape of a phase defect existing on an exposure mask includes making inspection light incident on the mask, measuring the intensity of light scattered in an angular range in which the width of an scattering area on the phase defect can be predicted, calculating a radius of the phase defect based on the measured scattered light intensity, changing the angular range of scattered light to be measured, remeasuring scattered light intensity in the thus changed angular range, and calculating a scattering cross-sectional area based on the scattered light intensity obtained by remeasurement. A process of remeasuring the scattered light intensity and calculating the scattering cross-sectional area is repeatedly performed until the remeasured scattered light intensity is saturated and the shape of the phase defect is determined by using the calculated radius of the phase defect and each of the calculated scattering cross-sectional areas.

  • Publication number: 20110275185
    Abstract: A method of manufacturing a semiconductor device with NMOS and PMOS transistors is provided. The semiconductor device can lessen a short channel effect, can reduce gate-drain current leakage, and can reduce parasitic capacitance due to gate overlaps, thereby inhibiting a reduction in the operating speed of circuits. An N-type impurity such as arsenic is ion implanted to a relatively low concentration in the surface of a silicon substrate (1) in a low-voltage NMOS region (LNR) thereby to form extension layers (61). Then, a silicon oxide film (OX2) is formed to cover the whole surface of the silicon substrate (1). The silicon oxide film (OX2) on the side surfaces of gate electrodes (51-54) is used as an offset sidewall. Then, boron is ion implanted to a relatively low concentration in the surface of the silicon substrate (1) in a low-voltage PMOS region (LPR) thereby to form P-type impurity layers (621) later to be extension layers (62).

  • Publication number: 20110207312
    Abstract: A gate insulating film (13) and a gate electrode (14) of non-single crystalline silicon for forming an nMOS transistor are provided on a silicon substrate (10). Using the gate electrode (14) as a mask, n-type dopants having a relatively large mass number (70 or more) such as As ions or Sb ions are implanted, to form a source/drain region of the nMOS transistor, whereby the gate electrode (14) is amorphized. Subsequently, a silicon oxide film (40) is provided to cover the gate electrode (14), at a temperature which is less than the one at which recrystallization of the gate electrode (14) occurs. Thereafter, thermal processing is performed at a temperature of about 1000° C., whereby high compressive residual stress is exerted on the gate electrode (14), and high tensile stress is applied to a channel region under the gate electrode (14). As a result, carrier mobility of the nMOS transistor is enhanced.
