  • Publication number: 20110147852
    Abstract: In semiconductor devices in which both NMOS devices and PMOS devices are used to perform in different modes such as analog and digital modes, stress engineering is selectively applied to particular devices depending on their required operational modes. That is, the appropriate mechanical stress, i.e., tensile or compressive, can be applied to and/or removed from devices, i.e., NMOS and/or PMOS devices, based not only on their conductivity type, i.e., n-type or p-type, but also on their intended operational application, for example, analog/digital, low-voltage/high-voltage, high-speed/low-speed, noise-sensitive/noise-insensitive, etc. The result is that performance of individual devices is optimized based on the mode in which they operate.
