  • Patent number: 8769102
    Abstract: In one aspect, a first request is received at a configuration server for access to a first virtual test environment. The first request is received from a first client device over a network and specifies one or more configuration options associated with the first virtual test environment. It is determined that a user of the first client device belongs to a first group out of multiple groups. A first pool of resources is selected based on the user of the first client device belonging to the first group, wherein the first pool of resources are available to members of the first group but not available to members of a second group out of the multiple groups. A first virtual machine is provisioned using the selected first pool of resources that includes the first virtual test environment, the first virtual test environment including features associated with the one or more configuration options associated with the first virtual test environment.

  • Patent number: 8610220
    Abstract: A semiconductor device and method for fabricating a semiconductor device is disclosed. An exemplary semiconductor device includes a substrate including a metal oxide device. The metal oxide device includes first and second doped regions disposed within the substrate and interfacing in a channel region. The first and second doped regions are doped with a first type dopant. The first doped region has a different concentration of dopant than the second doped region. The metal oxide device further includes a gate structure traversing the channel region and the interface of the first and second doped regions and separating source and drain regions. The source region is formed within the first doped region and the drain region is formed within the second doped region. The source and drain regions are doped with a second type dopant. The second type dopant is opposite of the first type dopant.
