  • Patent number: 9178070
    Abstract: The present application discloses a semiconductor structure and a method for manufacturing the same. A semiconductor structure according to the present invention can adjust the threshold voltage by capacitive coupling between a backgate region either and a source region or a drain region with a common contact, i.e. a source contact or a drain contact, which leads to a simple manufacturing process, a higher integration level, and a lower manufacture cost. Moreover, the asymmetric design of the backgate structure, together with the doping of the backgate region which can be varied as required in an actual device design, can further enhance the effects of adjusting the threshold voltage and improve the performances of the device.

  • Patent number: 9029171
    Abstract: The present disclosure relates to a structure and method to create a self-repairing dielectric material for semiconductor device applications. A porous dielectric material is deposited on a substrate, and exposed with treating agent particles such that the treating agent particles diffuse into the dielectric material. A dense non-porous cap is formed above the dielectric material which encapsulates the treating agent particles within the dielectric material. The dielectric material is then subjected to a process which creates damage to the dielectric material. A chemical reaction is initiated between the treating agent particles and the damage, repairing the damage. A gradient concentration resulting from the consumption of treating agent particles by the chemical reaction promotes continuous diffusion the treating agent particles towards the damaged region of the dielectric material, continuously repairing the damage.
