Abstract: The invention is directed to ion implantation. Ion implantation is a process whereby energetic ions are used to uniformly irradiate the surface of a material—typically a semiconductor wafer.

Post-analysis acceleration and scanning of the beam is done prior to sample irradiation. Each dopant-type acts, in general, to increase the conductivity of the silicon.

Abstract: The present invention discloses a method for controlling the impurity density distribution in semiconductor device and a semiconductor device made thereby. The control method includes the steps of: providing a substrate; defining a doped area which includes at least one first region; partially masking the first region by a mask pattern; and doping impurities in the doped area to form one integrated doped region in the first region, whereby the impurity concentration of the first region is lower than a case where the first region is not masked by the mask pattern.
Abstract: The invention relates to a method for selective deposition of Si or SiGe on a Si or SiGe surface. The method exploits differences in physico-chemical surface behavior according to a difference in doping of first and second surface regions. By providing at least one first surface region with a Boron doping of a suitable concentration range and exposing the substrate surface to a cleaning and passivating ambient atmosphere in a prebake step at a temperature lower or equal than 800° C., a subsequent deposition step of Si or SiGe will not lead to a layer deposition in the first surface region. This effect is used for selective deposition of Si or SiGe in the second surface region, which is not doped with Boron in the suitable concentration range, or doped with another dopant, or not doped. The method thus saves a usual photolithography sequence required for selective deposition of Si or SiGe in the second surface region according to the prior art.

Further, after the vacuum venting process, the wafer may wait an extra time in the load lock chamber before the wafer is moved out the ion implanter, in order to allow the wafer temperature to reach a higher temperature quickly for minimizing water condensation on the wafer surface. Furthermore, to accurately monitor the wafer temperature during a period of changing wafer temperature, a non-contact type temperature measuring device may be used to monitor wafer temperature in a real time manner with minimized condensation.
