    Abstract: A method of fabricating a semiconductor connective region of a first conductivity type through a semiconductor layer of a second conductivity type which at least partly separates a bulk portion of semiconductor body (substrate) of the first conductivity type from a semiconductor well of the first conductivity type includes a step of implanting ions into a portion of the layer to convert the conductivity of the implanted portion to the first conductivity type. This electrically connects the well to the bulk portion of the body. Any biasing potential applied to the bulk portion of the body is thus applied to the well. This eliminates any need to form a contact in the well for biasing the well and thus allows the well to be reduced in size.

    Abstract: A method for fabricating a semiconductor component having a low contact resistance with respect to heavily doped or siliconized zones in a semiconductor body. Fluorine ions are implanted into the heavily doped or siliconized zone in the vicinity of a contact hole before a titanium layer is applied to the heavily doped or siliconized zone in the vicinity of the contact hole. As a result of the fluorine, any oxide layers present in the contact hole region can be broken up by less titanium, with the result that a thinner titanium layer is sufficient. In addition, the formation of titanium silicide in the contact hole is promoted.
