    摘要: Formation of a barrier region in a single crystal group IV semiconductor substrate at a predetermined spacing from a doped region in the substrate is described to prevent or inhibit migration of dopant materials from an adjacent doped region through the barrier region. By implantation of group IV materials into a semiconductor substrate to a predetermined depth in excess of the depth of a doped region, a barrier region can be created in the semiconductor to prevent migration of the dopants from the doped region through the barrier region. The treatment of the single crystal substrate with the group IV material is carried out at a dosage and energy level sufficient to provide such a barrier region in the semiconductor substrate, but insufficient to result in amorphization (destruction) of the single crystal lattice of the semiconductor substrate.

    摘要: A process and resulting product are described for controlling the channeling and/or diffusion of a boron dopant in a P- region forming the lightly doped drain (LDD) region of a PMOS device in a single crystal semiconductor substrate, such as a silicon substrate. The channeling and/or diffusion of the boron dopant is controlled by implanting the region, prior to implantation with a boron dopant, with noble gas ions, such as argon ions, at a dosage at least equal to the subsequent dosage of the implanted boron dopant, but not exceeding an amount equivalent to the implantation of about 3.times.10.sup.14 argon ions/cm.sup.2 into a silicon substrate, whereby channeling and diffusion of the subsequently implanted boron dopant is inhibited without, however, amorphizing the semiconductor substrate.

    摘要: An electrostatic dust wand has a handle, a triboelectric charge generator, and a fibrous material. The triboelectric charge generator is coupled to the handle, and generates an electrostatic charge to attract dust particles to the cleaning implement. The fibrous material at least partially covers the triboelectric charge generator, to collect and to retain dust particles. The triboelectric charge generator has at least one movable member having a first triboelectric property, and an actuator for driving the at least one movable member. The electrostatic charge may be generated by movement of he at least one movable member against the fibrous material. Alternatively, or in addition, the electrostatic charge may be generated by relative movement of two members of the triboelectric charge generator against one another.

    摘要: A retrograde well in a CMOS device is formed by using a low energy ion implanter. Dopant atoms are implanted into a bare surface of the device's substrate, in a direction that is orthogonal to the surface of the substrate (for a substrate having a orientation). The well implant can be performed at an energy below 220 keV. Chained implants for a punch-through barrier in the retrograde well can be performed after the well implant. When the substrate is annealed, the punch-through barrier is activated at the same time as the retrograde well.

    摘要: Lifetime of a short-channel NMOS device is increased by modifying distributions of electrically active LDD dopant at boundaries of the device's LDD regions. The LDD dopant distributions are modified by implanting counter-dopants at the boundaries of the LDD regions. Group III counter-dopants such as boron and group IV elements such as silicon alter activation properties of the LDD dopant. The dopant distributions are modified at the device's n-junctions to reduce the maximum electric field displacement at an interface defined by the device's gate and substrate. The dopant distributions can be further modified to shape the n-junctions such that hot carriers are injected away from the gate.
