    摘要: In an ion beam apparatus a structure for controlling the surface potential of the target comprising an electron source adjacent to the beam for providing electrons to the beam and means between the target and source for inhibiting rectilinear radiations, i.e., electron and other particle and photon radiations between said source and said target. This prevents heating of the target by the electron source and cross-contamination between the source and the target. A further structure is provided for the measurement of the ion beam current while controlling said surface potential of the target which includes: walls adjacent to and electrically insulated from the target and surrounding the beam whereby the walls and target provide a Faraday Cage, means for introducing variable quantities of electrons into the beam within the Faraday Cage, means for measuring the target current, means for combining and measuring the target and wall currents to provide said ion beam current measurement and means for varying the quantities of introduced electrons to control the target current and thereby the target surface potential.

    摘要: Process and apparatus for use in extracting negative ions from a plasma which is particularly useful in reactive ion etching of metals, silicon and oxides and nitrides of silicon in the manufacture of semiconductor devices. A magnetic field is employed in the apparatus and, herein, is created by a novel grid, through which negative ions pass to a surface, such as one to be etched, while free electrons are prevented from passing through the grid and out of the plasma. The novel process utilizes negative ions which have a large fraction in the atomic state.

    摘要: A plurality of magnetic pole pieces are arranged around the external wall of a high temperature plasma confining structure. The pole pieces are positioned between permanent magnets spaced from one another and the confining structure by distances calculated to produce a minimum field toward the center of the structure with an effective containing field around the periphery of the structure. The magnets and the pole pieces are cooled. An odd number of poles are employed such that the missing pole appears as a virtual pole at the extraction slit used for forming an ion beam for ion implantation. The resulting small package multipole plasma containment functions to provide higher beam current, longer source lifetime, higher voltage stability and reduces maintenance and cleaning operations, with the permanent magnets protected from high temperature and corrosive gases.

    摘要: A plasma enhancing baffle plate is employed in conjunction with the anode of an RIE system to provide uniform silicon etching. The baffle plate is conductively coupled to and provided in relatively close proximity to the anode to form a constricted chamber region between anode and baffle plate. With the constricted chamber open to the RIE chamber through aperture means in the baffle plate the total surface area of the anode is increased, such that when the system is biased to operate in an RIE mode an increase in the generation of neutral etching species is effected. Various aperture arrangements may be employed to provide different patterns of neutral etching species generation, in accordance with the peculiar characteristics of the system employed.

    摘要: Watercraft hulls and parts thereof are disclosed which improve hydrodynamic performance for yachts, sailboards, and other craft. Drag at the transition from displacement mode to planing mode may be reduced to be the same or less than the minimum drag experienced in planing mode. Exemplary embodiments may include a bow with a center planing surface and tunnels to either side. The bow tunnels may each end in a step. At least part of the center planing surface may be cambered. A spoiler and/or interceptor may be provided at an aft end of a camber of a planing surface. For some hulls, the bow is followed by a main lift surface which is followed by a back lift surface (from stem to stern). In the back lift surface behind the main lift surface, a tunnel surface may be provided to add longitudinal stability.

    摘要: A winglet in a planing hull for sailboards with longitudinal length at least three times its transverse width, or a top slot that covers at least half the winglet area, and a forward slot and or a top slot, which allows dynamic lift from both the top and bottom surface of the winglet when the board is traveling at a transition speed between displacement mode and planing mode, but at high planing speed it does not normally have lift from the top surface of the winglet. This winglet may have a camber/slope step on the planing surface. In addition the transverse section of the nose of the hull can have the shape of an upside down wing.
