PROBLEM TO BE SOLVED: To provide an extraction electrode manipulator having reduced maintenance frequencies and reduced troubles. SOLUTION: The extraction electrode manipulator system includes a suppression electrode 210 supported by an inside support tube 248 of a support tube system coaxially arranged, a ground electrode 212 supported by an outside support tube 246 of the support tube system coaxially arranged, and a high voltage insulator ring 211 located at the distant end of the support tube system coaxially arranged to mechanically support the support tube system and serve as a high voltage vacuum feedthrough. As a result, the high voltage insulator ring 211 as an insulating stand-off is located at the distant end of the support tube system coaxially arranged near an ion source to mechanically support the inside support tube and serve as a high voltage vacuum feedthrough, thus reducing the possibility that vapor reaches the insulating surface of the insulator ring 211 to contaminate and cover it.

PROBLEM TO BE SOLVED: To provide an implantation system for implanting ions into a workpiece in a plurality of operation ranges, and to provide an implantation method. SOLUTION: A required dose amount of ions is provided and a spot ion beam 112 is formed from an ion source 108 and undergoes a mass spectrometry by a mass spectrograph 126. The ions are implanted into the workpiece either in a first mode or a second mode base on the required dose amount. An ion beam is scanned by a beam scanning system 128 arranged in a downstream of the mass spectrograph 126 and is parallelized by a parallelizer 130 arranged in a downstream of the beam scanning system 128. In the first mode, the workpiece 122 is scanned through the scanning ion beam at least in one dimension by a workpiece scanning system 167. In the second mode, the ion beam passes without scanning the beam scanning system 128 and the parallelizer 130 and the workpiece 122 is scanned through the spot ion beam 112 in two dimensions.

PROBLEM TO BE SOLVED: To provide a system, a method, and a device for determining an ion beam profile. SOLUTION: The system includes a measuring apparatus 140 placed along the path way of the ion beam 110, a driving mechanism 175, and a first plate 165 rotatably connected to the driving mechanism 175. The driving mechanism 175 is operable for rotating the first plate around a first axis in the ion beam path way, and selectively prevents the ion beam arriving to the measuring device. The device includes a second plate 193 rotatably connected to the driving mechanism. The driving mechanism is operable for rotating the second plate around the first axis in the ion beam independent from the rotation of the first plate. The driving mechanism selectively prevents the ion beam arriving to the device. The first plate and/or the second plate are/is possible to be moved parallel on a straight line in the ion beam.

PROBLEM TO BE SOLVED: To form a porous low-k dielectric to be used in a semiconductor device. SOLUTION: Processes for forming porous low-k dielectric materials from low-k dielectric films containing a porogen material include exposing the low-k dielectric film to ultraviolet radiation. The film is exposed to broadband ultraviolet radiation of less than 240 nm. In other embodiments, the low-k dielectric film is exposed to a first ultraviolet radiation pattern effective to increase a crosslinking density of the film matrix. At the same time, the low-k dielectric film maintains a concentration of the porogen material substantially the same before and after exposure to the first ultraviolet radiation pattern. The low-k dielectric film can be then processed to form a metal interconnect structure therein and subsequently exposed to a second ultraviolet radiation pattern effective to remove the porogen material from the low-k dielectrics film and form a porous low-k dielectric film.

PROBLEM TO BE SOLVED: To lengthen a maintenance period by decreasing deposition of spattering by ion bombardment at implantation. SOLUTION: A cooling trap 200 contains materials which adsorb depositing materials such as texture or non-texture aluminum, graphite, porous aluminum, silicon carbide or silicon carbide foam. The cooling trap 200 is placed under a Faraday flag assembly 100'. An open cup 212 comprises high temperature of an upper region 213, and comparatively low temperature of lower region 214. Further, the cup is cooled by a closed loop cooling system 210 which uses coolant. The surface of an open cup 220 has notches, and interlayer exfoliation of a film spatter 211 or deposition on other surface in the ion implantation chamber 22 is decreased by collecting a thin film on the trap surface 220.
