The apparatus serves for treating workpieces by means of a plasma torch in a gaseous, preferably in an inert gaseous atmosphere. For this purpose, there is provided a gas-tight container and, in the interior of the container, a plasma gun as well as a cooling member for cooling the treated workpiece by a gaseous cooling medium stream. The cooling medium is a gas circulating in a closed circuit. Thus, the the cooling gas can continuously used because heat is removed from the gas in a heat exchanger. A cooling operation can be realized in this way in temperature regions which are much higher than if liquified gas is used.

A method and apparatus is described for orienting samples for charged particle beam operations. A sample is attached to a probe with a major surface of the sample at a non-normal angle to the probe shaft, and the probe shaft is rotated to reorient the sample. The invention is particularly useful for preparing planar view TEM samples. The invention allows for a sample to be mounted to a TEM grid and thinning by an ion beam without removing the grid from the vacuum chamber for reorienting. In one embodiment, a probe oriented at an angle, such as 45 degrees, to the sample stage has a probe tip with a flat area oriented parallel at 45 degrees to the probe axis, that is, the flat area is parallel to the sample stage. The flat area of the probe tip is attached to the sample, and when the probe is rotated 180 degrees, the orientation of the sample changes by 90 degrees, from horizontal to vertical. The sample can then be attached to a vertically oriented TEM grid on a sample stage. The sample ...

A method for processing a substrate surface in a process chamber wherein during chemical or physical altering of the substrate surface a laser beam is projected inside the processing chamber and along a trajectory which does not contact the substrate surface in order to capture particles by means of the photophoretic effect, particles which would otherwise impinge upon and contaminate the substrate surface.

Focused ion beam processing

Номер: US4639301A

An apparatus is described which makes possible the precise sputter etching and imaging of insulating and other targets, using a finely focused beam of ions produced from a liquid metal ion source. This apparatus produces and controls a submicron beam of ions to precisely sputter etch the target. A beam of electrons directed on the target neutralizes the charge created by the incident ion beam. Imaging of the target surface and ultra-precise control of the etching process is achieved by monitoring the particles that are sputtered from the target surface.

Device for demonstration of rotation of free electrons in closed system

Номер: RU2666923C1

FIELD: physics.SUBSTANCE: invention relates to theoretical and experimental physics. In the method, a device for demonstrating the rotation of free electrons in a closed system contains a pair of toroidal permanent magnets facing each other with opposite magnetic poles, as well as a DC power supply. In the magnetic gap between the permanent magnets there is a hollow vacuum-evacuated glass disk with two semi-axes of its rotation, in the center of which there is a thermal cathode with a heating thread, electrically connected to the semi-axes and through a pair of sliding contacts with the source of the heating voltage of this filament of the thermal cathode. At the periphery of the glass disk, an annular anode is placed by fusing it into the glass of the disk, connected from the outside with a sliding contact. Also, the thermal cathode and the annular anode are connected via sliding contacts to a high voltage direct current source.EFFECT: technical result consists in verifying the lack of counteraction forces for the acting Lorentz forces that ensure the rotary motion of closed mechanical systems under the action of only internal forces.1 cl, 2 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 666 923 C1 (51) МПК G09B 23/18 (2006.01) H01J 37/02 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ На основании пункта 1 статьи 1366 части четвертой Гражданского кодекса Российской Федерации патентообладатель обязуется заключить договор об отчуждении патента на условиях, соответствующих установившейся практике, с любым гражданином Российской Федерации или российским юридическим лицом, кто первым изъявил такое желание и уведомил об этом патентообладателя и федеральный орган исполнительной власти по интеллектуальной собственности.

본 발명은 이온빔조사시의 기판표면의 대전(帶電)을 더욱 작게 억제하는 것을 그 과제로 한다. 이를 해결하기 위한 수단으로 기판(2)에 이온빔(14)을 조사하여 이온주입 등의 처리를 실시할 때 플라즈마 발생장치(20)로부터 방출시킨 플라즈마(30)를 기판(2) 근방에 공급하고, 이온빔조사에 따른 기판표면의 대전을 억제한다. 그 때 기판(2)에 조사되는 이온빔(14)의 빔전류를 I B , 플라즈마 발생장치(20)로부터 방출되는 플라즈마(30)안의 이온의 량을 나타내는 전류를 I I , 동 플라즈마(30)안의 전자량 나타내는 전자전류를 I E 로 했을 때 I E /I B 로 나타내는 비율을 1.8이상으로 유지하고 또한 I I /I E 로 나타내는 비율을 0.07이상 0.7이하로 유지한다. An object of the present invention is to further suppress the charging of the substrate surface during ion beam irradiation. As a means to solve this problem, when the ion beam 14 is irradiated onto the substrate 2 to perform ion implantation or the like, the plasma 30 emitted from the plasma generator 20 is supplied to the vicinity of the substrate 2, The charging of the substrate surface caused by the ion beam irradiation is suppressed. At that time, the beam current of the ion beam 14 irradiated onto the substrate 2 is I B , and the current representing the amount of ions in the plasma 30 emitted from the plasma generator 20 is I I , which is in the same plasma 30. When the electron current representing the electron quantity is set to I E , the ratio represented by I E / I B is maintained at 1.8 or more, and the ratio represented by I I / I E is maintained at 0.07 or more and 0.7 or less.

본 발명은 향상된 비임 중화기를 특징으로 하는 이온주입에 관한 것이다. 실린더형 전자소오스는 이온비임이 주입실에 들어오기전의 위치에서 이온비임을 둘러싼다. 전자소오스의 규칙적으로 공간을 둔 공동은 통전하여 전자를 방출하는 전선필라멘트를 포함한다. 전자는 이온비임의 영역을 통해 가속되고 실린더형 전자 지지대의 안쪽으로 마주한 벽과 충돌한다. 이로 인해 이온비임을 중화시켜 저에너지전자 방출을 한다. 이온화 가스를 전자방출면과 이온비임간의 영역에 주사하므로서 비임중화기 수행이 향상된다. The present invention is directed to ion implantation characterized by an improved beam neutralizer. The cylindrical electron source surrounds the ion beam at the position before the ion beam enters the injection chamber. The regularly spaced cavity of the electron source contains wire filaments which energize and emit electrons. Electrons are accelerated through the region of the ion beam and collide with the walls facing inwardly of the cylindrical electron support. This neutralizes the ion beam and emits low energy electrons. By performing the ionizing gas into the region between the electron emitting surface and the ion beam, the performance of the non-neutralizer is improved.

A charge control electrode emitting photoelectrons is disposed just above a wafer (sample) in parallel thereto, and the electrode has a through hole so that ultraviolet light can be irradiated to the wafer through the charge control electrode. Specifically, a metal plate which is formed in mesh or includes one or plural holes is used as the charge control electrode. By disposing the charge control electrode just above the sample in parallel thereto, when negative voltage is applied to the electrode, electric field approximately perpendicular to the wafer is generated. Therefore, photoelectrons are efficiently absorbed in the wafer. Also, by using the charge control electrode having approximately the same size as that of the wafer, charges on a whole surface of the wafer can be removed collectively and uniformly. Therefore, time required for the process can be reduced.

Ion Implantation Surface Charge Control Method and Apparatus Abstract An ion beam neutralizer. High energy electrons are directed through an ion beam neutralizing zone or region containing an ionizable gas. As the high energy electrons collide with the gas molecules, they ionize the gas molecules and produce low energy electrons which are trapped by a positively charged ion beam. As high energy electrons pass out of the neutralizing zone they are deflected back to the neutralizing zone by a cylindrical conductor biased to deflect the high energy electrons and an accelerating grid for accelerating the electrons back through the beam neutralizing zone.
