A short design is required. Therefore, in addition to the above-mentioned requirements, it is desirable that the differential exhaust diaphragm and the objective limiting diaphragm can shorten the length of the charged particle optical system.
- FIG. 1 is an example of the block diagram of the charged particle device of this embodiment.
- the charged particle device 100 internally has a charged particle optical system including a charged particle source 101, an extraction electrode 102, an acceleration electrode 103, a condenser lens A 107, an objective limiting aperture 110, a differential exhaust aperture A 111, a valve 114 and an objective lens 116. It has a lens barrel and a stage 112 on which an object 113 for observation and analysis is placed. The object 113 is also referred to as a sample.
- the lens barrel has therein a vacuum chamber A105 evacuated by a vacuum evacuation pump A108 and a vacuum chamber B106 evacuated by a vacuum pump B109.
- the lens barrel is a structure having therein the charged particle optical system from the charged particle source 101 to the objective lens 116.
- the vacuum chamber B 106 includes the object 113 and the stage 112 in FIG. 1, the space in which the object 113 is placed is distinguished from the lens barrel as a sample chamber.
- the vacuum chamber B 106 may have an orifice for performing differential evacuation between the objective lens 116 and the object 113, and the charged particle optical system and the sample chamber may have different degrees of vacuum.
- the charged particle beam 104 is emitted from the charged particle source 101 by the effect of heat and / or the electric field of the extraction electrode 102. Then, the charged particle beam 104 emitted in a certain direction is accelerated or decelerated by the voltage applied to the accelerating electrode 103 and travels toward the object 113.
- the charged particle beam 104 that has passed through the accelerating electrode 103 is focused by a condenser lens A 107 disposed closer to the charged particle source 101 than the objective limiting stop 110. The focusing point at this time is called a crossover point A115.
- the operating state of the condenser lens is changed to move the crossover point A 115 on the optical axis, whereby the objective limiting diaphragm 110 disposed closer to the object 113 than the condenser lens A 107
- the beam diameter of the charged particle beam 104 to be irradiated that is, the current density of the charged particle beam 104 can be changed.
- the outer peripheral portion of the beam is blocked and only a predetermined diameter portion of the beam central portion is passed, so the beam current of the charged particle beam 104 passing through the objective limiting diaphragm according to the position of the crossover point A115. It can be adjusted.
- the objective limiting stop of this embodiment is disposed in the vacuum chamber A105. It is desirable that this objective limiting stop be of a structure capable of changing the hole diameter.
- the charged particle beam 104 that has passed through the objective limiting aperture 110 passes between the differential exhaust aperture A 111 and the valve 114, is focused on the object 113 by the objective lens 116, and is irradiated.
- the object 113 is placed on the stage 112 and can be moved, tilted or rotated in the X and Y directions, so that the charged particle beam 104 focused at an arbitrary position of the object 113 is irradiated.
- the charged particle optical system includes the charged particle source 101, the condenser lens A 107, the objective limiting diaphragm 110, etc., other lenses, electrodes, deflectors and detectors may be included, or a part of them.
- the configuration of the charged particle optical system is not limited to this.
- the electron beam is deflected by a deflector to scan the object with an electron beam, and secondary particles such as secondary electrons and reflected electrons obtained from the position irradiated with the electron beam Is detected by the detector, and an image of the object is generated by correlating the detection signal with the scanning position.
- the generated image of the object is displayed on a display unit such as a display.
- the charged particle beam device has a control unit (not shown) that controls the above-described members, and can make the above-described members be in a predetermined operation state by a control signal from the control unit.
- the control unit controls the amount of current supplied to the condenser lens A 107 to adjust the position of the crossover point A 115.
- the control unit may be provided with an input unit for instructing the operation state of each member.
- the processing executed by the control unit can be realized by either hardware or software.
- it can be realized by integrating a plurality of processing units to execute processing on a wiring board or in a semiconductor chip or package.
- it can be realized by installing a high-speed general purpose CPU in a computer and executing a program that executes desired arithmetic processing.
- control unit the input unit, the display unit, and the like may be connected to the charged particle beam device 100 through a network, and may be configured to communicate data as needed.
- a high vacuum on the order of 10 ⁇ 4 to 10 ⁇ 9 Pa is required in the atmosphere around the charged particle source 101.
- the required degree of vacuum depends on the type of charged particle source 101.
- the sample chamber in which the object 113 is placed is not required to have a degree of vacuum as high as that of the charged particle source 101.
- a differential evacuation throttle A111 is installed between the vacuum chamber A105 and the vacuum chamber B106, and the vacuum chamber A105 is evacuated by the higher vacuum pump A108. Do.
- the vacuum chamber B106 is evacuated by the vacuum pump B109 having a lower ultimate pressure.
- a differential pressure corresponding to the hole diameter of the differential evacuation throttle A is generated in the vacuum chamber A105 and the vacuum chamber B106, and the vacuum chamber A105 can be maintained at a higher degree of vacuum.
- the vacuum chamber A and the vacuum chamber B are connected through the differential evacuation throttle A.
- the vacuum pumps A and B may be configured by one vacuum pump, and the vacuum chamber A 105 and the vacuum chamber B 106 may be exhausted by two exhaust paths having different displacements.
- the vacuum chamber B 106 side needs to be opened to the atmosphere and exchanged in order to remove the object 113 from the sample chamber or replace it with another object.
- a valve 114 is installed between the vacuum chamber A 105 and the vacuum chamber B 106 so that the vacuum chamber A 105 side can maintain a high vacuum, and shuts off the vacuum chambers of each other. That is, when the charged particle beam 104 is irradiated to the object for observation, analysis, etc. by making the valve movable, the opening of the differential exhaust diaphragm A111 is opened, and then the observation, analysis is completed, and the charged particles are terminated.
- the differential exhaust throttle A 111 is closed by the valve 114 to close the hole of the differential exhaust throttle. If there is a load lock mechanism to replace the object 113, the valve 114 is not always necessary, but the vacuum chamber B106 where the object 113 enters can be opened to the atmosphere regardless of the degree of vacuum of the vacuum chamber A105. Is desirable.
- the vacuum chamber A 105 and the vacuum chamber B 106 defined here have a minimum vacuum chamber configuration, and each vacuum chamber is divided into two or more, and differential evacuation is further performed by providing a differential evacuation throttle A 111 between them. It can be a high performance charged particle device.
- the objective limiting aperture 110 may cause charge-up or, in the worst case, the aperture diameter may be narrowed and may be buried. In order to reduce this effect, the objective limiting diaphragm 110 is often heated and used by a heater. If the vacuum chamber disposed is opened to the atmosphere when the objective limiting aperture 110 is heated, oxidation is promoted by oxygen in the atmosphere to contaminate the objective limiting aperture 110.
- the sample when replacing a sample, the sample is used by being installed in the sample chamber via another vacuum chamber (not shown) adjacent to the vacuum chamber B, which is once called a load lock chamber. It was not assumed that the vacuum of B106 would deteriorate. Therefore, the size of the object 113 that can be introduced into the vacuum chamber B106 is limited by the load lock chamber, and the vacuum of the vacuum chamber B106 also needs to be maintained at a high degree of vacuum to some extent. Under this condition, the objective limiting stop was placed in the vacuum chamber B. For this reason, in the conventional charged particle beam apparatus, it was necessary to wait for the vacuum chamber to open to the atmosphere until the objective limiting stop 110 is cooled.
- the objective limiting diaphragm 110 is disposed inside the vacuum chamber A105. Even if the vacuum chamber B106 is open to the atmosphere, the chamber with the objective limiting diaphragm 110 (vacuum chamber A105) is kept at high vacuum, so the vacuum chamber B106 can be brought to the atmosphere while the objective limiting diaphragm is heated. Furthermore, by disposing the objective restriction diaphragm 110 closer to the charged particle source 101 side than the valve 114, the vacuum chamber B106 can be opened to the atmosphere without depending on the degree of vacuum of the vacuum chamber A105. As a result, the waiting time for replacing the object 113 can be significantly reduced.
- FIG. 2 is an enlarged view around the objective limiting diaphragm 110 of FIG.
- the crossover point A 115 moves up and down, and the amount of charged particles passing through the objective limiting diaphragm 110 increases or decreases. If the distance L1 from the condenser lens A107 to the crossover point A115 formed by the condenser lens A107 can be increased, the range for changing the amount of charged particles passing through the objective limiting diaphragm 110 can be made large. Therefore, conventionally, the objective limiting aperture 110 is provided on the side of the object 113 with respect to the valve 114.
- the differential exhaust aperture A111 disposed immediately on the object 113 side passes through the charged particle beam 104 passing through all conditions.
- the hole diameter should be such that it does not obstruct.
- the hole diameter of the differential evacuation throttle A 111 is preferably as small as possible. The shorter the objective limiting aperture 110 and the differential exhaust diaphragm A111 distance L2 between and is short, the hole diameter d 2 of the differential pumping aperture A111 may be reduced. Therefore, in FIG.
- the structure of the valve 114 is disposed closer to the object 113 than the differential exhaust throttle A111. Further, in terms of the arrangement of the objective limiting aperture 110, the differential exhaust aperture A111, and the valve 114, in other words, the differential exhaust aperture A111 is disposed closer to the object 113 than the object limiting aperture 110 and from the differential exhaust aperture A111.
- the valve 114 is disposed on the side of the object 113. That is, the valve 114, the differential exhaust diaphragm A 111, and the objective limiting diaphragm 110 are disposed in the order of proximity to the object 113. At this time, by arranging the object limiting diaphragm 110 as close as possible to the valve 114, it is possible to have a large range for changing the amount of charged particles.
- the distance L2 between the objective limiting aperture 110 and the differential exhaust aperture A111 is desirably shorter than 20 mm.
- valve 114 structure since the valve 114 structure is on the high pressure side, when the vacuum chamber B106 on the object 113 side is opened to the atmosphere, a vacuum leak does not easily occur on the vacuum chamber A105 side on the charged particle source 101 side. It has become.
- FIG. 3 shows, in the configuration of FIG. 1, a condenser lens B117 for controlling the opening angle of the charged particle beam 104 irradiated to the object 113, a differential exhaust diaphragm B118 for improving the differential exhaust capability, and a differential
- This is a charged particle device 200 having a vacuum chamber C121 partitioned by an exhaust throttle A111 and a differential exhaust throttle B118 and a vacuum pump C120 for independently evacuating the vacuum chamber C121.
- the opening angle of the charged particle beam 104 is controlled by adjusting the position of the crossover point B119 created by the condenser lens B117.
- description of the same parts as those of the first embodiment or the second embodiment will be omitted.
- the differential evacuation throttle B118 By disposing the differential evacuation throttle B118 closer to the object 113 than the differential evacuation throttle A111 and evacuating the vacuum chamber C121 with the vacuum pump C120, the differential evacuation capability from the charged particle source 101 to the object 113 becomes high.
- the degree of vacuum around the object 113 can be kept lower. It is desirable that the vacuum pump B109 and the vacuum pump C120 be independent of each other, and that the vacuum pump C120 has a higher evacuation capability than the vacuum pump B109.
- the vacuum pump B109 and the vacuum pump C120 may be the same vacuum pump connected by adjusting the evacuation conductance or the pump performance so that the evacuation speed is different.
- FIG. 4 is an enlarged view around the objective limiting diaphragm 110 of FIG.
- the diameter of the charged particle beam irradiated to the object 113 of the charged particle device 200 configured in FIG. 3 is affected by the lens aberration generated in the condenser lens B117. It gets bigger.
