A charged particle detecting device includes: a holding structure; a first charged particle detector at the terminal portion of the holding structure; a second charged particle detector at the terminal portion of the holding structure; a detector head at the terminal portion of the holding structure; and a first electrode which is transmissive for the first and second species of charged particles covering an entrance opening of the detector head.

Charged particle detecting device and charged particle beam system with same

The present disclosure relates to a gas field ion source having a gun housing, an electrically conductive gun can base attached to the gun housing, an inner tube mounted to the gun can base, the inner tube being made of an electrically isolating ceramic, an electrically conductive tip attached to the inner tube, an outer tube mounted to the gun can base, the outer tube being made of an electrically isolating ceramic, and an extractor electrode attached to the outer tube. The extractor electrode can have an opening for the passage of ions generated in proximity to the electrically conductive tip.

Charged particle beam system and method of operating a charged particle beam system

The present disclosure relates to a charged particle beam system comprising a charged particle beam source, a charged particle column, a sample chamber, a plurality of electrically powered devices arranged within or at either one of the charged particle column, the charged particle beam source and the sample chamber, and at least one first converter to convert an electrical AC voltage power into an electrical DC voltage. The first converter is positioned at a distance from either of the charged particle beam source, the charged particle column and the charged particle chamber, and all elements of the plurality of electrically powered devices, when operated during operation of the charged particle beam source, are configured to be exclusively powered by the DC voltage provided by the converter.

The present disclosure relates to a charged particle beam system, comprising a noble gas field ion beam source, a charged particle beam column, and a housing defining a first vacuum region and a second vacuum region. A noble gas field ion beam source is arranged within the first vacuum region. A first mechanical vacuum pump is functionally attached to the first vacuum region, an ion getter pump is attached to the charged particle beam column, and a gas supply is attached to the first vacuum region configured to supply a noble gas to the noble gas field ion beam source.

Ion sources, systems and methods are disclosed.

Ion sources, systems and methods

Disclosed are devices, systems, and methods are disclosed that include: (a) a first material layer positioned on a first surface of a support structure and configured to generate secondary electrons in response to incident charged particles that strike the first layer, the first layer including an aperture configured to permit a portion of the incident charged particles to pass through the aperture; and (b) a second material layer positioned on a second surface of the support structure and separated from the first layer by a distance of 0.5 cm or more, the second layer being configured to generate secondary electrons in response to charged particles that pass through the aperture and strike the second layer, where the device is a charged particle detector.

Charged particle detectors

Charged particle system are disclosed and include a first voltage source, a second voltage source electrically isolated from the first voltage source, a charged particle source electrically connected to the first voltage source, and an extractor electrically connected to the second voltage source. Methods relating to the charged particle systems are also disclosed.

Variable energy charged particle systems

A dual beam system includes an ion beam system and a scanning electron microscope with a magnetic objective lens. The ion beam system is adapted to operate optimally in the presence of the magnetic field from the SEM objective lens, so that the objective lens is not turned off during operation of the ion beam. An optional secondary particle detector and an optional charge neutralization flood gun are adapted to operate in the presence of the magnetic field. The magnetic objective lens is designed to have a constant heat signature, regardless of the strength of magnetic field being produced, so that the system does not need time to stabilize when the magnetic field is changed.

Dual beam system

Charged particles that are in transit through a deflection system when the beam is repositioned do not received the correct deflection force and are misdirected. By independently applying signals to the multiple stages of a deflection system, the number of misdirected particles during a pixel change is reduced.
