SYSTEM TO INSPECT, MODIFY OR ANALYZE A REGION OF INTEREST OF A SAMPLE BY CHARGED PARTICLES, SET OF SYSTEMS TO INSPECT, MODIFY OR ANALYZE A REGION OF INTEREST OF A SAMPLE AND METHOD TO INSPECT, MODIFY OR ANALYZE A REGION OF INTEREST OF A SAMPLE BY CHARGED PARTICLES
20220260508 · 2022-08-18 ·

A system inspects, modifies or analyzes a region of interest of a sample via charged particles. A detector device of the system produces a pixel image having horizontal and vertical pixel resolutions. A charged particle deflection device produces a scanning charged particle beam in a scanning region. The deflection device has horizontal and vertical deflection units controlled by a digital to analog converter having a digital resolution larger than the horizontal pixel resolution and/or the vertical pixel resolution. An operator control interface of the system selects an assignment between respective image pixels of a desired pixel image and digital inputs of the DAC to produce horizontal and/or vertical deflection signals to guide the charged particle beam to the location of the respective image pixel. A reliable image of a sample can be obtained even when there is zooming or panning within an accessible region of the sample.

Redundant parallel positioning table device

A redundant positioning table device with six or fewer degrees of freedom having four modular legs extended from a base to a table, each legs being with three levels and the same types of joints. In one embodiment, the bottom joint is planar and active, the middle joint is prismatic and passive, and the top joint is spherical and passive. In another embodiment, the bottom joint is prismatic and passive, the middle joint is planar and active, and the top joint is spherical and passive. Fewer than six degrees of freedom is achieved by reducing the number of degrees of freedom of designated joints.

Defect Inspection Device and Defect Inspection Method
20220107280 · 2022-04-07 ·

Provided is a quantification method for evaluating the quality of a sample on the basis of a mirror electron image acquired by a mirror electron microscope. In this invention, a mirror electron image is expressed numerically through counting of the brightness values of each pixel composing the mirror electron image, the creation of a brightness histogram, and the calculation, from the distribution of the brightness histogram, of a standard deviation. If brightness contrast is formed on the mirror electron image by, for example, a scratch on or latent damage in a sample, because the brightness values of the pixels will fluctuate, there will be more variation in the brightness values than in an image obtained from a satisfactory sample with no defects, and this will result in the brightness values of the mirror electron image having a larger standard deviation. The standard deviation indicates the variation in the brightness calculated from the mirror electron image and essentially represents the degree of defect contrast in the sample. This value can be used as a basis for simply evaluating the quality of a sample while eliminating subjectivity and ambiguity.
