A process for forming a porous nanoscale membrane is described. The process involves applying a nanoscale film to one side of a substrate, where the nanoscale film includes a semiconductor material; masking an opposite side of the substrate; etching the substrate, beginning from the masked opposite side of the substrate and continuing until a passage is formed through the substrate, thereby exposing the film on both sides thereof to form a membrane; and then simultaneously forming a plurality of randomly spaced pores in the membrane.

In a scanning electron microscope, an emitted primary electron beam is diverted by an angle of at least about 45 degrees prior to incidence with a specimen. The beam may be bent by a magnetic separator. The separator may also serve to deflect secondary electron and back scattered electrons. As the angle of emissions and reflections from the specimen is close to the angle of incidence, bending the primary electron beam prior to incidence, allows the electron source to be located so as not to obstruct the travel of emissions and reflections to suitable detectors.

To obtain data pertaining to the surface characteristics of a sample, a control method adjusts a tilted rastered E-beam to in SEM to a first/next tilt condition and navigates the SEM-beam to a sample site. The system performs a fine alignment step. Then the system scans a region of a sample to acquire a waveform. The system analyzes the waveform to determine the DESL value for each edge of interest. The system tests whether there is sufficient information available for each structural edge. If NO, the system repeats the above steps starting by changing the value of the tilt angle to acquire another waveform. If YES, the system determines the height and sidewall angles for each structural edge. Then the system reports the sidewall angle and the structure height for each edge of the structure under test. The system then corrects the critical dimension measurement determined from 0 degrees tilt scanning.
