Abstract
A method of examining a specimen comprising the steps of providing transmission electron microscope apparatus, mounting a specimen in a vacuum chamber of focused ion beam apparatus, isolating a site of the specimen with the focused ion beam apparatus in the vacuum chamber, and with the site located in the vacuum chamber, examining the site with the transmission electron microscope apparatus.
Claims16
An examination method comprising the steps of:
- locating a specimen and a holder in a substantial vacuum, the holder having tines separated by a gap;
- forming a membrane of the specimen with focused ion beam apparatus;
- moving the holder toward the membrane until the tines engage and adhere to the membrane with at least part of the membrane spanning the gap between the tines;
- moving the holder to move the membrane away from the specimen and to a position in line with transmission electron microscope apparatus;
- and
- examining the part of the membrane substantially along the gap with the transmission electron microscope apparatus.
An examination method comprising the steps of:
- locating a membrane and a holder in a substantial vacuum, the holder having tines separated by a gap;
- moving the holder toward the membrane until the tines engage and adhere to the membrane with at least part of the membrane spanning the gap between the tines;
- moving the holder to move the membrane to a position in line with transmission electron microscope apparatus;
- and
- examining the part of the membrane located substantially along the gap with the transmission electron microscope apparatus.
A method of preparing a specimen for transmission electron microscope examination comprising the steps of:
- locating a specimen and a holder in a substantial vacuum, the holder having tines separated by a gap;
- forming a membrane of the specimen with focused ion beam apparatus;
- moving the holder toward the membrane until the tines engage and adhere to the membrane with at least part of the membrane spanning the gap between the tines;
- and
- moving the holder to move the membrane away from the specimen and to locate the part of the membrane extending along the gap at a position in line with transmission electron microscope apparatus.
A method of preparing a specimen for transmission electron microscope examination comprising the steps of:
- locating a membrane and a holder in a substantial vacuum, the holder having tines separated by a gap;
- moving the holder toward the membrane until the tines engage and adhere to the membrane with at least part of the membrane spanning the gap between the tines;
- and
- moving the holder to locate the part of the membrane along the gap at a position in line with transmission electron microscope apparatus.
An examination method comprising the steps of:
- locating a specimen and a holder in a substantial vacuum, the holder including a controlled adhesion mechanism;
- forming a membrane of the specimen with focused ion beam apparatus;
- moving the holder toward the membrane until the holder engages and adheres to the membrane, the controlled adhesion mechanism for providing a controlled adhesion between the holder and the membrane;
- moving the holder to move the membrane away from the specimen and to a position in line with transmission electron microscope apparatus;
- and
- with the membrane held by the holder, examining the membrane with the transmission electron microscope apparatus.
