Abstract

A device and method for cleaving a sample includes: creating an indentation on a top surface of the sample by applying a downward force along a vertical axis, the axis arranging perpendicularly to the top surface of the sample; providing a breaking pin and arranging the breaking pin under the sample to touch the bottom surface of the sample at a position that is directly opposite from the indentation; and, applying a downward force on the sample by providing a left side and right side breaker pin wherein the downward force comprises a left-side downward force extended through the left-side breaker pin and right-side downward force through the right side breaker pin, further the pins that provide the left-side and right-side downward force are disposed on a breaker bar and arranged to be on opposite sides of a vertical axis that extends through the indentation on the top surface.

Claims12

Dependent claims

A method of cleaving a sample comprising:

creating an indentation on the top surface of the sample by extending an indenter arranged on a vertical axis toward the top surface of the sample whereby a diamond tip of the indenter causes a defect in the sample and retracting the indenter along the vertical axis after the indentation is made on the sample;
adjusting a depth of the indenter along the vertical axis to provide a user variable downward force of the tip on the sample;
providing a breaking pin and arranging the breaking pin under the sample coincident to a bottom surface of the sample at a position that is directly opposite from the indentation on the top surface;
selecting a cleaving bar movable up and down parallel to the vertical axis, the cleaving bar comprising a first pin and a second pin and contacting with the first pin the top surface of the sample on one side of the indentation and contacting the second pin against the top surface of the sample on an opposite side of the indentation and whereby the cleaving bar moves independent of the indenter;
and
moving the first and second pins toward the breaking pin.

3 more elements

A method of cleaving a sample comprising:

providing a cleaving device comprising a stage horizontally disposed on a housing body, the stage having a substantially flat top and a knob for adjusting the stage horizontally in the x-direction with sub-micron precision independent of the substantially flat top of the stage and a breaking pin mounted on the housing body adapted to arrange under the sample and a cleaving bar disposed on the housing body and being operable along a vertical axis from a first retracted position to a second contacting position, the cleaving bar further comprising a left side breaker pin arranged on a bottom surface of the cleaving bar and a right side breaker pin on the bottom surface wherein the left and right side pins are disposed on opposite sides of the cleaving bar in relationship to the vertical axis;
placing the sample on the stage;
adjusting the sample horizontally in the x-direction via the stage;
and
cleaving the sample using the cleaving bar.
