Patent ID: 7297950

Claim:
A method of manufacturing a transmission electron microscope (TEM) specimen, comprising: preparing a preliminary specimen; and, forming a specimen by forming a dimple region on a surface portion of the preliminary specimen, and ion milling the preliminary specimen having the dimple region to form an ion-milling region within the dimple region, wherein preparing the preliminary specimen comprises: cutting a first and a second patterned wafer, cutting a first, a second, a third, and a fourth dummy wafer; forming the first face of the first patterned wafer on the first face of the second patterned wafer; forming the first, second, third, and fourth dummy wafers on second faces opposite the first faces of first and second patterned wafers to form a stacked specimen; slicing the stacked specimen in a direction substantially perpendicular to the first faces of the first and second patterned wafers to form a sliced specimen; punching the sliced specimen to form a circular specimen; and grinding the circular specimen to form the preliminary specimen.
