2D
height distribution of a microelectronics pad including rounded
bumps
a) Height distribution
of a microelectronic pad of 700 x 500 µm² size. The false-color
bar exhibits the maximum height of the rounded bumps being around
90 µm.
b) Enlarged
top surface of one bump. The colors represent the amount of reflected
signal (red is plenty, blue is little).
3D
topography from
squared mini bumps
Detail 3D topography
of the surface of squared bumps at 15 µm height. The false
colors exhibit the reflected signal (red is plenty, blue is little).
Acquired with the complete system SemDex 310.
Corresponding 1D profile from 2 adjacent squared bumps.
CCD
Camera option
The SemDex 310,
311 and 110 can be equipped with a CCD camera as option built into
the corresponding sensor heads. The field-of-view is 1 mm2 at approx.
500 x 500 pixels.
Surface
roughness profile of a mini bump
Roughness profile
on top of a bump at 15 ìm height. The roughness was evaluated
to be Rz = 44.8 nm (Ra = 13.2 nm). Acquired with the complete system
SemDex 310.
Focussing
is automatically performed. Software features permit the selection
of points, lines or areas of interest to be inspected.
