Abstract: A light beam emitted by a light source is projected through a collimator lens, a beam splitter and an objective on a sample having a laminated structure. The light beam reflected from the sample travels through the beam splitter to a detector and the detector provides a confocal signal. The detector provides an interference signal upon the reception of the reflected light beam and a reference light beam reflected by a reference mirror. The sample and the reference mirror are moved on the basis of the confocal signal and the interference signal, and the thickness and the refractive index of layer of the sample are determined on the basis of the respective displacements of the sample and the reference mirror.

Abstract: A method of forming metal lines in a patterned dielectric layer. First, a thin
(50Å-500Å ) metal layer of a group VB metal, preferably niobium, is formed on a
patterned dielectric layer. Next, an aluminum layer or an aluminum alloy layer is
formed on the thin niobium layer. The aluminum layer is preferably formed by
depositing a first thickness of collimated aluminum at low temperature followed
by high temperature deposition of an equal thickness of aluminum. The
aluminum layer is Chem-Mech polished (CMP) with an oxidizing acidic colloidal
alumina slurry to expose and oxidize the thin niobium liner which acts as a polish
stop. Then, the exposed thin niobium liner is removed using CMP. Alternatively,
instead of niobium, the liner may be a thin layer of a group VB metal or an alloy
thereof.

Abstract: Method and apparatus are disclosed for driving an
infrared-image-pickup (IIP) device such that device
temperature is maintained substantially constant to
reduce or eliminate noise when switching shutter speeds
or when switching between a non-electronic-shutter mode
and an electronic-shutter mode. The IIP device includes
photodetectors that store charge when exposed to infrared
light and includes transfer units, such as charged
coupled devices. The number of pseudo or dummy pulses
that are applied to the transfer units in a non-electronic-shutter
mode is substantially equal to the
number of pulses applied to the transfer units in an
electronic-shutter mode. Having the same number of
pulses allows the temperature of the IIP device to remain
substantially unchanged when switching between non-electronic-shutter
and electronic-shutter modes.
Similarly, the number of pulses is maintained
substantially constant at all shutter speeds so that
switching between shutter speeds does not result in
temperature changes and noise.
