AZ 9260 thick film photoresist
AZ® 9260 thick film photoresist is designed for the more demanding higher-resolution thick resist requirements. It provides high-resolution with superior aspect ratios, as well as wide focus and exposure latitude and good sidewall profiles. AZ® 9260 photoresisti is available for a film thicknesses up to 24 µm.
Critical dimension resolutions range from < 1 µm lines and spaces at a film thickness of 4.6 µm, to 3.5 µm lines and spaces at a film thickness of 24 µm on silicon using today's standard broadband exposure tools. Aspect ratios of 5 - 7 can be achieved.
Under the guidance of leading thin-film recording head manufacturers, AZ® 9260 photoresist is optimized for both coil plating and top pole recording head applications.
Sensitivity to both h- and i-line makes AZ® 9260 photoresist capable for both broadband and i-line steppers.
Recommended developers are inorganicbased upon potassium hydroxide. The preferred developer is AZ® 400K Developer 1:4, a buffered developer designed to maximize bath life and process stability. For integrated circuit applications, TMAH developers such as AZ® 826 MIF developer can be used.

AZ 520D
AZ® PC 520 D is a cost-effective coating for the
protection of device surfaces during operations such as
back-lap or backside etch.
It is based on Novolak resin, has a blue colour for easy
inspection and is resistant to most etchants. The thickness of
this coating is 4,6 µm at 4000 rpm spin speed.

AZ 4999
AZ® 4999 is a spray coating dedicated
highly transparent photoresist tailored to excel on
special spray coating equipment (e.g. SUSS Delta
AltaSpray) where it provides defect free and conformal
coatings on devices with severe topography.
Thick (several to several tens of microns) and uniform
resist coatings are obtained on topography such as
V-grooves and trenches with optimum coverage of sharp
edges.
There is no accumulation of resist in trenches. The use
of AZ® 4999 photoresist enables high
reproducibility in volume production applications.

TI Spray
The TI Spray Photoresist is specially designed for the
application in the so called “image reversal technology”
for:
- subsequent lift-off of deposited layers
- wet chemical treatment in HF containing etching
solutions
- direct mesa grooving.
The viscosity enables a direct use in spray coating
equipment for a target thickness of 1 to 10 µm. The
typical aspect ratio of the structured features
achievable is in the range of 1.6 .. 2.0.
This technical data sheet intends to give you a
guide-line for process parameters for various
applications. However, the optimum values for e.g.
exposure dose, or development depend on the individual
equipment and need to be adjusted on each individual
demand.

PL 177
AZ® PL 177 is a positive tone liquid photoresist
for the application in various coating techniques,
especially for printed circuit boards manufacturing. AZ® PL 177 can be used in all those places, where
layouts are directly to be copied onto and subsequently
transferred into a substrate by etching, plating,
sputtering and related processes.
The essential features of AZ® PL 177 include:
-
high resolution potential
-
good drying behaviour
-
aqueous-alkaline processability
-
halogen free coating solvent
-
possibility of multiple exposure (selective
plating process) light or bright day light should be
avoided
storability of coated substrates
-
blue coloured for easy inspection
PL 177 can be applied by dip coating. By
dilution with suitable solvents PL 177 can be adjusted
to also meet the viscosity and drying requirements of
other coating techniques (spray coating, roller coating,
spin coating). PL 177 is resistant towards acidic and
ammoniacal etchants as well as acidic and neutral
plating baths.
The final removal of the temporary resist layer, the
stripping, is done with low concentrated bases. PL 177
is used in the manufacturing of printed circuit boards,
multilayer inner flexible boards and in chemical milling.

AZ Aquatar (TARC)
AZ® Aquatar® is a top layer anti-reflective coating for
use with g- and i-line. AQUATAR® acts like an optical
coating at the interface photoresist/air and improves
image contrast.
Multiple reflections within the photoresist are also
suppressed, the result is generally a reduction of the
amplitude of the swing curve to 1/3rd. Application is
very simple: it is just spun on top of the photoresist,
no additional bake cycle is required and the standard
development cycle removes it.
This simple process reduces linewidth variation over
topography significantly, however does not suppress
reflective notching.

AZ Barli (BARC)
AZ® BARLi®- II is a bottom antireflective layer
coating for use on highly reflective surfaces in the
semiconductor industry. It is designed to work with
positive photoresists and is optimized for i-line
exposure tools. Upon completion of the lithographic
process, AZ® BARLi® - II is patterned in a dry-etch
process.
AZ® BARLi®-II coating material is formulated in
photoresist-compatible solvents to simplify the EBR
process and to be both environmental and user friendly.
We recommend AZ® EBR 70/30 for best performance.
AZ® BARLi® - II is tailor-made to yield the
near-optimum values for refractive indices (n and k) for
i-line lithography, which ensures minimum reflectivity
and maximum swing reduction for photoresist layers.
Composed of highly absorptive polymer-bound dyes,
this material provides excellent coating uniformity and
step coverage.
AZ® BARLi® - II shows high etch selectivity (comparable
to AZ® BARLi® ) and high thermal stability up to
230°C. It does not show intermixing with photoresist.
AZ® BARLi® - II is available in two thickness
grades, 900 A and 2000 A, in order to provide optimum
film thickness for the first and the second swing
minimum respectively at about 3000 rpm spin speed.
