The rapid atomic layer deposition (RAD) process module
from Genus boosts ALD deposition rates to ~100 Å/min,
more than five times that of conventional ALD. The new
ALD chamber on the StrataGem platform reduces precursor exposure
time at the wafer surface and uses purge steps as short as 0.2 seconds,
delivering a mass-transport-dependent reaction with linear growth
using trimethylaluminum and water ALD chemistry. The module’s
stoichiometric films have excellent electrical characteristics with
good conformality and uniformity. The module addreses the need for
thicker conformal films (up to 500 Å) in semiconductors. Information: www.genus.com.

ILS Technology’s eCentre Hosted allows
fabs and OEMs to rent the use of an e-diagnostics application suite
on a tool-by-tool basis. The main hardware and software
framework is located in a secure hosting hub. The hub connects to
scribing fabs and OEMs with a minimal on-site support framework.
Using the latest version of eCentre, the system includes Flexible
Security Wrapper, which improves e-diagnostics security from a “connection
approved” to a “connection and context approved” format, and Data Collection Plan Manager (DCPM), which can change
data collection plans dynamically. The company has hubs in the United
States and Europe and plans to add one in Asia. Information: www.ilstechnology.com.
SurfaceWave technology from Philips Advanced Metrology
has been shown to provide rapid on-line measurement of copper
overburden thickness to new-generation platers. With the
new metrology function, plating characteristics can be adjusted
to compensate for changes in patterns and structures. The technology
can measure copper thickness in a small spot on a patterned wafer,
allowing IC manufacturers to optimize process conditions and keep
them under control. It is well suited for the copper overburden
application because it provides noncontact and nondestructive measurements
of the thickness and uniformity of copper and low-k dielectric features.
It can also measure associated metals such as tungsten, tantalum,
and tantalum nitride on SiO2 and low-k dielectrics. Information:

Wafer Foundry Services has opened an Internet-based
wafer foundry services marketplace. The technical and business-oriented
electronic marketplace gives semiconductor companies a single Web
location that can evaluate the offereings from many wafer foundries
to support their unique needs. Using the site, customers
can issue one request for quote to many vendors simultaneously,
simplifying the process of finding a manufacturing partner.
The Web site has three charter member foundry partners: 1st Silicon,
with manufacturing facilities in Malaysia; ZMD Foundry Division,
with facilities in Germany; and Tower Semiconductor, with facilities
in Israel. Information: www.waferquote.com.
EpiTUNE II in situ metrology systems, based on Luxtron’s Ripple technology, are being shipped on Aixtron MOCVD reactors. The system is a standard feature on all Aixtron
Planetary Reactors for production of gallium nitride (GaN)–based
optical devices. It provides precise control of challenging processes
such as GaN-based blue lasers, LEDs, and laser diodes. In
addition to measuring true surface temperature, the real-time monitoring
tool provides simultaneous reflectivity measurements of film-growth
characteristics. Ripple technology offers good precision
in temperature measurements over a range of 400° to 1600°C,
making the EpiTUNE II suitable for GaN, gallium arsenide, indium
phosphide, and other III-V applications. Information: luxtron.com, www.aixtron.com.

A six-page, full-color flow switch guide from Fluid Components
International is a quick reference tool on switch applications
and products for use in gas, liquid, and slurry environments. With
a sensor design that has no moving parts and no orifices to plug
or foul, the switches offer accurate, low-maintenance measurement
over a wide range. Their fully temperature-compensated
sensor design ensures long-term drift-free measurement and correct,
repeatable switch actuation. Switch output selections include single
relay, dual relays, open collector, and/or linearized analog.
