SHORT PRODUCT APPLICATION NOTE
The SWRN1645 is a high performance Integrated Device designed to eliminate
trensmission line effects on high-speed lines on a TTL. TTL is a bus interface
covered by ANSI standard that allows for an input/output bus to connect small
computers with a variety of peripheral devices. Proper resistor termination
requires a resistor whose value closely matches the characteristic impedance
of the transmisision line. Thin film networks offer significant advantage over
thick film processes in terms of tighter absolute and ratio tolerances, lower noise,
lower Temperature Coefficient of Resistance, greater stability. They offer
superior high frequency performance with minimal parasitic inductance and
capacitance. Integrated thin film networks also offer the benefits of board space
savings, reduced assembly costs, and increased reliability with fewer components.
SEMICONDUCTOR-THIN FILM MANUFACTURING PROCESS DESCRIPTION
Integrated passive networks are manufactured using advanced thin film technologies
including ultra -stable and self passivating Tantalum Nitride resistors, gold interconnect
metallization and reliable MNOS capacitors to achieve excellent uniformity, performance
and reliability. Thin film resistor technology is the preferred solution for all applications that
require low noise, long term stability and excellent performance at very high frequencies.
Semiconwell employs proprietary thin film technologies for deposition of a wide range of
sheet resistance films from 1 W/sq to 10,000 W/sq. All Semiconwell's products are available
in die form and as KGD, known good die and are ideal for high reliability hybrid and multi
chip module applications. Besides thin film resistors, Semiconwell integrates capacitors,
Schottky diodes, Zener diodes and transistors. Integrated passive and active networks
are manufactured using Semiconwell's in house high reliability semiconductor manufacturing processes.
All semiconductor devices employ precision doping via ion implantation, silicon nitride junction passivation,
platinum silicided contacts and gold interconnect metallization for best performance and reliability.
MNOS capacitors and Tantalum Nitride resistors are easily integrated with Schottky diode
to provide complete standard and custom RCD solutions. In die form, these products
are ideal for hybrid and multi chip module applications. In packaged form, these
products are the best solution where space and weight are a concern.

Delivery for packaged Resistor networks standard products is 4-6
weeks ARO. Certain items may be available from stock. For standard
products available from stock, there is a minimum line item order of
$250.0. Inventory is periodically updated. For 2500pc or larger orders,
all surface mount packaged devices are shipped in tape on reel (T/R).
For smaller quantities, it may vary. Samples are available only for customers
that have issued firm orders pending qualification of product in a particular
application. On line Orders have to be verified, accepted and acknowledged
