SHORT PRODUCT APPLICATION NOTE
The SWRN1646 is a high performance Integrated Device designed to
eliminate trensmission line effects on high-speed lines on a SCSI (Small Computer Systems Interface).
SCSI 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 diodes 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.

The bonding pads of the resistors are 3µm thick, 99.99% electroplated gold with a
TiW barrier that withstands 30 min at 400°C in air without loss of adhesion.
Resistive material is ultra stable TaN with low TCR < 75ppm/°C typical. For Rsq< 10W/sq and Rsq>500W/sq,
the resistive material is proprietary. Power rating/resistor max 100mW for R< 1KW and 25mW for R>1KW.
Standard tolerance is ±5%. Backside of the die is metallized with standard Si/Au
compatible with eutectic and epoxy die attach. Custom metallizations are available
upon special request for die products only.
