DDR Memory bus termination SSTL Termination SHORT PRODUCT APPLICATION NOTE
The SWDDR1A-CSP is a high performance integrated Passive Device which provides
Series/Parallel terminations suitable for use in SSTL and DDR termination
applications. Sixteen Series/Parallel termination channels are provided
for a total of 32 integrated resistors. These resistors provide excellent
high frequency performance in excess of 3 GHz and are manufactured to an
absolute tolerance of ±1%. The Chip Scale Package provides an ultra small
footprint for this Integrated Passive Devices and provides minimal parasitics
compared toconventional packaging. Typical bumps inductance is less than
25pH. The large solder bumps and ceramic substrate allow for standard attachment
to laminate printed circuit boards without the use of underfill. The 4x9
Bump pattern is arranged for easy flow through routing on the pcb. 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. RESISTOR SPECIFICATIONS
