GENERAL DIE INFORMATION SUBSTRATE THICKNESS [mils] DIE SIZE LxW [mils] Ceramic (Al2O3) 10±1 15x12±2 RESISTOR BONDING PADS BACKSIDE METAL The resistive material is high stability Tantalum Nitride with low temperature coefficient of resistance, <75ppm/°C typical. For Rsq<10Ω/sq and Rsq>500Ω/sq, the resistive material is proprietary. 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. The backside of the die is metallized with TiW/Au which is compatible with most die attaching methods. Other metallizations are available upon special request. All US Microwaves products are available in die form. Typical delivery for die products is 2-3 weeks ARO. For Custom designs, delivery is 3-4 weeks ARO. Certain items may be available from stock. Inventory is periodically updated. All devices for chip and wire applications are 100% tested, visual inspected and shipped in waffle packs (WP). CERAMIC THIN FILM RESISTORS DIE LAYOUT / MECHANICAL SPECIFICATIONS MICROWAVE CERAMIC SUBSTRATE THIN FILM RESISTORS USMRE1215 MODEL S Nsq = 45.5 CERAMIC THIN FILM RESISTORS CHIP MOUNT MICROWAVE CERAMIC SUBSTRATE THIN FILM RESISTORS USMRE1215 MODEL S thin film chip resistor mount CERAMIC THIN FILM RESISTORS ASSEMBLY PROCESS - SHORT APPLICATION NOTE Thin film chip resistors are designed for critical designs where space is at premium. The thin film chip resistors can be die attached to the PCB or to a base plate using AuSn or AuGe preforms. Since the thin film chip resistors do not have terminals, they have to be attached using gold wire via gap welding after the backside is soldered in place. Backside metallization for thin film chip resistors is Ti/Pt/Au which is also compatible with Sn solder. For the more common SnPb, a Ti/Ni/Au backside metallization should be requested.

 MICROWAVE CERAMIC SUBSTRATE THIN FILM RESISTORS USMRE1215 MODEL S

PRODUCT DESCRIPTION AND SHORT APPLICATION NOTE
USMRE1215 MODEL S, Ceramic (Al2O3) series of microwave thin film resistors is designed to be used in microwave hybrid circuits for biasing of active components. These devices can be used over the full military temperature range -55°C to +125°C. Quality and workmanship is per MIL-S-883. Level B. Devices are 100% tested, visual inspected and packaged in waffle packs. US Microwaves employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1 Ω/sq to 10,000Ω/sq. Resistors from 0.1Ω to x MΩ range are available.
The resistive material is high stability Tantalum Nitride with low temperature coefficient of resistance, <75ppm/°C typical.

TECHNOLOGY DESCRIPTION: SEMICONDUCTOR-THIN FILM MANUFACTURING
All thin film microwave products are manufactured using advanced semiconductors and 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 technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. US Microwaves employs proprietary thin film technologies for deposition of a wide range of resistive films with sheet resistance films from 1Ω/sq to 10,000Ω/sq. All US Microwaves products are available in die form and are ideal for high reliability hybrid and multi chip module applications.
All US Microwaves products are manufactured using GOLD CHIP TECHNOLOGY™ a trade mark of Semiconix Corporation.

Ceramic (Al2O3) 10±1 15x12±2
RESISTOR BONDING PADS BACKSIDE METAL
The resistive material is high stability Tantalum Nitride with low temperature coefficient of resistance, <75ppm/°C typical. For Rsq<10Ω/sq and Rsq>500Ω/sq, the resistive material is proprietary. 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. The backside of the die is metallized with TiW/Au which is compatible with most die attaching methods. Other metallizations are available upon special request.
All US Microwaves products are available in die form. Typical delivery for die products is 2-3 weeks ARO. For Custom designs, delivery is 3-4 weeks ARO. Certain items may be available from stock. Inventory is periodically updated. All devices for chip and wire applications are 100% tested, visual inspected and shipped in waffle packs (WP).

CERAMIC THIN FILM RESISTORS ASSEMBLY PROCESS - SHORT APPLICATION NOTE
Thin film chip resistors are designed for critical designs where space is at premium. The thin film chip resistors can be die attached to the PCB or to a base plate using AuSn or AuGe preforms. Since the thin film chip resistors do not have terminals, they have to be attached using gold wire via gap welding after the backside is soldered in place. Backside metallization for thin film chip resistors is Ti/Pt/Au which is also compatible with Sn solder. For the more common SnPb, a Ti/Ni/Au backside metallization should be requested.
