To attain very low capacitance to ground, these chip resistors are manufactured on quartz substrates and do not have backside metallization. These devices can be used over the full military temperature range -55°C to +125°C. Quality and workmanship is per MIL-STD-883. 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 W/sq to 10,000 W/sq. Custom lab kits are available: RQ3000T25 Lab kit 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 1W/sq to 10,000W/sq. All US Microwaves products are available in die form and are ideal for high reliability hybrid and multi chip module applications.

GENERAL DIE INFORMATION SubstrateThickness (mils)Die size (mils)ResistorBonding padsBackside metal SiO2 - Quartz 25±130 x 30 ±2The resistive material is high stability Tantalum Nitride with low temperature coefficient of resistance, <75ppm/°C typical. For Rsq<10W/sq and Rsq>500W/sq, the resistive material is proprietary.The bonding pads of the resistors are min 4x4 mils, 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 NOT metallized. Standard TiW/Au or other custom 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). For high volume automated assembly, MTR chip resistors (5% and 10% tolerance only) are supplied as 4" wafers 100% tested, inked and diced on expanded film frame (FF).
