In high power applications, temperature coefficient of resistance and long term stability have to be the best available. 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.

GENERAL DIE INFORMATION Substrate Thickness [mils] Size [mils] Bonding Pads Backside metal Beryllium Oxide (BeO) 40±3 LLxWW±2 min. [W-2]x4 mils. Backside of the die is metallized and connected to one of the pads, with standard Ti/Pt/Au compatible with Au-Sn, Au-Ge or silver filled conductive epoxy. Single wrap around resistors are available with soldable or weldable terminations. Custom metallization is available for special orders. 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).

INSTANT QUOTE US Microwaves P/N Quantity E-mail ORDERING: Order on line at: http://www.usmicrowaves.com/porder.htm. A copy of the order along with an order confirmation receipt is issued instantly for all orders placed on line. On line Orders have to be verified, accepted and acknowledged by US Microwaves sales department in writing before, becoming non cancelable binding contracts. DELIVERY: Typical delivery for die products packaged in waffle packs is 2-4 weeks ARO. For Custom designs, delivery is 3-5 weeks ARO. Certain items may be available from stock with delivery up to 1 week. SHIPPING/PACKAGING: All devices for chip and wire applications are 100% tested, visual inspected and shipped in waffle packs (WP). For larger orders,>10k pc, devices can be shipped on film frame. For smaller quantities, it may vary. For high volume automated assembly, devices may be supplied as 4" wafers 100% tested, inked and diced on expanded film frame (FF). SAMPLES: Samples are available only for customers that have issued firm orders pending qualification of product in a particular application. GUARANTEED SUPPLY!
