Small Signal RF PIN Diode Chips for Hybrid Integrated Circuits Technical Data HPND-0001 HPND-0002 Features Description • Thermocompression/ Thermosonically Bondable These PIN/NIP diode chips are specifically designed for hybrid applications requiring thermosonic or thermocompression bonding techniques. The top metallization is a layer of gold for a tarnish free surface that allows either thermosonic or thermocompression bonding techniques. The bottom metallization is also gold, suitable for epoxy or eutectic die attach method. • Ideal for Hybrid Integrated Circuits • Gold Metallization • Silicon Nitride Passivation • Uniform Electrical Characteristics • Batch Matched Versions Available • Planar Construction Applications These small signal, general purpose PIN/NIP diode chips are optimized for various analog and digital applications such as switches, digital phase shifters, pulse and amplitude modulators, limiters, leveling, and attenuating.

Storage Devices should be stored in a dry nitrogen purged dessicator or equivalent. 2. Cleaning If required, surface contamination may be removed with electronic grade solvents. Typical solvents, such as freon (T.F. or T.M.C.), acetone, deionized water, and methanol, or their locally approved equivalents, can be used singularly or in combinations. Typical cleaning times per solvent are one to three minutes. DI water and methanol should be used (in that order) in the final cleans. Final drying can be accomplished by placing the cleaned dice on clean filter paper and drying with an infrared lamp for 5-10 minutes. Acids such as hydrofluoric (HF), nitric (HNO3), and hydrochloric (HCl) should not be used. The effects of cleaning methods/ solutions should be verified on small samples prior to submitting the entire lot. Following cleaning, dice should be either used in assembly (typically within a few hours) or stored in clean containers in a reducing atmosphere or a vacuum chamber. 3. Die Attach a. Eutectic Eutectic die attach can be accomplished by “scrubbing” the die with/without a preform on the header to combine with the silicon in the die. Temperature is approximately 400°C, with heating times of 5-10 seconds. (Note–times and temperature utilized may vary depending on the type, composition, and heat capacity of the header or substrate used.) This method is recommended for the HPND-000X series. b. Epoxy For epoxy die-attach, conductive silver-filled epoxies are recommended. This method can be used for all Agilent PIN chips. 4. Wire Bonding Either ultrasonic, thermosonic or thermocompression bonding techniques can be employed. Suggested wire is pure gold, 0.7 to 1.5 mil diameter. www.semiconductor.agilent.com Data subject to change. Copyright © 1999 Agilent Technologies Obsoletes 5954-2108 5965-9143E (11/99)
