mixers - sub harmonic - chip 9 HMC1058 v00.1212 gaas mmic sub harmonic mixer, 71 - 86 ghz mounting & bonding techniques for millimeterwave gaas mmics the die should be attached directly to the ground plane eutectically or with conductive epoxy (see hmc general handling, mounting, bonding note). 50 ohm microstrip transmission lines on 0.127mm (5 mil) thick alumina thin flm substrates are recommended for bringing rf to and from the chip (figure 1). one way to accomplish this is to attach the 0.102mm (4 mil) thick die to a 0.150mm (6 mil) thick molybdenum heat spreader (moly- tab) which is then attached to the ground plane (figure 2). microstrip substrates should be located as close to the die as possible in order to minimize bond wire length. typical die-to-substrate spacing is 0.076mm to 0.152 mm (3 to 6 mils). handling precautions follow these precautions to avoid permanent damage. storage: all bare die are placed in either waffle or gel based esd protec - tive containers, and then sealed in an esd protective bag for shipment. once the sealed esd protective bag has been opened, all die should be stored in a dry nitrogen environment. cleanliness: handle the chips in a clean environment. do not attempt to clean the chip using liquid cleaning systems. static sensitivity: follow esd precautions to protect against > 250 v esd strikes. transients: suppress instrument and bias supply transients while bias is applied. use shielded signal and bias cables to minimize inductive pick- up. general handling: handle the chip along the edges with a vacuum collet or with a sharp pair of bent tweezers. the surface of the chip may have fragile air bridges and should not be touched with vacuum collet, tweezers, or fngers. mounting the chip is back-metallized and can be die mounted with ausn eutectic preforms or with electrically conductive epoxy. the mounting surface should be clean and fat. eutectic die attach: a 80/20 gold tin preform is recommended with a work surface temperature of 255 c and a tool temperature of 265 c. when hot 90/10 nitrogen/hydrogen gas is applied, tool tip temperature should be 290 c. do not expose the chip to a temperature greater than 320 c for more than 20 seconds. no more than 3 seconds of scrubbing should be required for attachment. epoxy die attach: apply a minimum amount of epoxy to the mounting surface so that a thin epoxy fllet is observed around the perimeter of the chip once it is placed into position. cure epoxy per the manufacturers schedule. wire bonding ball or wedge bond with 0.025mm (1 mil) diameter pure gold wire. thermosonic wirebonding with a nominal stage temperature of 150 c and a ball bonding force of 40 to 50 grams or wedge bonding force of 18 to 22 grams is recom - mended. use the minimum level of ultrasonic energy to achieve reliable wirebonds. wirebonds should be started on the chip and terminated on the package or substrate. all bonds should be as short as possible <0.31mm (12 mils). 0.102mm (0.004?) thick gaas mmic wire bond rf ground plane 0.127mm (0.005?) thick alumina thin film substrate 0.076mm (0.003?) figure 1. 0.102mm (0.004?) thick gaas mmic wire bond rf ground plane 0.254mm (0.010?) thick alumina thin film substrate 0.076mm (0.003?) figure 2. 0.150mm (0.005?) thick moly tab for price, delivery and to place orders: hittite microwave corporation, 2 elizabeth drive, chelmsford, ma 01824 phone: 978-250-3343 fax: 978-250-3373 order on-line at www.hittite.com application support: phone: 978-250-3343 or apps@hittite.com
