Description and Applications
The MADS-002545-1307 Series Surmount
Silicon Schottky Cross-Over Quad Diodes are fabricated with the patented Heterolithic Microwave Integrated Circuit (HMIC) process. HMIC circuits consist of
Silicon pedestals which form diodes or via conductors embedded in a glass dielectric, which acts as the low dispersion, low loss, microstrip transmission medium. The combination of silicon and glass allows HMIC devices to have
excellent loss and power dissipation characteristics in a low
profile, reliable device.
These Surmount Schottky devices are excellent
choices for circuits requiring the small parasitics of a
beam lead device coupled with the superior mechanical performance of a chip. The Surmount structure employs very low
resistance silicon vias to connect the Schottky contacts to the
metalized mounting pads on the bottom surface of the
chip. These devices are reliable, repeatable, and a
lower cost performance solution to conventional devices. They have lower susceptibility to electrostatic
discharge than conventional beam lead Schottky diodes.

Equivalent Circuit
The multi-layer metallization employed in the fabrication of the
Surmount Schottky junctions includes a platinum diffusion barrier, which permits all devices to be subjected to a 16hour non-operating stabilization bake at 300°C.
The “ 0202 ” outline allows for Surface Mount placement and
multi- functional polarity orientations. The MADS-002545-1307
Series is recommended for use in microwave circuits through
Ku band frequencies for lower power applications such as mixers, sub-harmonic mixers, detectors and limiters. The HMIC
construction facilitates the direct replacement of more fragile
beam lead diodes with the corresponding Surmount diode,
which can be connected to a hard or soft substrate circuit with
solder.

Handling Procedures
All semiconductor chips should be handled with care
to avoid damage or contamination from perspiration
and skin oils. The use of plastic tipped tweezers or
vacuum pickups is strongly recommended for individual
components. The top surface of the die has a protective
polyimide coating to minimize damage.
The rugged construction of these Surmount devices
allows the use of standard handling and die attach
techniques. It is important to note that industry standard
electrostatic discharge (ESD) control is required at
all times, due to the sensitive nature of Schottky
junctions. Bulk handling should insure that abrasion
and mechanical shock are minimized.
Die Bonding
Die attach for these devices is made simple through
the use of surface mount die attach technology.
Mounting pads are conveniently located on the bottom
surface of these devices, and are opposite the active
junction. The devices are well suited for high
temperature solder attachment onto hard substrates.
80Au/20Sn and Sn63/Pb36 solders are
acceptable for usage.

1. Operation of this device above any one of these parameters
may cause permanent damage.
Die Bonding
For Hard substrates, we recommend utilizing a
vacuum tip and force of 60 to 100 grams applied
uniformly to the top surface of the device, using a
hot gas bonder with equal heat applied across the
bottom mounting pads of the device. When soldering
to soft substrates, it is recommended to use a
lead-tin interface at the circuit board mounting pads.
Position the die so that its mounting pads are
aligned with the circuit board mounting pads. Reflow
the solder paste by applying Equal heat to the circuit
at both die-mounting pads. The solder joint must Not
be made one at a time, creating un-equal heat flow
and thermal stress. Solder reflow should Not be
performed by causing heat to flow through the top
surface of the die. Since the HMIC glass is transparent, the
edges of the mounting pads can be visually inspected
through the die after die attach is completed.
