Description
The MA4E2500L SurMount series diodes are silicon low
barrier Schottky monolithic chip devices fabricated with
the Heterolithic Microwave Integrated Circuit (HMIC)
process. HMIC circuits consist of silicon pedestals, which
may form diodes or conductors, embedded in a glass
dielectric, which is used as the microstrip medium. The
combination of silicon and glass allows HMIC devices to
have excellent power handling and electrical perfor-
mance in a small rugged chip.
The SurMount Schottky devices are excellent choices for
circuits where the minimal parasitics of a beam lead
structure are required, but the mechanical fragility of a
beam lead is a liability. The SurMount chip structure
employs very low resistance silicon vias to connect the
Schottky contacts to the metalized mounting pads on the
bottom surface of the chip without using wirebonds.
These devices are low cost, rugged and reliable. They
have lower susceptibility to electrostatic discharge than
beam lead Schottky diodes. They are optionally available
with JANTX or MIL-S-883 Element 5008 equivalent
screening, and are suitable for space applications.
The multi-layer metalization employed in the fabrication
of the SurMount chip Schottky junctions includes a plat-
inum diffusion barrier, which permits all devices to be
subjected to a 16 hour non-operating stabilization bake
at 300°C.
The available congurations for the MA4E2500L series of
silicon low barrier SurMount chip Schottky devices
include single diodes, anti-parallel pairs, ring quads,
cross-over ring quads and series tees.
