Description and Applications
This device is a silicon glass PIN diode chip fabricated with
M/A-COM Tech Solutions patented HMIC process.
This 80μm I-region length device features six silicon
pedestals embedded in a low loss, low dispersion
glass. The diodes are formed on the top of a ped-
estal and connections to the backside of the device
are facilitated by making the pedestal sidewalls elec-
trically conductive. Selective backside metallization is ap-
plied producing a surface mount device. The topside
is fully encapsulated with silicon nitride and has an
additional polymer layer for scratch protection.
These protective coatings prevent damage to the
junction and the anode air-bridge during handling
and assembly. The vertical silicon diode topology
provides for a highly efficient heat transfer medium.
These surface mount devices are suitable for usage
in higher (3W avg.) incident power switches. Small
parasitic inductance and excellent RC constant
make these devices ideal for absorptive SPST, re-
flective SP2T switches, and attenuator circuits,
where higher P1db and power handling values are
required.
