Filters
In order to minimize filter roll-off, we start with a quality, highly polished substrate and apply layers of metallization within tight tolerances. Our highly anisotropic ion beam etching process enables us to produce features down to 10 microns. Furthermore, the milling process yields a high consistency from circuit to circuit meaning that whether we produce 1 or 100,000 filters, each one will have consistent filter roll-off characteristics.

Schottky Barrier Bridge Quads
SemiGen’s Silicon Schottky Diodes are designed for applications through 40Ghz. The special process technology utilizes various metal schemes to provide excellent performance of Low, Medium, and High Barrier applications. The end result is a low resistance diode with tightly controlled capacitance which allows for optimum performance. Low conversation loss and superior TSS make these diodes ideal for detector / mixer applications with frequency ranges from S band to Ka band as well as modulators, lower power limiters and high speed switches.

Diode Submounts
Ultra-precise patterning of thin film metals on dielectrics with high thermal conductivity are used for diode submount applications. Via the acquisition of Ion Beam Milling, Inc., SemiGen is the industry leader for laser diode submount fabrication. As each application is different, we work with customers to develop a custom design that perfectly fits their requirements. We have experience producing circuits utilizing substrates of varying thicknesses with high thermal conductivity such as alumina (Al), aluminum nitride (AlN), and beryllium oxide (BeO). SemiGen can deliver laser diode submounts with or without Au/Sn pads depending on your needs.

Fixed Attenuator Pads
SemiGen RF/microwave fixed attenuator pads feature precise resistor films and superior metalization resulting in superior performance and consistency. Our advanced thin-film technology allows our parts to have full side wraps for SMT installation and a complete grounding backside for ease in attachment, as no ground bonding is requried. Top side contacts for the input and output make these ideal for standard RF/microwave assembly techniques. They are available as MIL PRF 38534 “H” & “K” space screened units. Custom values are easy to fabricate and design allowing users to design in a specific value of choice.

Inductor Coils
SemiGen's Inductor Coils are manufactured using our thin film process on quartz substrates. The precision photolithography and non-chemical etching process provides clean edges to assure uniformity from coil to coil. By using quartz and applying a polyimide coating we produce a device that eliminates the need for conformal coating or staking. Inductors can be epoxied down with nonconductive epoxy and the wire bonded for connection.
