MACOM's KILOVOLT™ PIN diode series utilize modern semiconductor
and packaging technology that assures low loss, low
distortion, and reliable performance in multi-kilowatt
switch applications at frequencies as low as 1 MHz.
The PIN chips employed have low resistance, high
power dissipation and very high stand-off voltage
capability. KILOVOLT™ PIN diodes employ ultra high
resistively, long carrier lifetime, float zone material
onto which P+ and N+ regions are deposited using an
epitaxial process designed by MACOM's for high voltage PIN diodes. This process results in better preservation of the carrier lifetime and superior layer to layer interface when compared to a
conventional double diffused process. The processing
of the I-region width is tightly controlled using modern
lapping techniques. KILOVOLT™ PIN diode chips
utilize MACOM's proprietary Cermachip™ glass passivation.
The hard glass covers all exposed junction and intrinsic
surfaces. This results in a hermetically sealed, passivated
chip that has been used in many high reliability military and commercial programs.
