Study of
a Thermal Transducer in an SOI CMOS Process for
Electrical Isolation
This study deals with SOI CMOS-compatible
electrical isolation. This research involves the
study of thermal signals as a medium to achieve
that isolation. This proposal describes the efforts
surrounding a thermal transducer as part of the
electrical isolation system. The proposed effort
involves the simulation and modeling of a thermal
transducer that converts an electrical signal
to a thermal signal, propagates the thermal signal
and then converts it back to an electrical signal.
The research team at the University
of Arkansas (U of A) will take proposed transducer
designs developed with JPL and simulate them using
Medici and/or Taurus-Device, finite element device-level
simulators capable of performing 1, 2 or 3-D simulations
of electro thermal interactions. As part of this
study, the effects of modifying the design of
the so-called thermal lens will be examined. The
thermal lens is that portion of the thermal transducer
that propagates the thermal signal and “focuses”
it onto a device that will convert the thermal
signal back to electrical. Methods of quickly
cooling the thermal transducer in an attempt to
improve the thermal recovery time thus allowing
faster operation will also be simulated. The initial
goals have been expressed as a 1 ms propagation
delay, which would meet the performance requirements
of the I2L buss. It is likely that the research
team at the U of A will be involved in alternative
designs for the thermal transducer as simulations
reveal the performance of the early proposed designs.
