CMC Microsystems
  • An organization with a 25-year history of
    stimulating RD
  • Discovery (leading to publications) and
  • Innovation (leading to products)
  • Involving micro- and nano-scale technologies
  • Through delivery of research infrastructure
    (tools, IP, technology, assembly and fabrication
    process, packaging, test equipment and services)
  • A path to commercialization

CMC enables and enhances the
competitiveness of Canadian industry and
researchers through innovation in the development
and application of microsystems.

Microsystems
  • Microsystems are comprised of a number of
    technologies integrated together with embedded
    intelligence and wireless network connectivity,
    to achieve the smallest, lowest power, highest
    performance solutions to a wide variety of
    problems
  • CMC supports development of microsystems by
    providing infrastructure and deliverables for
    Design, Make, and Test

Design for Integration
  • Integration constraints should be compensated in
    design stage
  • Constraints include inter-component functionality
    and manufacturing decisions
  • Functional constraints
  • Signal conditioning
  • Signal energy conversion
  • Manufacturing constraints
  • Material properties electrical, mechanical,
    thermal, chemical, biological
  • Fabrication process etching process, deposition
    process, surface/bulk post processing
  • Assembly Flip chip, Interposer, Through Silicon
    Via
  • Packaging consider parasitics, cavity size,
    bonding arrangement and pitch
  • Decision of monolithic and/or hybrid integration
    determines emphasis of constraints on final device

Proof of Concept Environment (PCE)
  • CMC standardized environments for microsystem
    development, characterization and validation
  • Incorporates platform technology, and development
    system modules, including packaging, assembly,
    and planar chip-scale technologies
  • Interoperable system, hybrid and monolithic
    integration technologies
  • User-configurable modules (useful for design of
    devices and of systems)
  • Means of providing embedded software support in a
    defined architecture
  • Pre-validated components for easy
    integration/customization
  • Reference designs
  • CAD tools for modeling components at the system
    level with the PCE, as well as controlling the
    operation of the physical system

11
PCE Example MEMS/FPGA Platform
  • Bench-top, rapid development platform for
    MEMS-based microsystems
  • Incorporates application development with custom
    MEMS devices (co-design of MEMS and
    microelectronics/ESW)
  • Intelligence sensing/actuation
  • Feedback loop control, signal processing
  • Once validated, can lead to miniaturization of
    complete device

Conclusion
  • Integration constraints must be considered in
    design phase of microsystems development
  • Design for Integration considers functional
    interoperability (design), physical
    implementation (make) and validation (test)
    issues in design phase
  • Proof of Concept Environments provide framework
    for Design for Integration
