Deli Wang, Professor
Overview of Research Activities
Joined in 2004 after his postdoctoral research at Harvard Univ.
Current research revolves around rational growth of new nanomaterials (semiconductor nanowires and nanowire heterostructures); investigation of fundamental electronic, optical and optoelectronic properties of nanostructures; design and development of functional nanoelectronic and nanophotonic systems, for communications, sensing, information storage, biological detection and medicine.

1) Controlling the Growth and Transport Properties of III-V Semiconductor Nanowires for Electronic Applications
III-V semiconductor nanowires (NWs) are engineered one-dimensional structures with unusual electronic and optoelectronic properties that hold great promise for next generation nanoelectronic devices (ITRS roadmap).1 To realize their potential, full understanding of and control over nanowire growth, electronic, and optical properties are required.
Jeongwon Park, PhD Candidate
Materials Science and Engineering Program
2) Electrical Properties and Structure Analysis of Y-junction Carbon Nanotubes
Carbon nanotubes (CNTs) show promise for a new molecular electronics based technology due to unique electronic properties and extraordinary mechanical properties. CNTs can be synthesized to be either semiconducting or metallic. Consequently, they can be used in a wide variety of electronics including diodes, transistors, and high frequency devices.
Dr. Bin, Xiang, Postdoctoral Fellow
Electrical and Computer Engineering
3) The Growth of ZnO Nanowire Arrays & Potential Applications
We successfully synthesized high-quality p-type and n-type ZnO nanowire arrays using simple chemical vapor deposition method in a conventional tube furnace, where phosphorus pentoxide has been used as the dopant source in the p-type ZnO nanowire growth process.

Hybrids/MCMs/RF Modules all require a visual inspection step just prior to encapsulation or hermetic seal. This is a critical process step that requires a high degree of operator skill and understanding of what to look for and reject as part of the inspection process. This course defines the inspection criteria based on traditional Mil Spec documents in conjunction with industry accepted best commercial practices. Over 200 color photographs of actual production defects are reviewed and discussed in detail. The students are exposed to a variety of defects and how the defects relate to the materials and process flow. Inspection checklists are used to simply the criteria and focus on the major problem areas.
- Understand what to look for as part of a pre cap visual inspection
- Learn how to interpret and apply traditional Mil Spec visual inspection guidelines
The course is intended for quality assurance personnel, inspectors, lead operators and others responsible for inspection of the hardware prior to the final package sealing process.
Course Outline:
Hybrid Materials and Processing Overview
General Inspection Guidelines and Procedures
Visual Inspection Requirements Flowdown
- MIL-PRF-38534
- MIL-STD-883

How You Will Benefit:
After completing this course you will:
- Advance your understanding of the basic materials and processing steps used in the assembly of Hybrids, Microcircuits and RF/MMIC Modules.
- Know what you’re looking at and what constitutes a “reject” in the production flow along with the technical rationale to support the decision.
- Be able to explain to others visual defects that result from the basic manufacturing processes: i.e. wirebond, component attach, thick and thin film processing etc.
- Learn how to interpret and apply the visual inspection criteria contained in the "Workmanship Standards for Hybrids, Microcircuits and RF/MMIC Modules” 2002 Edition*
Who Should Attend:
This course is a must for process engineers, design engineers, manufacturing engineers and senior technicians. Inspectors and experienced operators looking to broaden their knowledge base and understanding of visual inspection criteria would also benefit. The course is also suited for newly assigned engineers and QA personnel looking to learn the basic terminology and key concepts vital to the manufacturing floor. Trained instructors with years of industry experience deliver the material in a straightforward and easy to understand format.
About this Course:
Most companies struggle to introduce new lines and waste countless manhours and resources resolving old problems on the manufacturing floor. Much of this waste is directly tied to the knowledge and training level of the responsible individuals. This course is designed teach the fundamental materials and processes used in microelectronics manufacturing and develop an understanding of the relevant visual inspection criteria. “Knowing what to do” is the first step towards lower costs, improved quality and faster throughput. Multimedia powerpoint presentations and video clips introduce the basics in a classroom setting.
Seminar Instructor:
Thomas J Green has over twenty five years of experience in the microelectronics industry at Lockheed Martin Astro Space and USAF Rome Laboratories and as an Adjunct Professor at the National Training Center for Microelectronics. During that time period he was a Staff engineer responsible for the materials and manufacturing processes used in building custom high reliability space qualified microcircuits (Hybrids, MCMs and RF modules) for military and commercial communication satellites. Tom has demonstrated expertise in wirebonding, component attach, and seam sealing processes. He has conducted and analyzed numerous statistically designed experiments, which increased first past yield, reduced costs and improved product quality. At Rome Labs he worked as a senior reliability engineer and analyzed component failures from AF avionic equipment along with providing technical support for a variety of Mil specs and standards (e.g. MIL-PRF-38534 and MIL-STD-883). Tom is an active member of the IMAPS (International Microelectronics and Packaging Society) at both the regional and national levels and serves on the IMAPS National Technical Program Committee. Tom has a Masters degree in Industrial Engineering and a B.S. in Metallurgy and Material Science from Lehigh University. He's published numerous technical papers and in recent years has completed many successful in plant consulting projects.

French Chapter SIP-SOC Technical Meeting, CAEN, May 24 ^
Top
For its 2006 regional meeting, IMAPS France organised, last May in Grenoble, an international workshop on the packaging solutions for system integration. The compared benefits and limitations of System In a Package (SIP) and System On a Chip (SOC) were emphasised and the main semiconductor manufacturers in Europe presented roadmaps for the implementation of their preferred solutions.
The success of the 2006 event incited IMAPS France to keep the same topic, for the 2007 meeting, with an application oriented approach. The workshop will be held, on May 24, in Caen in the frame of a partnership with NXP the former semiconductor branch of Philips.
After the registration of the participants, in the NXP facilities, our partners will present the company and their own SIP/SOC strategy. Then, several industrial actors will disclose their experience returns and the resulting impact on the development of new products, in different market areas including medical, automotive, smart card and wireless systems. They will explain as well how those technologies help to fit in with emerging social needs as assistance, security or identification.
In addition, demonstrations of CAD tools, a poster session and, in the afternoon, the visit of several laboratories or industrial sites will be proposed to the participants according to one’s preference.
For registration or information:
Please contact Florence Vireton at the IMAPS France office, imaps.france@imapsfrance.org
