520/530/580.495 Microfabrication Lab

520.773 Advanced Topics in Fabrication and Microengineering

Class Presentation

In this course we are learning the basis of fabrication technologies within a context of a laboratory that has limited scope and facilities. We have a contact mask aligner, a photoresist spinner, an oxidation furnace, and a thermal evaporator as well as basic chemical setups for wet etching. However we need to broaden our horizons about what is possible to do and what the state of the art is. The following papers discuss  both processing improvements in fabrication  and integration  as well as different devices with applications in biology/medicine.

i) J.M. Blain Christen and A.G. Andreou, “Design, fabrication and testing of a hybrid CMOS/PDMS microsystem for cell culture and incubation,” IEEE Transactions on Biomedical Circuits and Systems, Vol.1, No. 1, pp. 2-14, April 2007 (Invited Paper) (pdf)

ii) T. H. Wang, Y. H. Peng, C. Y. Zhang, P. K. Wong, C. M. Ho, " Single-molecule tracing on a fluidic microchip for quantitative detection of low-abundance nucleic acids," Journal of the American Chemical Society 127 (15): 5354-5359 2005 (pdf)

Read ONE of the above two papers and prepare a presentation for the class. In preparing your presentation keep in mind the resources of the lab at Hopkins and discuss the possibility of doing the project in the facilities available at Johns Hopkins. Work in groups of 2 or 3 (teams that you had in the lab sections). You will have 5 minutes for your presentation with an additional 2 minutes for questions. Your presentation should be prepared using a presentation software package (Powerpoint, Freelance e.t.c) and converted to a PDF file. Bring your presentation on  a floppy or a memory stick so that we can do an electronic presentation in the class. Your presentation should contain no more than 8 slides WITHOUT color background (you can use color figures but do not use fancy background schemes).

The presentation should include:

  1. Names and title of  the  project (1 slide)
  2. Introduction and literature survey (1 slide)
  3. Fabrication (1 or 2 slides)
  4. Characterization and Testing (1 slide)
  5. Conclusions (1 slide)
  6. Extra slides with results from testing your device that you fabricated in the lab (1 or 2 slides).

Please hand in: i) an electronic AND ii) hardcopy version of your presentation
