ELEG 450/650 - Spring 2001

Topic: Final Report due before noon Wednesday, 23 May.

Grading will be on how complete and clear your report is. It is worth 30 % of your final grade and is therefore important.

Include:

1. Processing parameters: be thorough, - include specifics not given in the typed lab handouts. For example: name the resist and developer types because these can vary semester to semester. Give enough detail so that the lab sessions can be reproduced precisely. Try to strike a good balance between sufficient detail, without belaboring standard lab practice such as using HF in plastic beakers and plastic, which is well known. A good guideline is to give information such that, along with the handouts, your colleagues could duplicate your projects.

Process subsections:

a. Lithography section- which resist, spin rpm, exposure.

b. Oxidation section- how long for each type, wet or dry

c. Diffusion - type of dopant sources, calculated junction depths.

d. Metal contact type and thickness.

2. Circuit electrical schematic (showing transistor symbols).

3. Logic diagram of your design circuit (showing gate symbols).

4. Truth table

5. Data: voltages and currents measured on the fabricated circuit: (specific numerical values to 2 significant figures) a. Individual processed transistor data - current, voltage; b. Verification of truth table giving voltage. Threshold voltages. Etc. This section is pivotal.

6. Estimate power dissipation by calculation using parameters given in class.

7. Estimate speed by calculation using parameters given in class.

8. Summary and conclusion - are the results of the circuit what you expected, and why. What was your goal and was it met?

Hints and grading criteria: be specific and inclusive, yet brief. Do not refer to data presented in previous lab reports, without giving the data here. Have your final report stand alone. But do not submit merely a collection of previous lab reports.

Would a technical reader (non-650) understand your project? Would you be proud of showing your report to a circuit processing engineer? (hint: a copy of you report would be a terrific item in your job hunting portfolio).
