Prerequisites

It is recommended to have passed the subjects of the three previous courses, especially those related to the areas of physics, engineering and electronics.

Objectives and Contextualisation

The objective of the module is to present the techniques and methods that exist of manufacture at a micro and nanometric scale, so that the student will be capable of defining an appropriate sequence of processes for the realization of any type of device or functional structure. The content is focused on the manufacture of structures and functional devices, and not on the obtaining of materials. There will be practical and varied examples of fabrication of nanometric structures and devices (nanomechanical structures, graphene-based devices, nanosensors, photonic devices, micro / nano fluidic, etc.). An introduction to the operation and execution of processes in a Clean Room will also be carried out.

Content

The subject is divided into four main blocks:

Module 1. Planar technology (10 h.T, 5 h.P)

The main processes of planar technology are described individually and the general aspects of micro / nano electronics technology are presented, as well as their evolution (miniaturization)

Introduction to planar technology: concept, waffers, sequence of processes, etc.
Individual technological processes: deposition (PVD and CVD), engravings (dry and wet), thermal processes, implantation, lithography.
Integration of processes, CMOS technology.
Evolution and limits of micro / nano electronics

Module 2. Nanolithography and "nanopatterning" (8 h.T, 4 h.P)

Lithography and nanopatronization techniques are described for the definition of nanostructures and nanodevices in surfaces. Examples of the current state of the art are presented.

Advanced optical lithography
Litrography by electron beam
Lithograph by ion beam
Nanoimprint lithography
Nanofabrication through SPMs
Other nanolithographies

Module 3 Nanofabrication "bottom-up" (6h.T)

We describe methods for performing nanostructures and devices based on a "bottom-up" approach, based on the assembly of individual nanometric elements to build structures and functional devices.

Self assembly and guided self assembly.
Structures and devices based on nanofiles and nanotubes
Structures and devices based on nanoparticles
DNA Origami
Other methods of chemical and electrochemical manufacturing

Module 4 Practical work on nanofabrication

The student is introduced to the principles of operation of a Clean Room and to the methodology of design of masks and micro-chips. Due to the limitations imposed by the Covid-19 some strictly face-to-face session may not be possible (i.e. CNM clean room visit).

  •      Design of a mask with a dedicated software. (two sessions)
  •      Optical observation of the photolithography produced using the mask that the student has designed (one session).
  •      Observation with electron microscope of bottom-up structures.
  •      Guided tour of the clean room of the National Center for Microelectronics.

In addition, 5 hours of seminars have been planned with researchers specializing in nanofabrication, subject to the restrictions imposed by Covid-19. The number ofseminars will be a maximum of 5, but the final number will depend on the evolution of the Covid-19.

Methodology

Teaching will consist on 24 hours of theory lectures, 9 hours of problems and 15 hours of laboratory practices. In addition, 5 hours of seminar sessions are reserved to complete any aspect of the subject. The attending to these sessions personally or at a distance will depend on the Covid-19 situation.

Practices: The practical sessions and their corresponding reports will be carried out in groups of a maximum of two students. Groups formed by more than two students will not be accepted. The delivery of the reports will be governed by a deadline that will be communicated after having done the practice, via virtual campus.

Extra exercises: During the course, extra exercises may be given to the students that must be done out of the teaching hours and which will be evaluable.

Seminars: During the course there will be a maximum of five seminars given by researchers working in the field of micro and nanofabrication, aimed at presenting to the student the world of research, beyond the academic vision that is given to the course. Attendance to this seminar is obligatory to be able to be evaluated of the whole course. These seminars could be face-to-face or remote.
 

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

There will be the following evaluation activities:

Two partial exams (theory and problems), one at the mid-term and the other at the end, with a weight under the final qualification of 70% (35% each). Attendance to these partial exams is mandatory to be able to access to the recovery exam.

Reports corresponding to laboratory practices with a weight on the final qualification of 25%. This note will be taken into account for the final evaluation provided that the student exceeds the qualification of 4.5 as an average of the two partials or as a qualification of the recovery exam.

NOTE: Attendance at the practical sessions and the delivery of the corresponding report are a mandatory condition for the student to be evaluated.

Exercises about theoretical classes and seminar work: with a weight on the final qualification of 5%

NOTE: Attendance at the seminars is mandatory for the student to be evaluated.

Exam (theory and problems) for recovery: Attendance to the recovery exam will be recommended if you have obtained a qualification of less than 5 in one of the two partial examinations. The contents referring to the first partial and the second will be assessed separately. This allows presentation to the recovery of a partial or total contents of the subject. Final qualification of the exams (70% of the final subject qualification) will be the averaging between the two parts of the subject, choosing for each part the best qualification between the partial exam and the recovery exam.
