The electronics industry in
Singapore
is divided into four
main categories that are also its best prospects:
-
Semiconductors and Disk Drives
-
Electronic Modules and Components
-
Photovoltaic Devices (solar cells)
-
Electronic Manufacturing Services and Peripherals
Introduction

Background
Singapore
's achievements in the electronics industry, according to the Singapore
Economic Development Board (EDB), include the following:

10% global market share for semiconductor wafer foundry output

Home to the world's top three wafer foundry companies

Home to the world's top three sub
-
contract assembly
-
and
-
test companies

Home to four of the world's top 10 fabless IC design companies

25% global market share for both printers and disk drives
Singapore's eminence in the electronics industry is evident in the quantity and
scope of facilities currently located in the country.
It is home to over 14
semiconductor wafer fabrication plants (including two 300 mm fabrication
plants), 20 assembly and test operations, and 40 IC design centres.
However,
many of the disk drive manufacturers have moved out to lower cost countries,
leading to less assembly and testing activity in Singapore.

Situation (Chem. Eng.)

Electronic materials processing by solid state chemistry and
physics is heavily researched by
US chemical engineers
, but more
so by chemists and physicists in the UK. In the US, whilst chemists
and physicist do this research, they are focused on the phenomena
rather than the applications and product design.

Specialization in Microelectronics

The specialisation is offered due to

the importance of the semiconductor industry to Singapore and the
region.

the role of chemical/process engineering in the wafer fab and
photovoltaic industry.

The
objectives
of the specialisation :

to provide an
orientation
for chemical engineering students to the
industry.

to enable
application
of the principles of chemical sciences and
engineering to the manufacturing operations in the wafer fab and
photovoltaic industry.

to provide the required
background and skills
to chemical engineers
to enable them to contribute to the wafer fab and photovoltaic
industry.

BN4404 Bioelectromechanical Systems
This module will provide students with background and basic knowledge of bioMEMS
and introduce some useful techniques. Students will have a basic understanding of the
principles, current state and prospects of bioMEMS and will be able to tackle simple
problems in bioMEMS using what they have learned. The module will focus on major
topics such as microfabrication technologies, micropatterning of biocompatible
materials, microengineering of biomolecules, cells and tissues, biochips, biosensors,
and the frontiers in bioMEMS.

Specialist Manpower Programme

Sponsored by the Economic Development Board (EDB) of Singapore

The SMP is a sponsorship programme for the 3rd and/or 4th year of the B.Eng.
programme in a Wafer Fabrication specialisation, and is open to students from ECE,
ME, and ChBE departments.
Students taking up the sponsorship are bonded to work
for the sponsoring company for 1 year.
120 sponsorships per year will be made
available to NUS students.

Sponsored students (selected by the sponsoring companies) will receive a stipend of
$540 per month during the 3
rd
and 4
th
year of study.

Upon graduation, the sponsored students are bonded to work with the company for 1
year.

What does a chemical engineer do?
Concerns of the chemical engineer:
Processes where materials undergo a required change in

composition

energy content

physical state
……with applications to useful ends
Specifically, processes in which „core elements‟ of chemical
engineering are important:

transport phenomena

equilibrium processes

rate processes

What does a chemical engineer do?
A chemical engineer is the one who

knows enough engineering to confuse the chemist

knows enough chemistry to confuse the draughtsman

knows enough mathematics to confuse the boss

knows enough electricity to confuse himself/herself

knows enough
microelectronics
to have more career
opportunities, and ……
i.e., is inherently trained for multidisciplinary work.
