[DMANET] PhD positions at the Ecole des Mines de Saint-Etienne (site of Provence) / Modeling and optimization in Semiconductor Manufacturing

Two PhD positions (one industrial and one more academic within a
European project) are available at the Ecole des Mines de Saint-Etienne
(Gardanne, France) on semiconductor manufacturing related problems within
projects in cooperation with STMicroelectronics (in Rousset and in
Crolles), one of the worldwide leaders, and other partners.

The two topics are summarized below.
1. Industrial PhD thesis (CIFRE) With STMicroelectronics in Crolles
(France, 38).
Title : "Robust Management of Product Qualifications in Industry 4.0"
Short abstract: The objective of the thesis is to develop
methodologies and decision-support tools to deal with the low visibility
and high variability of product demands. The configuration of the
machines in the various production workshops is now managed according to
a short-term load plan. Nevertheless, recent events (sudden and
unexpected peaks) have clearly demonstrated the need to develop a
consistent approach for the qualification of machines. This thesis aims
at developing a static approach proposed by the EMSE, integrating the
anticipation and robustness aspects of demand forecasting. A method and
a tool should be proposed for the management of qualifications in all
the workshops of Crolles300.

The PhD thesis should include robust and stochastic discrete
2. PhD thesis within the European PRODUCTIVE 4.0 in Gardanne (France, 13).
Title: "Novel optimization approaches for global fab scheduling"
Short abstract: The fabrication of semiconductor devices is
probably the industrial process with the most complex process flows from
wafer fabrication through test and then assembly. To optimize the
agility of semiconductor manufacturing facilities and move toward
"Industry 4.0", new approaches should be developed and implemented.
Within the European project PRODUCTIVE 4.0, the objective of this thesis
on "Global fab scheduling" is to develop an approach using analytical
and simulation models to ensure consistency between fab production
control and scheduling at workshop level. The notion of of "yield
criticality" at product/step level will be integrated together with
equipment health, performance or risk criteria. A global factory
simulation model including models at lower (tool and workshop) levels
will be studied. Varying mix and toolset configurations and varying WIP
(Work-In-Process) management strategies will be considered and
evaluated. The approach will be validated on industrial data.

This thesis will be part of a large European project with multiple
industrial partners, including Infineon and STMicroelectronics. It will
include large-scale optimization, in combination with a simulation model
already developed but that could be extended.
The PhD theses will be conducted in cooperation with the research group
"Manufacturing Sciences and Logistics" of the Center of Microelectronics
in Provence (Ecole des Mines de Saint-Etienne), located in Gardanne
(South-East of France, between Aix-en-Provence and Marseille).

The PhD students will be located either in the site of Crolles (close to
Grenoble) of STMicroelectronics for the first topic and in Gardanne for
the second topic.

The positions are for three years and can start as early as June 2017
(exact date to be discussed).

Applicants must have a Master Degree (or equivalent) in Computer
Sciences, Applied Mathematics, Industrial Engineering or any related
discipline. Applicants should demonstrate good programming skills and
knowledge in combinatorial optimization. Experience on the development
of solution methods for planning or scheduling problems or/and in
simulation would be appreciated

Please send your application electronically (preferably as a single pdf
file) including a detailed curriculum vitae and examination results,
plus, if available, a list of reference letters and copies of diploma,
