Outline

• Introduction to semiconductor manufacturing equipment– Product complexity (number of potential articles)– Nature of supply chain – Sector’s control over the supply chain

• Substances in articles – SEMI understanding and questions about ECJ ruling:

– How to enforce definition of article? – Questions that have been raised– Proposals that have been floated

• Restrictions on substances in articles – PFOA– How SEMI uses PFOA in articles– SEMI concerns about proposed restriction

• Sustainable industry engagement in regulatory initiatives

About semiconductor manufacturing

• manufacturing @ the nanometer scale -a human hair is 100K times wider than a 7nm transistor• controlled cleanroom environment • 2nd most R&D intensive industry (2015 EU Innovation Scoreboard) • EU Key Enabling Technology (EU, 2013)

Exponential technological advances

The Electronics Supply Chain

Semiconductor manufacturing equipment @ a glance

• High mix• Low volume• Highly customized • High Value • Long service life – sold onto many users • Subject to EU regulations (e.g. Machinery Directive, REACH)• Large scale stationary industrial tools within large scale fixed

installations• Subject to industry-wide standards• Operate under strict conditions (cleanroom environment)

Semiconductor Manufacturing Equipment – HIGH MIX

• 10 000s – 100 000s of direct components in one product.

• Many more indirect components/articles.

• Countless ‘homogeneous layers’

Industry standards

• Drafted, voted and reviewed by industry • Cooperation across the supply chain• Regularly reviewed to reflect new technological and regulatory developments

Semiconductor manufacturing is global

The nature of the supply chain

Substances in articles

14

15

What is an article?

Insulated electric cable: • PVC tube is produced separately and pulled over wire-> cable is composed of 2 articles• PVC is mixture poured over wire -> cable is 1 article

Question: is there a test to show how the cable was manufactured?

More questions:• Sheet composed of carbon fibers fixed together by a resin mixture ->

is each carbon fiber is an article?• Example of what is not an article? (i.e. shape etc. resulting from

manufacturing process is not more important than chemical properties)

Applying ECJ ruling: How Many Articles in this Tea Kettle?

A corrosion resistant paint is needed between a bracket, and the frame to which the bracket attaches with screws. 1. The paint is 19% w/w of a candidate list substance (CLS) – 1 gram of paint is

needed in the assembly which dries to contain 0.2 grams of the CLS. Some non-CLS substances are lost from the paint due to evaporation.

2. The bracket weighs 50 grams. 3. The frame weighs 1,500 grams.4. The 2 screws weight 5 grams each (= 10 grams)

Case A - The necessary amount of paint is applied to the bracket and left to dry. The resulting article is 0.2/50.2 (or 0.4% w/w) CLS. When the painted bracket is then assembled to the frame, it is a complex product containing an article exceeding the CLS threshold.

Case B - The necessary amount of paint is applied to the frame and left to dry. The resulting article is 0.2/1,500.2 (or 0.013 % w/w) CLS. When the unpainted bracket is assembled to the painted frame, it is a complex product without any article exceeding the CLS threshold.

The order of manufacturing is important

18

Issues raised by ECJ ruling

• Common definition of what is an article• Common understanding of number of articles in a complex product

>> must rely on information provided through the supply chain• Communication: supply chains are global - EU REACH is regional• Complying with information requirements while addressing IP/CBI

issues• Common understanding of most appropriate format for

communicating information• Compliance for used equipment

19

Various stakeholders’ reactions to ECJ ruling • Enforcement moratorium• REACH impact on competitiveness• Supply chain due diligence• ECHA-hosted website on prioritized components• ECHA-hosted component database • Proportionality • Cut-off limits• Peanut principle• Standardised information communication format• Information re end-of-life/waste stage and overlap with other EU

legislation• Impact on restrictions (Annex XVII) to ‘articles and any part thereof’?

Restrictions on substances in articles - PFOA

20

21

Use of PFOA in articles in semiconductor manufacturing equipmentMay be used in components/sub-components: • Chemical containers• Tubing • Gaskets• Ductwork • Filtration systems• Insulated conductors• Small mechanical assemblies• Various coatings

>>> Supply chain communication still ongoing to identify potential use and presence

Development and validation process

SEMI concerns over PFOA restriction in articles

• Testing methods not available for all uses at time of restriction proposal

• Reliance on supply chain communication • SEMI request for 10-year derogation

– Got 5 years– possibility for review?

• Articles or any parts thereof – complete ban but what about degradation telomers?

• Potential of industry PFOA-free certification systems

Sustainable management of regulatory initiatives

Global regulatory landscape

26

Overview of regulatory initiatives impacting SEMI members - 2015• REACH – PFOA, its salts and PFOA-related substances • POP Convention – EU proposal to restrict PFOA, its salts & PFOA-

related compounds• RMOA by BAuA for PFHxA

• Basel Convention Technical Guidelines• EU F-Gas and SEMI FAQ for compliance• Conflict Minerals • Substance evaluation methodology under RoHS • On hold: NMP & RCF
