The Opportunity• Very tight temperature and humidity requirements . . .

– 70F+/-2 (21C+/-1) and 45% RH +/- 3%

• Combined with a large amount of exhaust and subsequent make up airmake up air . . .

– 650,000 cfm (307 m3/sec) = 2 Macy’s Kermit balloons per second

• Combined with the need to recirculate a large volume of air through the filters for cleanlinessthrough the filters for cleanliness . . .

– 4,400,000 cfm (2077 m3/sec) = 22 Goodyear blimps a minute

• Combined with hundreds of process tools with vacuum pumps, RF generators, and support equipment . . .p p , g , pp q p

• Combined with extensive use of deionized (DI) water to rinse the wafers during processing . . .

Could lead to annual power consumption of 170,000 mWh (10,000+ homes worth)and water consumption of 3 million gallons/day (6,000 homes worth)

Annual utility bills could total $20M $25M99

Annual utility bills could total $20M - $25M

Production vs. Operation

• To make a single chip requires an average of:– 0.2 kWh of electricity (75% front end / 25% back end) = .131kg of CO2e

0 2 gallons of water– 0.2 gallons of water– Variability is about 4X

• A fairly large fab can produce about 1 billion chips per year– 200 million kWh/yr = 131,000 metric tons CO2e/yr

• Alternate = (24) 3MW wind turbines in west Texas– 200 million gallons/yr

• In just 5 years of operation a chip will use: – 0.006 kWh for a small battery powered device (2 AA batteries of energy)– 1,575 kWh for a 24 hour/day high powered internet server– Variability is 250,000X

• In 5 years of operation those billion chips could use:– Between 3,000 kWh to 1.6 billion kWh

However, many chips are used in energy saving applications that save billi f kWh

Sustainability

101

What is Sustainability?

• Simply: The Balance of People, Profit, and the Planet

• Officially: "to meet the needs of the present without compromising theOfficially: to meet the needs of the present without compromising the ability of future generations to meet their own needs.” - Brundtland Commission, 1989

• At TI: Reducing waste and inefficiency – ZERO wasted resources

102

Our TI History

• Leadership in Business Ethics– Fair work practices; honesty & integrity

TI Founders literally wrote a book on ethics (TI Ethics Booklet 1961)– TI Founders literally wrote a book on ethics (TI Ethics Booklet, 1961)

• Strong Community Engagement / Corporate Citizenship– United Way– Education support & involvement– Arts & cultural support– Diversity leadership

• Economic Prosperity– One of the technology pioneers and leaders in Dallas– Profit sharing for employees

• Environment– History of regulatory compliance– Energy management since 1973

103

Energy management since 1973

Environmental PolicyTexas Instruments Incorporated responsibly creates, makes and markets technology for innovators around the world. TI consistently complies with applicable regulations and customer requirements. TI commits to continual improvement of its operations, progressively reducing the potential impact of its activities, by focusing on employee health and safety, productivity and pollution prevention. This commitment is tracked through the setting and reviewing of relevant objectives and targets for TI operations

Supplier - Vacuum Pumps

• Vacuum Pumps: (reduced cooling load by >300 tons)– Large fab will have over 600 pumps

Met with suppliers and asked about product efficiency roadmap– Met with suppliers and asked about product efficiency roadmap– We were one step removed from direct purchase (vacuum pumps come

with the manufacturing tool), so feedback to pump manufacturer was “low price” not “low operating cost”

– Pump manufacturers had efficiency to offer and delivered >35% improvement in just a couple of years

– Annual operating savings of about $4k/yr per pumpWorked with industry consortium (ISMI) and vendors to develop an idle– Worked with industry consortium (ISMI) and vendors to develop an idle signal protocol (SEMI E54 standard)

109

Supplier – Point of Use Chiller

• Process Cooling (PC) Water / POU Chiller – A couple hundred point of use chillers are used in a large fab for specific

li / h ti t kcooling / heating tasks– Most units are compressor based– Thermoelectric chillers are smaller, less expensive, run tighter control

temperatures use less cooling water and operate for about 1/10th the costtemperatures, use less cooling water, and operate for about 1/10th the cost (0.5kW vs 5kW)

– Reduced delta P and increased delta T in heat exchangers

Supplier - Exhaust

• Exhaust: (reduced exhaust load by >100,000 cfm)– All exhausted air must be meticulously reconditioned– Returned some general exhaust (heat) to space– Identified top tool internal constraints and worked pressure drop issues– Still have many opportunities

Supplier – POU Abatement

• POU Abatement– Wet burn scrubbers for point of use abatement – Worked with supplier on more efficient burner (natural gas)– Worked with supplier on more efficient water chamber– Combo has reduced natural gas and water use by 50% each

112

Facilities Equipment Energy

• Chiller Plant– Negawatts to reduce the need – right size the plant to the load

High efficiency chillers optimized system (variable speed pumps/towers)– High efficiency chillers – optimized system (variable speed pumps/towers)– Split chiller plant – high temp (50-54F) / low temp (40-42F)– Heat recovery (also saves water)

• Recirculating Air– Reduce the quantity of air– Specify high cfm/Watt units (variable speed, good motor/fan design)

S t ff t l d– System effect – low pressure drop

• Compressed Air– Check system for leaks and losses– Match compressor type to load– Heat recovery

Utility Savings & Best Practices

• Utility saving projects– Began dedicating capital to utility savings projects in late 2005– Initial payback threshold was 3 years – later reduced to 1.5 years– Buildings also implement local expense projects each year

• Best Practices ChecklistBest Practices Checklist– Checklist of of 49 good practices that buildings can use to assess their

performance– Benchmarked every site in 2008, average improvement of 4.5% in 2009y , g p– Refining and growing the list to become more of a Best Practice Standard– lncorporating LEED-EB credits into this list
