V-NAND Transition Drives Increased Demand for Process Control

Samsung – August 2013

Flash Memory Summit

■ Market Drivers

– Scalable bit density

– Lower power consumption

– Higher data rates

– Lower cost/bit

■ Process Implications

– ~20% increase in process

steps over planar favoring:

• Deposition

• Etch

• Process control

– Enabling architecture steps

are OCD-controlled:

• Many layer deposition/etch

• High aspect ratio structures

– Roadmap drives additional

process steps and tool

demand:

• 24 layer – Now

• 32 layer – 2015

• 48 – 100 layers – Future

All Leading-Edge Logic is Converting to FinFET

■ Market Drivers:

– Improved performance

demands from end users

– Highly competitive foundry

landscape for high volume wins

– Aggressive timing for

technology integration and

launch

■ Process Implications:

– FF process flow is more

complex and extensive than

planar

– 3D architecture poses complex

metrology challenges

– Increasing reliance on OCD for

critical layer process control

Notes:

Fiscal 2014

(a) Reflects the tax benefit for certain f irst quarter foreign losses related to entity classif ication elections that w ere approved by the IRS in the second quarter. The tax benefit of these f irst quarter losses w as recorded as a decrease to the second quarter

tax provision on a GAAP basis. The discrete tax adjustment for the second quarter also excludes the one-time benefit associate w ith the recognition of deferred tax assets related to the entity classif ication elections, resulting in a combined f irst and second

quarter Non-GAAP tax rate of approximately 36.5%.

(b) Represents charges associated w ith w riting dow n inventory related to a discontinued product line.

(c) Includes severance and RSU modif ication charges accrued in connection w ith the notif ication of future closure of our Nanometrics Germany Inc off ice (Nanda).
