Goals & Objectives
■  For top 3 toolsets
ì  Improve Availability to >90%.
ì  Decrease CV of AV to <10% for all chambers/mainframes
ì  Top priority AMAT Endura PVD toolset – 6 Tools
■  Opportunities in Availability by:
ì  Challenging unscheduled downtime.
ì  Reducing variation in scheduled downtime.
MPM™ Scorecard
■  Performed multi site
high level review
■  Major functions and
practices benchmarked
ì  People
ì  Systems
ì  Performance
■  Identify and prioritize
initial processes to focus
on
■  Busy improving them
Data Integrity

■ 
■ 
Data integrity / quality issues hindered analysis.
All information in free text form.
Incorrect logging of Scheduled/Unscheduled work.
Initial improvement through application of SEMI E10 & E58
states.
■  Fault Codes were introduced enabling categorization.
■  Training carried out to support.

■  >50% of chambers are below 1:1.
■  High Unscheduled downtime leads to high variability.
MPM™ KPI Setup
■  KPI’s are required to establish a baseline & track
performance.
■  The following KPI’s were installed.
ì  Output.
ì  Availability.
ì  CV of AV.
ì  Scheduled & Unscheduled downtime.
ì  M-Ratio.
ì  Fails within 48 Hours.
ì  Green-Green time for scheduled work.
ì  First Time Qual.
ì  Response Time.
Examples of MPM™ KPIs
CV of AV
M Ratio
Fail within 48 Hours
MPM ™ KPI Reporting
Automation
■  Data automatically extracted from database, summary table
generated, analysis carried out and charts produced.
MPM™ Endura Tiger Team
■  Tiger teams were formed in each of the areas of focus.
ì  These were cross functional teams including:
●  Equipment Engineering.
●  Process Engineering.
●  Operations.
●  Industrial Engineering.
As Required
■  The task of the Tiger Team is to Review the data, identify
opportunities, prioritise, create action plans and execute.
■  Initial focus was on reduction of Unscheduled Downtime.
Unscheduled D/T Pareto
■  Pareto Analysis indicated that for the Endura toolset the
main contributors were Handling/Breakage & Pressure
related issues. (480 & 330 Hours resp)
M-Ratio: Scheduled /
Unscheduled Downtime
■  Handling faults - source of the issues was defective chucks
in the Endura SIP chambers. Chuck types replaced.
■  Handling/Breakage failures have reduced to a total of 3.4
hrs/quarter vs. 240
■  Chamber pressure related failure reduced to 1 hr/quarter vs.
168 hrs/quarter
M-Ratio Increased
■  Focussed on unscheduled downtime taking action to:
ì  Determine the root cause and eliminate
ì  Updating PM content to mitigate this fail mode.
■  As a result the Endura
M-Ratio has Increased
significantly over the last
6 Months.
MTTR/MTBF Variability
■  Data Analysis highlighted significant
variation in the duration of scheduled
tasks
■  Delivered improvement in 2 phases:
ì  Phase 1: Reduce the variation in
completion of the scheduled work.
ì  Phase 2: Reduce the mean time to to
complete the scheduled work.
■  RCA carried out to identify phase 1
improvement opportunities.
MTTR/MTBF Variability
■  As a result variance and average duration for scheduled
tasks are reducing, Specs Updated.

Results To Date - PVD
The results of the joint MPM™ Tiger Team work:
Increasing the PVD perfromance enabled a significant
reduction in a BEOL WIP bubble -> higher TPT, faster CT
Low CV => uniform output, higher predictability, lower
maintenance costs
Fab Wide
On track to deliver a quarterly Gross Margin growth of
$25M
