Environment Control
Temperature and Relative Humidity are controlled by computerized Building Automation System

Temperature and Humidity
  Item Control Limit Shut-down Limit
- Temperature 24 +/- 3 Deg C +/- 5 Deg C
- Relative Humidity 48 +/- 8 % +/- 12 %
Control Procedure
· BAS monitors clean room temperature and relative humidity on a real
  time basis.
· BAS print out daily monitoring reports every half an hour, and they are
  kept for 3 years as defined in record retention procedure(12SQP00160A).
· BAS delivers alarms in case a monitored value is out-of-control limits.
· Particle Count
Clean Room Class
Control Limit
Shutdown Limit
10 (0.3 micron)
> 10
10K (0.5 micron)
> 10K
100K (0.5 micron)
> 100K
Control Procedure
· QA monitors the clean rooms using portable particle counter on a monthly basis.
· If the measured value is out of control limit, “Inspection Report(I.R)” is issued to the
  manufacturing department for immediate corrective actions.
· If the measured number is out of shutdown limit, QA shutdown the line until
  verifying the Corrective action and Effectiveness by recheck.

All manufacturing areas are controlled for ESD as below.
· Environmental Control Frequency
  Item Control Limit MFG (All) QA (Sampling)
  · Humidity Control Relative Humidity 48 +/- 8 % MFG (All) QA (Sampling)
  · Temperature
Temperature 24 +/- 3℃ On-time(30min) Monthly
  · Floor
Surface to surface <1x109 Ohms - Monthly
Surface to Ground <1x109 Ohms - Monthly
  · Ionizer Control Decay Time(1000v → 100v) < 10 seconds Monthly Monthly
Balance (volt) < 35 volt Monthly Monthly
· Work stations
Item Control Limit MFG (All) QA (Sampling)
  · Facility Ground Power outlet to Earth < 1 Ohm (+1ohm) - Monthly
  · Equipment
Green wire to Ground < 1Ohm (+1ohm) Bi-annually Monthly
  · Work table Table mat top to Ground <109 Ohms Quarterly Monthly
Table Surface Resistivity <109 Ohms Quarterly Monthly
  · Chair Surface to Ground/surface <109 Ohms Quarterly Monthly
  · Cart / Rack Surface to Ground <109 Ohms Quarterly Monthly
· Verifications
· Perform ESD control Measurement Once/Month per “ESD audit check list” by QA.
· Process Control Audit Every Day for Disciplines
· If there is out of control, QA team issue CAR to take corrective action

New Product/Process Introduction

Document Management
Document Approval and Distribution
· Electronic Document Access through PC at Mfg
  Line & Office.

· Hard Copy Distribution for only TCM Document
  (PosiTrol Plan/Log, PM Check List, Set-Up Check
  List and OCAP). Visual Aid

· To distribute document with hard copy, Doc.
  Center put distribution” stamp in blue onthe first
  page, and each page is stamped “controlled
  copy”in red

· To remove all obsolete documents from the
  points of use, Doc. Center receives previous
  revision per distribution list when releasing new

Supplier Quality Control
1. New Supplier & Part Qualification program
  - On site Audit for Quality System & Process Control per SMES Procedure (Min 80% score)
  - Material Quality approval by internal CAB committee, and final approval by Customer.
  - Cross Functional Team activity.
2. Incoming Inspection
- Sampling Plan : Visual : LTPD 1.5% (S/S 153)
Dimension : LTPD 20% (S/S 11)
Destructive : LTPD 50% (S/S 5)
3. Supplier Audit Program
  - Perform Audit for Major Supplier Once per Year, or when severe quality issue arises.
4. Supplier Rating and Award
  - Rating : Quarterly (Criteria: Quality 30%, Cost 30%, Delivery 30%, Service 10%).
  - Best Supplier Award : ASE Group-wide on yearly basis.
5. MRB and Corrective Action

  - Material Review Board (MRB) make disposition for the Non-confirming material based on
    the DMR issued by Incoming QA.
  - The Supplier is required to provide 8D Corrective Action Report in 10 days.

Process Control Cycles
TCM provides all the basic control methodologies in the manufacturing line, and Manufacturing Line Personnel is fully authorized and empowered to shut down the process/equipment according to the Positrol Plans
Positrol (Positive Control) Cycles

Corrective Action Development

Statistical Process Control
The Statistical tools and Procedures are defined for effective monitoring of critical processes and equipment. Following are key elements of SPC control.
· Critical parameters are identified by engineering
ASEKR Criteria CPK ≥ 1.67
· Computerized SPC control and Reporting system.
- Alarm and E-mail notification to engineer for violation of Shewhart’s rule
- Provide alarm and trouble shooting information.
- Reporting for CPK, instability and upper/lower operating range with +/-3 sigma
· Monthly Engineering review and Action
- CPK and Instability
- Review control limits.
- Develop continuous improvement plan for CPK < 1.67
