SEMI New Activity Report Form (SNARF)



Activity Number: 5626
SNARF for: Revision to SEMI E154-0713, Mechanical Interface Specification for 450 mm Load Port AND to SEMI E166-0513, Specification for 450 mm Cluster Module Interface: Mechanical Interface and Transport Standard for addition of EFEM Pocket


Originating Global Technical Committee: Physical Interfaces & Carriers
Originating Technical Committee Region: North America
Task Force in which work is to be carried out: International 450 mm PIC TF & IPPI TF


1. Rationale:
Some process modules need higher or lower wafer transfer plane height that is outside the range of EFEM End effector’s range of vertical motion, which is constrained by the stroke and/or vertical position of the robot in the EFEM. As EFEM robot vertical motion must accommodates wafer transport from/to every slot in a FOUP on the Load port Option B
Proposed EFEM pocket volume will allow conventional robot to be able to have extra range of vertical motion by extending stroke or to be capable of servicing lower wafer transport height by lowerling the robot without changing Load port height requirement for Option B

Rate the Estimated Effect on the Industry
3: Major effect on a few companies - identify the relevant companies

Rate the Estimated Technical Difficulty of the Activity
I: No Difficulty - Proven concepts and techniques exist or quick agreement anticipated

2. Scope:
a: Define the areas to be covered or addressed by this activity or document:

1. New section 11 in the E154 for EFEM pocket.
