SEMI New Activity Report Form (SNARF)



Activity Number: 5485
SNARF for: New Standard: Guide for Incoming/Outgoing Quality Control and Testing Flow for 3DS-IC Products


Originating Global Technical Committee: 3DS-IC
Originating Technical Committee Region: Taiwan
Task Force in which work is to be carried out: 3DS IC Testing Task Force


1. Rationale: To ensure consistent yield control of 3DS-IC products, common criteria for incoming quality control (IQC) and outgoing quality control (OQC) of OSATs (outsourced sub-assembly and test providers) are needed. The generic testing flows for different 3DS-IC products to also be defined in this document will expedite the progress of 3DS-IC testing.

Rate the Estimated Effect on the Industry
2: Major effect on an industry sector - identify the relevant sector

Rate the Estimated Technical Difficulty of the Activity
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

2. Scope:
a: Define the areas to be covered or addressed by this activity or document:
This guide will define the criteria of incoming quality control (IQC) and outgoing quality control (OQC) of OSATs, such as appearance, TSV void percentage by X-ray inspection, etc., to clarify the manufacturer’s responsibilities and to improve product yield. This guide will also define the generic testing flows for different 3DS-IC products, such as chip on chip (CoC), chip on substrate (CoS), stacked chip on substrate (CoS), wafer on wafer (WoW), etc., to help accelerate the progress of 3DS-IC testing.

b: Expected result of activity
New Standard
