Mobile Facilities Cart for Early Semiconductor Tool Commissioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delays in commissioning semiconductor processing tools occur due to the unavailability of site facilities like power, compressed air, and vacuum during construction or expansion of a semiconductor processing site, preventing the tools from being used for production.
Innovation Solution
A self-contained mobile facilities cart provides essential facilities such as electrical power, compressed air, and vacuum to semiconductor processing tools, allowing commissioning to take place independently of site connections through battery packs, compressors, and vacuum pumps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If semiconductor processing tools are delivered to a site before facilities are available, then tool delivery time is improved, but commissioning cannot proceed causing delays
Solution Approach 1:
The mobile facilities cart is prepared and configured with all necessary facilities (power, compressed air, vacuum) before the semiconductor processing tool is delivered to the site. This preliminary preparation allows the tool to be immediately connected and commissioned upon arrival, eliminating waiting time for facility installation while maintaining the ability to deliver tools early.
Solution Approach 2:
The mobile facilities cart serves as an intermediary between the semiconductor processing tool and the permanent site facilities. It provides temporary facilities that enable tool operation and commissioning before the permanent facilities are ready, acting as a bridge that resolves the timing mismatch between tool delivery and facility availability.
2Reliability
If permanent facility connections are required before tool commissioning, then facility reliability is improved, but commissioning timeline is extended
Solution Approach 1:
The mobile facilities cart is configured with reliable temporary connections that meet the operational requirements for tool commissioning. These preliminary connections include properly rated electrical outlets, compressed air regulators, and vacuum pump connections that provide sufficient reliability for testing and calibration activities before permanent facilities are operational.
Solution Approach 2:
The mobile facilities cart provides more than minimal facilities by including redundant power sources, multiple compressed air outlets, and comprehensive vacuum capabilities. This excessive provision of facilities ensures that all commissioning requirements can be met simultaneously without needing to wait for permanent facility completion, thereby compressing the commissioning timeline while maintaining adequate reliability.
