Solution Overview

Problem

Current semiconductor device manufacturing processes are costly due to inefficiencies in processing tools that lack integration of single and twinned processing chambers, leading to redundant resource usage and increased operational expenses.

Innovation Solution

A semiconductor device manufacturing platform with a transfer chamber that allows for the efficient transport of substrates between single and twinned processing chambers, utilizing substrate handlers and hand-off locations for resource sharing and simultaneous processing, thereby reducing operational costs by enabling shared chemical and gas delivery systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate processing chambers are used for each processing step, then processing flexibility is maintained, but manufacturing cost increases due to redundant resources

Engineering Contradiction:
Improveprocessing flexibilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent combines multiple processing chambers (first processing chamber and second processing chamber) into a single integrated system with a shared transfer chamber. This merging allows multiple processing functions to be performed while sharing common infrastructure resources such as the transfer chamber, substrate handlers, and chemical/gas delivery systems, thereby reducing manufacturing costs while maintaining processing flexibility through the ability to perform different processing steps in different chambers.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transfer chamber is designed as a universal component that serves multiple processing chambers simultaneously. It provides a common interface and substrate transport mechanism for both the first and second processing chambers, as well as the load lock chamber. This multi-functional design eliminates the need for separate transfer mechanisms for each chamber, reducing overall system cost while maintaining the ability to flexibly process substrates through different chamber combinations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple substrate handlers are used to service multiple processing chambers, then substrate transport efficiency improves, but device complexity increases

Engineering Contradiction:
Improvesubstrate transport efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The first and second substrate handlers are designed as multi-functional devices that can service multiple processing chambers. The first substrate handler can load substrates into both the first processing chamber and the second processing chamber, while the second substrate handler can also service both chambers. This universal design allows efficient substrate transport throughout the system without requiring a separate dedicated handler for each chamber, thereby improving productivity while controlling device complexity through resource sharing.

Inventive Principle:
Principle #6Universality (Multi-functionality)
