Solution Overview

Problem

Current reactor systems require exclusive access to resources like vacuum pumps and reactant sources for efficient thin film deposition, leading to inefficiencies and potential cross-contamination between chambers, especially when depositing multiple materials concurrently.

Innovation Solution

Implementing a method where a computing device determines and manages exclusive access to resources such as vacuum pumps and reactant sources for each reaction chamber based on their specific needs, ensuring that chambers only access shared resources when necessary to prevent contamination and optimize deposition processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If multiple reactor chambers share common resources (vacuum pump, reactant source), then device complexity and physical space requirements are reduced, but cross-contamination between chambers increases and resource access conflicts occur

Engineering Contradiction:
Improvereactor system complexityVSAvoidcross-contamination
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The system segments resource access by implementing separate access paths and isolation mechanisms for each reaction chamber. Valves and flow control elements divide the shared resource system into chamber-specific access routes, allowing physical sharing while maintaining logical separation to prevent cross-contamination.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces intermediary components such as valves, flow controllers, and isolation elements between reaction chambers and shared resources. These intermediaries act as mediators that regulate material flow and prevent direct cross-contamination while enabling resource sharing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If reactor chambers operate concurrently using shared resources, then productivity and deposition efficiency increase, but resource access conflicts and process interference occur

Engineering Contradiction:
Improvedeposition throughputVSAvoidprocess stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system dynamically adjusts resource allocation and access rights based on real-time process requirements. The control system monitors chamber states and automatically adjusts valve positions, flow rates, and access permissions to enable concurrent operations when safe and prevent interference when necessary.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms that monitor pressure, flow rates, and chamber states in real-time. This feedback enables the control system to detect potential conflicts or contamination risks and automatically adjust resource access to maintain process stability while maximizing throughput.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If exclusive access to resources is granted to prevent cross-contamination, then manufacturing precision and material purity are improved, but productivity and resource utilization decrease

Engineering Contradiction:
Improvefilm deposition qualityVSAvoidreactor throughput
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system makes resources universal by enabling them to serve multiple reaction chambers simultaneously through controlled sharing. The same vacuum pump, reactant source, and control system can serve multiple chambers concurrently or sequentially, maintaining deposition quality while maximizing resource utilization and throughput.

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

Solution Approach 2:

The system performs preliminary actions by pre-configuring access rights, purging pathways, and isolation mechanisms before concurrent operations begin. This preparation ensures that when multiple chambers access shared resources, contamination is prevented and process quality is maintained from the outset.

Inventive Principle:
Principle #10Preliminary action

4Productivity

If multiple dedicated reactor systems are used to deposit different thin film materials concurrently, then productivity and deposition efficiency increase, but device complexity, cost, and physical space requirements increase

Engineering Contradiction:
Improvemulti-material deposition capabilityVSAvoidnumber of reactor systems
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system merges multiple dedicated reactor functions into a single integrated platform. Multiple reaction chambers share common resources including vacuum pump, reactant source, control system, and diagnostic equipment, achieving multi-material deposition capability while reducing the total number of independent reactor systems needed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system creates universal resources that can serve multiple chambers and multiple material deposition processes. The shared vacuum pump, reactant source, and control system can be dynamically allocated to different chambers based on process requirements, enabling one reactor system to perform the function of multiple dedicated systems.

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

AI summary

A reactor system includes a first reaction chamber, a second reaction chamber, a resource, one or more processors, and a computer readable medium storing instructions that, when executed by the one or more processors, cause the one or more processors to perform functions. The functions include making a first determination that providing a first reaction chamber access to a resource of a reactor system requires that the first reaction chamber have exclusive access to the resource. The resource includes a reactant source and/or a vacuum pump. The functions also include making a second determination that a second reaction chamber does not require access to the resource. The functions also includes providing the first reaction chamber exclusive access to the resource in response to making the second determination.
