Solution Overview

Problem

Existing semiconductor processing apparatuses are inadequate in maintaining a clean vacuum environment, leading to contamination and reduced semiconductor wafer yield due to inefficient particle removal during the vacuum creation process.

Innovation Solution

The processing apparatus incorporates an intersecting module with multiple support members and internal ventilating plates arranged in a staggered and inclined manner to filter out contaminants from the gas flow, ensuring a clean vacuum is maintained and preventing particle contamination of the pump and wafer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing processing apparatus are used to create vacuum, then vacuum is created, but particles are not effectively removed leading to contamination

Engineering Contradiction:
Improvevacuum qualityVSAvoidparticle contamination
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intersecting module with ventilating plates as an intermediary component between the processing chamber and pump. This module actively removes particles from the gas flow through its structured design, preventing particle contamination while maintaining vacuum quality. The ventilating plates act as a mediator that separates the harmful particle removal function from the vacuum creation process.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the particle removal function from the traditional vacuum creation process. By incorporating a dedicated intersecting module with ventilating plates, the system separates particle removal from simple vacuum pumping, allowing each component to specialize in its primary function while working together to achieve both clean vacuum and particle elimination.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If traditional pump systems are used, then gas is exhausted, but particles contaminate the pump and reduce uptime

Engineering Contradiction:
Improveapparatus uptimeVSAvoidparticle accumulation in pump
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The intersecting module performs preliminary particle removal before gas enters the pump system. By proactively eliminating particles from the gas flow upstream, the system prevents particle accumulation in the pump, thereby extending pump life and maintaining apparatus uptime without requiring frequent maintenance or pump replacement.

Inventive Principle:
Principle #9Preliminary anti-action

3Productivity

If scaling-down process is implemented, then production efficiency increases, but manufacturing complexity increases

Engineering Contradiction:
Improveproduction efficiencyVSAvoidprocessing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the vacuum processing system into distinct functional modules: the processing chamber, the intersecting module with ventilating plates, and the pump system. This segmentation allows each component to be optimized independently for its specific function while maintaining overall system efficiency. The modular design simplifies manufacturing and maintenance despite the advanced functionality required for scaled-down production.

Inventive Principle:
Principle #1Segmentation
