Solution Overview

Problem

The miniaturization and increased functionality of semiconductor device packages require integrating multiple electronic devices through 3D stacking, but supporters occupy valuable substrate area, limiting space for electronic components and posing stability challenges.

Innovation Solution

A semiconductor device package design featuring a first and second carrier with asymmetrically arranged supporters fully sealed in an encapsulant, reducing the number of supporters and maintaining structural stability without occupying additional space, allowing for more electronic components and avoiding oxidation issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If multiple supporters are used to connect carriers in 3D stacking, then structural stability is improved, but available substrate area for electronic components is reduced

Engineering Contradiction:
Improvestructural stabilityVSAvoidsubstrate area
Core Design Contradiction:
Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The patent applies asymmetry by arranging supporters non-uniformly on the substrate. Instead of symmetric distribution, supporters are positioned at specific asymmetric locations optimized for structural support while maximizing available area. This asymmetric arrangement allows the package to maintain stability with fewer supporters, thereby increasing the substrate area available for electronic components.

Inventive Principle:
Principle #4Asymmetry

2Stability of the object's composition

If supporters are placed close to substrate edges, then structural support is improved, but oxidation resistance is worsened due to exposure

Engineering Contradiction:
Improvestructural supportVSAvoidoxidation resistance
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent extracts or removes supporters from direct exposure to the external environment by fully encapsulating them within the encapsulant material. This isolation technique protects the supporters from oxidation and other environmental harmful factors while maintaining their structural support function. The encapsulant creates a protective barrier between the supporters and external oxidizing conditions.

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-affected harmful factors

If supporters are fully encapsulated, then oxidation resistance is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveoxidation resistanceVSAvoidmanufacturing complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the encapsulation process with the existing packaging manufacturing workflow. Rather than adding a separate encapsulation step, the process integrates supporter encapsulation into the standard packaging sequence, utilizing the same encapsulant material and processing conditions already employed for device encapsulation. This integration minimizes additional manufacturing complexity while achieving complete supporter protection.

Inventive Principle:
Principle #5Merging (Combining)
