Solution Overview

Problem

Existing semiconductor device packages face challenges in achieving compact size, reduced thickness, and improved operational stability due to thermal interference and compatibility issues between components like controllers and oscillators, which affect storage performance and compatibility with host systems.

Innovation Solution

A semiconductor device package design that integrates a substrate with a connector, nonvolatile memory, memory controller, and oscillator, where the oscillator is electrically connected to the memory controller and sealed with a resin to reduce thermal interference and enhance compatibility, using a System-in-Package (SiP) configuration with optimized component placement and bonding wires for efficient heat dissipation and signal integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If components are integrated in the same package, then device compactness is improved, but thermal interference between components increases

Engineering Contradiction:
Improvedevice compactnessVSAvoidthermal interference
Core Design Contradiction:
Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent divides the internal package structure into distinct regions: a first region housing the controller and a second region housing the oscillator. This spatial segmentation isolates thermally sensitive components from heat-generating components, reducing thermal interference while maintaining package compactness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a heat dissipation structure (heat sink) as an intermediary element between the controller and oscillator. This mediator captures and dissipates heat away from sensitive components, enabling close integration without excessive thermal interference.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Length of stationary object

If components are placed closer together, then device thickness is reduced, but operational stability decreases due to thermal effects

Engineering Contradiction:
Improvedevice thicknessVSAvoidoperational stability
Core Design Contradiction:
Length of stationary objectVSReliability

Solution Approach 1:

The package is segmented into vertically stacked regions with the controller in a first region and the oscillator in a second region. This vertical segmentation allows reduced device thickness while maintaining adequate thermal separation through the layered structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A heat dissipation structure is positioned between the controller and oscillator to act as a thermal buffer. This intermediary enables closer component placement for reduced thickness while protecting the oscillator from thermal effects that would compromise operational stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Volume of moving object

If oscillator is sealed with resin, then device compactness is improved, but heat dissipation from oscillator may be affected

Engineering Contradiction:
Improvedevice compactnessVSAvoidheat dissipation
Core Design Contradiction:
Volume of moving objectVSLoss of energy

Solution Approach 1:

The package structure segments the oscillator into a sealed region (for compactness and protection) and a heat dissipation region. The heat dissipation structure extends from the sealed oscillator region to an external surface, allowing compact sealing while maintaining thermal pathways for effective heat dissipation.

Inventive Principle:
Principle #1Segmentation
