Synchronized 3D Display for Multi-Die Micro-Bump Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integrated circuit design faces challenges in aligning and editing micro-bumps across adjacent dies, as the alignment and effects of micro-bump placement in one die are not apparent in another, especially when each die is edited individually using different layout editors or technologies.
Innovation Solution
A system and method for synchronizing the display and edit of multiple connected documents within a single document editing application, allowing real-time viewing of changes across multiple windows, with active and background document elements, facilitating micro-bump alignment and editing across stacked documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If each die is displayed and edited individually using separate layout editors, then each die can be edited independently, but the alignment and effect of micro-bump placement between adjacent dies cannot be observed or corrected effectively
Solution Approach 1:
The patent merges multiple separate layout editors into a single integrated editor that can display and edit multiple dies simultaneously. The system combines the editing capabilities for first die and second die into one unified interface, allowing designers to view both dies and their micro-bump alignments in the same window, thereby preventing loss of alignment information while maintaining independent editing functionality.
Solution Approach 2:
The patent introduces a new dimension of viewing by displaying multiple dies in a three-dimensional stacked arrangement within a single editor window. Instead of separate two-dimensional views in different editors, the system renders dies in vertical stacks showing their spatial relationships and micro-bump alignments across layers, enabling observation of alignment effects that were previously invisible.
2Manufacturing precision
If a designer accesses and edits each die layout one by one, then detailed editing is possible, but the process is time-consuming and alignment corrections are difficult
Solution Approach 1:
The patent implements real-time feedback mechanisms where the system automatically detects and highlights misaligned micro-bumps across adjacent dies. When a designer edits micro-bump placement in one die, the system immediately updates the display to show the alignment status with adjacent dies, providing visual feedback about alignment quality. This eliminates the need for manual comparison and repeated accessing of multiple editors, significantly reducing editing time while maintaining precision.
Solution Approach 2:
The system performs preliminary alignment analysis and displays predicted alignment results before the designer finalizes edits. The editor pre-calculates and shows how micro-bump placements will align across dies, allowing designers to make informed adjustments in advance. This preliminary action prevents costly iterative revisions and reduces overall editing time.
3Adaptability or versatility
If different layout editors or technologies are used for different dies, then flexibility in editing is maintained, but synchronization and alignment verification become complex
Solution Approach 1:
The patent creates a universal editor platform that can handle multiple die formats and technologies within a single interface. The system is designed to import and display layouts from different editor technologies and formats, providing a common viewing and editing environment. This universal platform synchronizes the display of multiple dies regardless of their original editor or technology, eliminating the complexity of managing multiple separate editor instances while maintaining adaptability to different die types.

AI summary
A system and method for synchronizing the display and edit of a plurality of connected layouts or documents within a single display. A first document or plurality of elements may be displayed as active and a second document or plurality of elements may be displayed as non-active background in a first window. The second document or plurality of elements may be displayed as active and the first document or plurality of elements may be displayed as non-active background in a second window. Any action detected in either window may be displayed in the other window. Upon selection of any active element or predefined net list, the elements physically or logically connected to the selected element or net list may be highlighted in the active documents, listed, or otherwise identified. An inter-document net list may identify connections between existing net lists in multiple documents.
