- Fewer respins and faster time-to-market

## 2. Chiplet-Based Design

**What Are Chiplets?**
Instead of one monolithic die, multiple smaller chiplets are integrated using advanced packaging.

**Benefits:**
- **Better yields:** Smaller dies = higher manufacturing yield
- **Mix-and-match:** Combine different process nodes
- **Modularity:** Reuse proven IP blocks
- **Cost reduction:** Only use advanced nodes where needed

**Standards:**
- **UCIe (Universal Chiplet Interconnect Express):** Industry standard for chiplet communication
- **HBM (High Bandwidth Memory):** 3D stacked memory
- **2.5D/3D packaging:** Silicon interposers and through-silicon vias (TSV)

**Real-World Examples:**
- AMD EPYC processors (multiple chiplets)
- Intel Meteor Lake (Foveros 3D packaging)
- Apple M-series (multiple dies in one package)

## 3. Advanced Packaging Technologies

**Beyond Traditional Packaging:**

**2.5D Integration:**
- Multiple dies on silicon interposer
- High-speed, high-bandwidth interconnects
- Used in: GPUs, HPC processors

**3D Stacking:**
- Vertical stacking of dies
- Through-Silicon Vias (TSV) for connections
- Used in: HBM memory, image sensors

**Fan-Out Wafer Level Packaging (FOWLP):**
- Redistribution layers for flexible I/O
- Better thermal performance
- Used in: Mobile processors
