bin split

Bin split is the breakdown of dies by performance categories — sorting chips into speed, power, or quality bins based on test results, enabling product differentiation and revenue optimization.

What Is Bin Split?

• Definition: Distribution of dies across performance bins.
• Purpose: Product differentiation, pricing tiers, yield optimization.
• Bins: Speed bins, power bins, quality grades.

Why Bin Split?

• Performance Variation: Not all chips perform identically.
• Market Segmentation: Different customers need different performance.
• Revenue Optimization: Sell faster chips at premium prices.
• Yield Maximization: Sell slower chips at lower prices rather than scrap.

Bin Categories

Speed Bins: High-frequency (premium), mid-frequency (standard), low-frequency (value).
Power Bins: Low-power (mobile), standard power, high-performance.
Quality Bins: Grade A (perfect), Grade B (minor defects), Grade C (functional but limited).

Bin Split Analysis

• Measure performance distribution across wafer.
• Define bin boundaries based on market requirements.
• Calculate percentage in each bin.
• Optimize pricing and positioning.

Applications: Product portfolio management, pricing strategy, yield optimization, market segmentation.

Typical Distribution: Normal distribution centered on typical corner, tails determine premium and value products.

Bin split is revenue optimization tool — turning manufacturing variation into product portfolio and maximizing revenue from every wafer.
