## 🚀 Quick Start

### 1. Install SDK

```bash
npm install @wia/semiconductor-testing
```

### 2. Initialize Test Session

```typescript
import { SemiconductorTesting } from '@wia/semiconductor-testing';

const testing = new SemiconductorTesting({
  facilityId: 'FAB-001',
  equipment: 'ATE-ADVANTEST-T2000',
  mode: 'production'
});

await testing.initialize();
```

### 3. Run Wafer Test

```typescript
const waferTest = await testing.createWaferTest({
  waferId: 'W-2025-001-0001',
  lotId: 'LOT-2025-001',
  deviceType: 'SOC-7NM',
  probeCard: 'PC-001',
  testProgram: 'TP-SOC-PARAM-V2.1'
});

const results = await waferTest.execute();
console.log(`Yield: ${results.yield}%`);
console.log(`Good dies: ${results.goodDieCount}`);
```

### 4. Analyze Results

```typescript
const analytics = await testing.analyzeYield({
  lotId: 'LOT-2025-001',
  waferIds: ['W-2025-001-0001', 'W-2025-001-0002'],
  metrics: ['yield', 'bin_distribution', 'defect_density']
});

console.log(analytics.summary);
```
