Quality Improvement
Principle of lifetime test:
Sinton (bct400): Measure with the infrared excitation source and transient 850nm; injection level: 5e14cm-3 (N-type) and 1e15cm-3 (P-type); detection depth: 3mm.
Semilab (e-pcd): 950nm laser excitation source; injection depth: 100μs.
Lower improvement against target resistivity of P-type cell technology
Improvement Against Hidden Crack and Edge Collapse of Mono-crystalline Wafer
Client and Partner Verification
Benchmarking communication about charging WIS hidden crack & edge collapse detection
Coordinate with clients and implement special improvement of client-end process hidden crack
