Semiconductor testing is a critical phase in the semiconductor manufacturing process. After the manufacturing process, semiconductor devices undergo various tests to ensure their functionality, quality, and reliability. Here's an overview of the practical steps involved in semiconductor testing: Wafer Testing: Before individual chips are cut from the wafer, the entire wafer undergoes testing. This process is known as wafer probing or wafer testing. Each chip's functionality is tested, and defective chips are identified. This step helps to maximize the yield of functional chips from a single wafer. Final Test (Post-Packaging Testing): Once the chips are cut from the wafer and packaged, they undergo a final test. This test is also known as post-packaging testing or final testing. The packaged chips are mounted on a test board, and electrical signals are applied to the chip to simulate real-world operating conditions. Various tests are performed to check the functionality of dif
