Varian H4152001 Uniformity Monitor

Varian H4152001 Uniformity Monitor 

 Introduction

The Varian H4152001 uniformity monitor is a specialized detection unit for ion implantation machines, used to collect real-time data on the distribution of ion implantation dose on the wafer surface.

1. Multi point synchronous sampling, obtaining uniformity data of the entire wafer injection at once, quickly identifying regional deviations;

2. Equipped with a built-in signal calibration circuit, it is not easy to drift during long-term operation, ensuring consistency in testing between batches;

3. Adapt to the vacuum chamber environment of the machine and withstand the radiation and thermal effects under ion implantation conditions;

4. The uniformity report can be directly uploaded to the host, and exceeding the standard will automatically trigger a process alarm;

5. Modular board structure, can be replaced separately after a fault, without the need to shut down the entire machine for disassembly.

1. Compatible models: Varian 350D/350DE/300XP ion implantation machine;

2. Test object: Uniformity of ion implantation dose on wafers;

3. Data output: digital signal docking with the main control system of the machine;

4. Working environment: inside the vacuum chamber;

5. Board version Rev. C.

1. Online monitoring of doping uniformity in ion implantation process wafers;

2. Verify the beam distribution of the scanning ion beam;

3. Continuous monitoring of process stability during mass production;

4. Verification of injection effect after regular maintenance of the machine;

5. Data collection for troubleshooting ion implantation chambers.

This H4152001 is the core testing spare part of Varian ion implantation machine, which directly determines the yield control capability of doping process.
