The particle on the Projection Aligner may cause poor patterning and pellicle is considered to be the dustproof film for photomask protection.
If the pellicle on the photomask is damaged, Finex offers a service for damaged pellicle removal and replacement.
Customer may need multiple photomasks for the exposure test in order to verify the new manufacturing process. It usually costs a lot and takes a long time. To improve efficiency and reduce the cost, we developed a software to simulate the result after exposure so that we can provide customer the initial pattern design or verify the applicability of the existing pattern.
Finex uses this simulation system to obtain simulation results based on the exposure criteria and photoresist type provided by the customer and also the performance after exposure. In that case, we can put forward a new proposal or make suggestions for the original design.
By using this simulation system, we can accelerate verification, shorten development time, and effectively reduce cost.
Examples that Finex can handle are shown below:
OPC design proposal
Suggestions for HTM transmittance
CD / Residual film improvement design
