Latest Patents

One of Tom's latest patents is an etching method and etching apparatus. This innovation involves a process where silicon (Si) from the surfaces of semiconductor wafers dissolves into an etching liquid stored in a process bath. A concentration sensor detects the silicon concentration, allowing for the controlled discharge of the etching liquid when it reaches a designated level. Subsequently, a new etching liquid, equal to the amount discharged, is supplied to the process bath. This method effectively restricts the etching rate from rising excessively immediately after the exchange of etching liquid.
