The etching of silicon releases energy. This means that the faster the etch is, the more heat needs to be dissipated. Similarly, the larger a percentage of the wafer is etched, the more heat must be dissipated. Process A is the fastest etch and as seen above, the exposed area also plays an important role. The
The etching of silicon releases energy. This means that the faster the etch is, the more heat needs to be dissipated. The consequence is the same if a larger percentage of the wafer is etched. Process A is the fastest etch and as seen above, the exposed area also plays an important role. Above 10 % exposed area the oxide mask erodes quickly.
