Abstract
A semiconductor device includes a lead frame having a down bond area, a die attach area and a dam formed between the down bond area and the die attach area. A bottom of the dam is attached on a surface of the lead frame. The dam prevents contamination of the down bond area from die attach material, which may occur during a die attach process.
