Abstract:
A method of producing a semiconductor laser device includes the steps of preparing first and second substrate products each of which includes a substrate and a stacked semiconductor layer formed on the substrate, the first and second substrate products being different from each other; etching the first substrate product with a chlorine-based gas in a vacuum chamber by using a dry etching method; evacuating the vacuum chamber while monitoring a partial pressure of hydrogen chloride in the vacuum chamber so as to obtain the partial pressure of the hydrogen chloride within a predetermined range; after evacuating the vacuum chamber, introducing the second substrate product into the vacuum chamber while maintaining a vacuum state inside the vacuum chamber; and etching the second substrate product with a chlorine-based gas in the vacuum chamber by using the dry etching method.

Claim (Index 6):
The method of producing a semiconductor laser device according to  claim 1 ,\n wherein each of the first and fourth steps includes a step of forming a mask having at least one of hydrophobicity and water impermeability on the stacked semiconductor layer, in the first step, the first substrate product is etched through the mask formed on the stacked semiconductor layer of the first substrate product, and in the fourth step, the second substrate product is etched through the mask formed on the stacked semiconductor layer of the second substrate product.
