摘要： There is provided a method of manufacturing a ridge type LC-DFB semiconductor laser in which a laser substrate having a cladding layer made of a material for a ridge stripe formed on an active layer made of semiconductor. A stripe mask is formed on the cladding layer to form two lateral flat portions from the cladding layer, by a selective wet etching, so as to form a ridge stripe protruding therefrom and having a flat top portion at which the stripe mask capped. A grating mask is formed on the two lateral flat portions, side walls of the ridge stripe and the stripe mask. The grating mask has a periodic structure in the direction in which the ridge stripe extends. The two lateral flat portions and the side walls of the ridge stripe are dry-etched through the grating mask and then the two lateral flat portions and the side walls of the ridge stripe are wet-etched to form a grating of the material for the ridge stripe on the two lateral flat portions, the side walls of the ridge stripe and the active layer, so as to define a bracket grating portion adjacent to the ridge stripe.

摘要： When a potassium-containing substance is formed in to a film using an organic potassium complex as a potassium source by the CVD method, it is prevented that the film formation rate is changed with the lapse of time, and the potassium content in the film thus formed is changed.As a potassium source for vaporization used for depositing the potassium-containing substance on a substrate by the CVD method, a .beta.-diketone complex of potassium that has been melted by heating to a temperature higher than its melting point and then cooled to be solidified is used.
