摘要： A method of performing anisotropic etching more than once with respect to a semiconductor substrate (1) is provided with the steps of performing first-time anisotropic etching by using a first etching mask (2) so as to form a first anisotropically etched region (4) which is hollow, forming a second etching mask (7) over the first etching mask (2), performing second-time anisotropic etching by using the second etching mask (7), and previously forming the first etching mask (2) from a material which is resistant to an etchant used for patterning the second etching mask (7) before the first-time anisotropic etching is performed. Thus, the edge portion (6) of the first etched region (4) is protected so that its configuration is excellently maintained. By way of example, either of the etching masks is composed of a dielectric material such as a silicon dioxide film, while the other etching mask is composed of a metallic material such as Au and Ti, and the second-time anisotropic etching is performed by using diluted potassium hydroxide.

摘要： An optical head for optical recording and reproducing apparatuses is disclosed. The optical head comprises a semiconductor laser, a mirror for reflecting a light beam emitted from the semiconductor laser, a diffraction grating for dividing the light beam into zero order, plus and minus first-order beams. It also comprises a holographic diffraction grating being arranged at an optical path of the beams divided by the diffraction grating, an objective lens for focusing the beams on a disk and causing the beams reflected from the disk to be incident on the holographic diffraction grating to diffract the beams, and a photodetector for detecting a tracking error signal by receiving the beams diffracted by the holographic diffraction grating. The semiconductor laser has a beam incident area onto which the beam reflected from the disk is incident. The beam incident area acts to scatter or absorb the incident beam. As a result, the optical head is able to obtain a stable tracking error signal.
