Patent
Method for producing a surface-emitting laser
Toyoji Chino,Kenichi Matsuda +1 more
TL;DR: In this paper, a mask pattern is used to define a top mirror on a semiconductor substrate, and the mask pattern and the etching protective film are used as masks to protect the surface of the top mirror.
Patent
Method for fabricating semiconductor device
TL;DR: In this paper, a method for fabricating a semiconductor device having a first surface and a second surface substantially parallel to each other is presented, where the semiconductor chip is mounted on a submount such that the first surface faces the submount.
Patent
Optical module having a vertical-cavity surface-emitting laser
TL;DR: In this article, a first substrate, a first bump and a second bump are positioned with respect to the first substrate so that the second bump and the first bump come into contact with an upper surface of the electrode structure and the upper surfaces of the vertical-cavity surface-emitting laser.
Patent
Vertical-cavity surface-emitting semiconductor laser
TL;DR: In this paper, a vertical-cavity surface-emitting semiconductor laser with an upper face and a spacer layer covering over the entire upper face of the p-type bottom mirror is considered, where a sum d of optical path lengths of the spacer, the active region and the n-type top mirror in a perpendicular direction satisfies a relationship expressed by d=(1+n)•λ/2 (n: natural number) with respect to a wavelength λ of light oscillated from the active regions.
Patent
Method of making semiconductor device with air-bridge interconnection
TL;DR: In this paper, the air-bridge interconnection is obtained by side-etching controlled by using interconnection metal layer as an etching mask to remove a mass of semiconductor material under the metal layer.
