The present invention relates to a method of manufacturing the light emitting component of a VECSEL and the corresponding VECSEL. In the method a layer stack (2) is epitaxially grown on a semiconductor substrate (1). The layer stack comprises an active region (4), an upper distributed Bragg reflector (5) and a n- or p-doped current injection layer (13) arranged between the active region (4) and the semiconductor substrate (1). A mechanical support (6) or submount is bonded to an upper side of the layer stack (2) and the semiconductor substrate (1) is subsequently removed. A metallization layer (7) is optionally deposited on the lower side of the layer stack (2) and an optically transparent substrate (8) is bonded to this lower side. The proposed method allows the manufacturing of such a component in a standard manner and results in a VECSEL with a homogenous current injection and high efficiency of heat dissipation.

The invention discloses a method and the die for preparation of a hot forging ring billet of the guard ring of generator, and relates to a forging technique and the device of guard ring part of generator. The prior hot forging technique is flat-die forging, easily to produce crack in the process. The invention using confined shaping in die instead of flat-die forging, it improves the state of stress and prevents the crack effectively. With the symmetry of sphere plunger axis in the process of fan boring, the crystal particles are fine and uniform, which provides a perfect condition for cold strain intensification. With the jacket shaping of billet, it can improve lubrication and decrease friction, and can keep the temperature of the hot billet effectively, improving the plasticity and decreasing the shaping pressure. The invention solves the three problems that the crack is easy to produce, the structure property is not uniform, and the shaping pressure is large; compared with the prior technique, the invention has a projecting progress and a distinctive effect.

A method for heating a wafer to a predetermined temperature, the wafer being held by a holding unit and being accommodated in a processing container equipped with a heater. The wafer is heated to a processing temperature while positioning the wafer at an adjacent position that results form making the wafer approach the heating surface of the heater. After heating the wafer to the predetermined temperature, the wafer is separated from the flat bottom surface of the container body to a processing position. In this state, a processing chamber of the processing container is supplied with a processing fluid, while the holding unit and the heater are relatively moved close to and apart from each other intermittently or continuously. Accordingly, it is possible to quickly heat the substrate to a processing temperature while supplying the substrate with the processing fluid uniformly. This improves throughout and the homogenization in processing.
