Granted: 2007-07-11
Abstract: In a semiconductor light emitting device such as a semiconductor laser using nitride III-V compound semiconductors and having a structure interposing an active layer between an n-side cladding layer and a p-side cladding layer, the p-side cladding layer is made of an undoped or n-type first layer 9 and a p-type second layer 12 that are deposited sequentially from nearer to remoter from the active layer. The first layer 9 is not thinner than 50 nm. The p-type second layer 12 includes a p-type third layer having a larger band gap inserted therein as an electron blocking layer. Thus the semiconductor light emitting device is reduced in operation voltage while keeping a thickness of the p-side cladding layer necessary for ensuring favorable optical properties.

Granted: 2005-04-01
Abstract: This invention describes a method to produce an especially mixture-colored luminous diode light-source, in which at least one part of the primary radiation sent from a chip is converted by means of luminescence conversion. It is related to a chip with an electrical contact on the front side (i.e., the side, which faces towards the radiation direction), on its surface a luminescence-conversion material is coated in the form of a thin layer. The electrical contact on the front side is heightened before the coating through applying a conductive material on the electrical contact-face. The method allows a suitable adjustment of a definite color-position through the control of the color-position (IEC color-chart) and the thinning of the layer composed of luminescence-conversion material. In addition, the method is especially suitable to simultaneously produce several luminous diodes light-sources from several chips of the same kind in a wafer-compound.

Title: Field effect transistor with stressed channel and method for making same
Inventor: DORIS BRUCE B
IPC: H01L21/84
Filed: 2003-11-27
Granted: 2005-12-21
Abstract: Field effect transistor with increased charge carrier mobility due to stress in the current channel 22. The stress is in the direction of current flow (longitudinal). In PFET devices, the stress is compressive; in NFET devices, the stress is tensile. The stress is created by a compressive film 34 in an area 32 under the channel. The compressive film pushes up on the channel 22, causing it to bend. In PFET devices, the compressive film is disposed under ends 31 of the channel (e.g. under the source and drain), thereby causing compression in an upper portion 22A of the channel. In NFET devices, the compressive film is disposed under a middle portion 40 of the channel (e.g. under the gate), thereby causing tension in the, upper portion of the channel. Therefore, both NFET and PFET devices can be enhanced. A method for making the devices is included.
