20080199982 | Fabrication Process for Package With Light Emitting Device On A Sub-Mount - A method of fabricating a package with a light emitting device includes depositing a first metallization to form a conductive pad on which the light emitting device is to be mounted and to form one or more feed-through interconnections extending through a semiconductor material that supports the conductive pad. Subsequently, a second metallization is deposited to form a reflective surface for reflecting light, emitted by the light emitting device, through a lid of the package. Deposition of the second metallization is de-coupled from deposition of the first metallization. | 08-21-2008 |
20090101897 | PACKAGE FOR A LIGHT EMITTING ELEMENT - A high-brightness LED module includes a substrate with a recess in which a light emitting element is mounted. The recess is defined by a sidewalls and a relatively thin membrane. At least two micro-vias are provided in the membrane and include conductive material that passes through the membrane. A p-contact of the light emitting element is coupled to a first micro-via and an n-contact of the light emitting element is coupled to a second micro-via. | 04-23-2009 |

20080315390 | Chip Scale Package For A Micro Component - A package includes a sensor die with a micro component, such as a MEMS device, coupled to an integrated circuit which may include, for example, CMOS circuitry, and one or more electrically conductive bond pads near the periphery of the sensor die. A semiconductor cap structure is attached to the sensor die. The front side of the cap structure is attached to the sensor die by a seal ring to hermetically encapsulate an area of the sensor die where the micro component is located. The bond pads on the sensor die are located outside the area encapsulated by the seal ring. Electrical leads, which extend along outer side edges of the semiconductor cap structure from its front side to its back side, are coupled to the micro component via the bond pads. | 12-25-2008 |
20110316015 | PACKAGE FOR A LIGHT EMITTING ELEMENT - A high-brightness LED module includes a substrate with a recess in which a light emitting element is mounted. The recess is defined by a sidewalls and a relatively thin membrane. At least two micro-vias are provided in the membrane and include conductive material that passes through the membrane. A p-contact of the light emitting element is coupled to a first micro-via and an n-contact of the light emitting element is coupled to a second micro-via. | 12-29-2011 |

20080274874 | SORBENT FOR THE DRY CLEANING OF WASTE GASES CHARGED WITH MERCURY AND PROCESS FOR THE PRODUCTION THEREOF - Sorbent for the dry cleaning of waste gases charged with mercury and process for the production thereof. The sorbent includes as an adsorptively acting constituent for example activated carbons or activated cokes which are mixed with sulfur in powder form at ambient temperature, under the action of atmospheric oxygen. The sorbent is distinguished by a given ratio in respect of the median values of the grain size of the adsorptively operative constituent to the sulfur. | 11-06-2008 |
20080289498 | PROCESS FOR THE PRODUCTION OF CARBONACEOUS ADSORPTION AGENTS DOPED WITH ELEMENTARY SULFUR AND A PROCESS FOR WASTE GAS CLEANING USING SUCH ADSORPTION AGENTS - The invention concerns a process for the production of carbonaceous adsorption agents doped with elementary sulfur, in which sulfur is mixed with the adsorption agent, the mixture is heated to a temperature of between 120° C. and 150° C. and the temperature is maintained over a period of about an hour. The process is distinguished in that heating of the mixture is effected under a controlled oxygen-bearing atmosphere. The invention further concerns a process for waste gas cleaning using carbonaceous absorption agents doped with elementary sulfur. Preferably brown coal coke is used as the adsorption agent. | 11-27-2008 |
