Patent TW-413961-B (TW)
Title: Fabrication of green-blue-white amorphous p-I-n thin-film light-emitting diodes
Inventor: HUNG JR-WANG
IPC: H01L33/00
Filed: 1998-11-25
Granted: 2000-12-01
Abstract: The light-emitting layer of an amorphous p-i-n thin-film light-emitting diode is its p-i interface. In order to improve the brightness of this device and lower its operating voltage, continuously-deposited new graded-gap p-i and i-n junction structures were employed to obtain the better junction interfaces, and lower the nonradiative trap density in the interfaces, device internal resistance and ohmic-contact resistances of external electrodes. Since a high optical-gap material, such as a-SiN:H, a-SiO:H, a-CN:H, a-SiCN:H or a-C:H was used for the i-layer in the proposed device, most of the applied voltage would drop across the i-layer and result in an enhanced electric field in this i-layer. This enhanced electric field would thus allow carriers to be injected into the higher energy states in the i-layer. Accordingly, theradiative recombinations of electrons and holes, which have the larger energy difference, would cause green, blue or white light emissions, having higher photon energy. The traditional amorphous p-i-n thin-film light-emitting diode has many defects at its p-i and i-n interfaces. Also, since the optical-gap of i-layer is higher than those of the n- and p- layers, there are conduction and valence band offsets at p-i and i-n interfaces which would retard electron and hole injections into the light-emitting p-i interface. So the optoelectronic characteristics of a traditional device, such as brightness, needed applied voltage and stability, are poorer than those of the ones proposed by this invention.

Title: Method and apparatus for measuring substrate layer thickness during chemical mechanical polishing
Inventor: WISWESSER ANDREAS NORBERT
IPC: B24B37/04
Filed: 1999-09-22
Granted: 2001-05-01
Abstract: The thickness of a layer on a substrate is measured in-situ during chemical mechanical polishing. A light beam is divided through a window in a polishing pad, and the motion of the polishing pad relative to the substrate causes the light beam to move in a path across the substrate surface. An interference signal produced by the light beam reflecting off the substrate is monitored, and a plurality of intensity measurements are extracted from the interference signal. Each intensity measurement corresponds to a sampling zone in the path across the substrate surface. A radial position is determined for each sampling zone, and the intensity measurements are divided into a plurality of radial ranges according to the radial positions. The layer thickness is computed for each radial range from the intensity measurements associated with that radial range.

Title: Local penetrating proton beam transmutation doping method for silicon
Inventor: LIAU JUNG-BIN
IPC: H01L21/26
Filed: 1999-12-17
Granted: 2001-05-28
Abstract: Efficient transmutation doping of silicon through the bombardment of silicon wafers by a beam of protons is described. A key feature of the invention is that the protons are required to have an energy of at least 4 MeV to overcome the Coulomb barrier. When this is done, transmutationally formed phosphorus in concentrations as high as 10<SP>16</SP> atoms per cc. are formed from proton beams having a dosage as low as 10<SP>19</SP> protons per square cm, therefore the required ion doping time is very short. As a byproduct of the process, sulfur is also formed in a practical concentration range of about 10<SP>13</SP> atoms per cc. This is readily removed by annealing at temperatures of the order of 700 DEG C. Because of the high energy of the protons, several silicon wafers may be processed simultaneously. As expected, the additional phosphorus is uniformly deposited throughout the passage of the proton. Masks, either freestanding or contact, may also be used in order to limit the transmuted regions to the particular desired areas.
