Title: Modulator and method for manufacturing of such a modulator
Inventor: LUNDQVIST LENNART
IPC: G02F1/015
Filed: 1998-10-23
Granted: 2001-01-11
Abstract: electro-absorption modulator (EAM), of the kind that includes a waveguide, for modulation of light, comprising a waveguide core, a waveguide cladding (42, 43, 52, 53), and an electrode (45, 55), the modulator being arranged to modulate light launched into the modulator as a response to a voltage being applied on the electrode. According to the invention, the width and/or the thickness of the waveguide core (41, 51) are/is varying along the length of the modulator. Particularly, the variation is arranged to achieve a mainly uniform photo current distribution and thus temperature distribution along the modulator, for the purpose of reducing the thermally dependent, optical rise time of the modulator. Preferably, the width/thickness is smaller in the part of the modulator where the light is intended to be input, for the purpose of reducing the absorption of the modulator there. A method in manufacturing of the modulator utilizes a tapered photolithography mask (46).

Title: Transmitter of electromagnetic field three-dimensional positioning system
Inventor: SHR SHR-JIUN
IPC: G06F3/033
Filed: 1998-11-26
Granted: 2001-10-01
Abstract: The present invention relates to a transmitter of electromagnetic field three-dimensional positioning system. The system installs the receiving coil of receiver in the object to be tested. The transmitter incorporated with the transmitting coils x, y and z are provided to emit electromagnetic field. The receiver incorporated with the receiving coils x, y and z are provided to receive electromagnetic signal. The receiver amplifies the signal and converts the same into digital binary data, which is then sent to the DSP to be processed. Therefore, the system can use a positioning and tracing receiver built-in with the DSP to determine the position of the tested object. When the receiving coils x, y and x are close to the transmitting coordinate axes x, y and z, the transmitter changes the electromagnetic field emitted by the transmitting coils x, y and z. That is, the transmitting coordinate axes are changed to increase the precision in tracing and positioning.

Title: Oxygen enhancement of ion metal plasma (IMP) sputter deposited barrier layers
Inventor: KIM EDWIN
IPC: C23C14/08
Filed: 1999-02-24
Granted: 2001-02-21
Abstract: The present disclosure pertains to our discovery that depositing various film layers in a particular order using a combination of Ion Metal Plasma (IMP) and traditional sputter deposition techniques with specific process conditions results in a barrier layer structure which provides excellent barrier properties and allows for metal/conductor filling of contact sizes down to 0.25 micron and smaller without junction spiking. Specifically, the film layers are deposited on a substrate in the following order: (a) a first layer of a barrier metal (M), deposited by IMP sputter deposition; (b) a second layer of an oxygen-stuffed barrier metal (MOx), an oxygen-stuffed nitride of a barrier metal (MNOx), or a combination thereof; (c) a third layer of a nitride of a barrier metal (MNx), deposited by IMP sputter deposition of the barrier metal in the presence of nitrogen; and (d) a fourth, wetting layer of a barrier metal, deposited by traditional sputter deposition. The first layer of barrier metal can optionally be annealed to form a silicide of the barrier metal (MSi2) in order to reduce contact resistance and interdiffusion of the silicon and metal/conductor which may result from overetching of contacts. An additional layer of barrier metal can optionally be deposited between the second oxygen-stuffed layer and the third barrier metal nitride layer in order to further improve the barrier properties of the barrier layer structure and to provide for better metal/conductor fill. A thin layer of metal/conductor may be deposited on the walls of the contact via by ""long throw"" sputter deposition prior to filling the via with metal/conductor in order to provide more uniform fill. The optimum process conditions for sputter deposition of the barrier layer structure of the invention are disclosed herein.
