Patent EP-1475826-A3 (EP)
Inventor: NAKAYAMA MASAHIRO
IPC: H01L21/304
Filed: 2003-10-23
Abstract: Nitride semiconductor wafers which are produced by epitaxially grown
nitride films on a foreign undersubstrate in vapor phase have strong inner
stress due to misfit between the nitride and the undersubstrate material. A
GaN wafer which has made by piling GaN films upon a GaAs undersubstrate
in vapor phase and eliminating the GaAs undersubstrate bends upward due to
the inner stress owing to the misfit of lattice constants between GaN and
GaAs. Ordinary one-surface polishing having the steps of gluing a wafer
with a surface on a flat disc, bringing another surface in contact with a lower
turntable, pressing the disc, rotating the disc, revolving the turntable and
whetting the lower surface, cannot remedy the inherent distortion. The
Distortion worsens morphology of epitaxial wafers, lowers yield of via-mask
exposure and invites cracks on surfaces. Nitride crystals are rigid but
fragile. Chemical/mechanical polishing has been requested in vain.
Current GaN wafers have roughened bottom surfaces, which induce
contamination of particles and fluctuation of thickness. 
     Circular nitride wafers having a diameter larger than 45mm are made
and polished. Gross-polishing polishes the nitride wafers in a pressureless 
state with pressure less than 60g/cm 2  by lifting up the upper turntable for
remedying distortion. Distortion height H at a center is reduced to H≤12µm.
Minute-polishing is a newly-contrived CMP which polishes the nitride wafers
with a liquid including potassium hydroxide, potassium peroxodisulfate and
powder, irradiates the potassium peroxodisulfate with ultraviolet rays. The
CMP-polished top surface has roughness RMS of 0.1nm≤RMS≤5nm or more
favorably 0.1nm≤RMS≤0.5nm. The CMP-polished bottom surface has
roughness RMS of 0.1nm≤RMS≤5000nm or more favorably 0.1nm≤RMS≤2nm.
TTV is less than 10µm.

IPC: H01M50/572
Filed: 1998-07-23
Abstract: A bypass apparatus and method for series connected energy storage devices. Each of the
energy storage devices coupled to a common series connection has an associated bypass unit
connected thereto in parallel. A current bypass unit includes a sensor which is coupled in
parallel with an associated energy storage device or cell and senses an energy parameter
indicative of an energy state of the cell, such as cell voltage. A bypass switch is coupled in
parallel with the energy storage cell and operable between a non-activated state and an
activated state. The bypass switch, when in the non-activated state, is substantially non-conductive
with respect to current passing through the energy storage cell, and when in the
activated state, provides a bypass current path for passing current to the series connection so
as to bypass the associated cell. An activation circuit controls activation of the bypass switch
by activating an activatable medium contained in a chamber of the apparatus. A voltage limiting
circuit coupled in parallel across the cell limits the voltage across the cell during
provision of the bypass.

Abstract: The present invention relates to a device and a method for detection of illicit
removal of electronic equipment. The device is arranged between a power supply
and the electronic equipment and comprises a first current-sensing element.
Detection of illicit removal is obtained by sensing the level of the current that flows

equipment, which signal is adapted to bounce and come back to the device.
Detection of illicit removal is obtained when sensed current is lower than a certain
predetermined level and the bounced signal is absent.

Abstract: A switching signal generator for a switching power supply employing a DC-DC
modulator has an adder, an integrator and a quantizer. A gate driver circuit is provided
upstream of a power switch element and receives a quantizer output. By feeding back a
gate driver circuit output to the adder of the ΔΣ-modulator, a large phase margin is
obtained at a high-frequency switching. The switching signal generator for the ΔΣ
- modulation type switching power supply has an improved direct-current transmission
linearity characteristic relative to direct-current input, and that is stably controllable and
of high efficiency. Furthermore, a DC-DC converter has an adder, an integrator and a
quantizer, the integrator having a mechanism for adjusting its gain. The gain-adjusting
mechanism receives a signal from a current flowing internally of the DC-DC converter, a
voltage internally of the converter, or a converter output voltage to control gain of the
integrator so that the amplitude of output voltage of the integrator is not saturated and a
comparator is capable of high-speed operation, a Δ Σ-modulation type DC-DC
converter is provided that is unlikely to undergo oscillation especially at a high sampling
frequency, and that produces a stable output voltage.

Abstract: Monitoring is made as to whether the serial number of header incorporated to the data sent to an RLC 15 after a decoding process is continuous. When it is determined as a result of monitoring for a predetermined period of time that no defect is present in the header numbers, a multi-path timing is detected by taking a correlation between the result of the detection and spread codes of received signals and a pilot signal. From this multi-path timing, a station, from which data are to be received in fingers, is determined for interrupting processes of de-spread, RAKE reception and decoding, thus reducing power consumed in the processes.
