Title: Trench-gate field-effect transistors and their manufacture
IPC: H01L21/336
Filed: 2000-11-17
Abstract: Trench-gate field-effect transistors, for example power MOSFETs, are disclosed having trenched electrode configurations (11,23) that permit fast switching of the transistor, while also providing over-voltage protection for the gate dielectric (21) and facilitating manufacture. The gate electrode (11) comprising a semiconductor material of one conductivity type (n) is present in an upper part of a deeper insulated trench (20,21) that extends into a drain region (14,14a) of the transistor. A lower electrode (23) connected to a source (13,33) of the transistor is present in the lower part of the trench. This lower electrode (23) comprises a semiconductor material of opposite conductivity type (p) that adjoins the semiconductor material of the gate electrode (11) to form a p-n junction (31) between the gate electrode (11) and the lower electrode (23). The p-n junction (31) provides a protection diode (D) between the gate electrode (11) and the source (13,33). The gate electrode (11) is shielded from most of the drain region by the lower electrode (23), so reducing the gate-drain capacitance and improving the switching speed of the transistor.

Title: Gain control in optical amplifiers
IPC: H04B10/29
Filed: 2001-02-20
Abstract: An optical amplifier arrangement is provided that includes an amplifier (10) elements for measuring the gain applied to the total input power (21, 31, 40) and a control unit (50) adapted to determine the degree of variation of gain with wavelength, i.e. the gain tilt, on the basis of a measurement of total gain. This is achieved by using a predetermined relationship between the wavelength dependent gain variation and total gain. This relationship is determined on production by measurement of the amplifier or of a batch or class of amplifiers. In this way a precise figure for gain tilt is provided for each amplifier. This may be used to eliminate gain tilt. Alternatively, if the system requirements tolerate limited gain tilt, the figure may be used to monitor the system. <IMAGE>
