Patent DE-4331895-A1 (DE)
Title: Reference voltage clamping circuit e.g. for semiconductor memory - uses constant current circuit to supply reference voltage to clamping transistor control electrode
Inventor: KAJIMOTO TAKESHI
IPC: H01L27/10
Filed: 1993-09-20
Abstract: The voltage clamping circuit has a reference voltage generator connected between a reference potential terminal and the clamping terminal (200), for providing a reference voltage which differs from the reference potential supplied to the reference potential terminal. A clamping transistor (1) receives the reference voltage. Pref. the reference voltage generator uses a constant current circuit with a constant current source (5), a current reflector (3,4) and a trimmable resistance (4) across which a voltage is obtained which is fed to the gate of the clamping MOSFET. USE/ADVANTAGE - E.g. for DRAM etc. Improved current/voltage characteristic.

Title: Winding arrangement
Inventor: MUELLER WALTER DR ING
IPC: H01F27/36
Filed: 1993-09-29
Abstract: In order to make the electrostatic fringe field (edge field, boundary field) of windings (5, 7) uniform in the case of transformers, it is proposed to arrange conductive inserts (17a, 17b) concentrically in the end region of the windings (5, 7). The electrostatic fringe field is homogenised by the conductive inserts (17a, 17b), which in turn results in the insulation cost being reduced. The conductive inserts (17a, 17b) are preferably arranged in the fringe region of the windings (5, 7) by means of solid insulation (15), the distance between the respective conductive inserts (17a, 17b) being the same. <IMAGE>

Title: Method for producing a high-melting metal silicide in a semiconductor component
Inventor: LEE NAE-IN
IPC: H01L23/52
Filed: 1994-07-18
Abstract: It is known to use high-melting metal silicides as low-resistance electrical connections in semiconductor components by producing the latter by solid-state reaction of a high-melting metal layer with an impurity-doped polysilicon layer. It is proposed to use, as the underlying silicon layer which reacts with a high-melting metal layer (44), applied thereon, for forming the high-melting metal silicide, an impurity-doped amorphous silicon layer produced by using an in situ doping process, or a double-layer structure, consisting of a lower impurity-doped silicon layer (42) and an overlying, undoped silicon layer (43). In this way, a high-melting metal silicide can be obtained with an even surface, which is thermally stable because of reduced silicide agglomeration.
