Title: Hysteresis fuse control circuit with serial interface fusion
Inventor: MARSHALL ANDREW
IPC: G11C17/18
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To enhance voltage accuracy in a package by an arrangement wherein a feedback control circuit supplies current to an electrically fusible element and keeps the electrically fusible element in fusible state. SOLUTION: At the time of blowing out an electrically fusible element, i.e., a fuse F1 a feedback control circuit pulls the gate of a transistor N2 high and elevates the voltage at node A to turn a transistor P1 off and to turn a transistor N1 on. An output V2 is thereby pulled low and a transistor P2 is turned on to feed a current through the fuse F1 from a power supply VDD and to blow out the fuse F1 thus elevating the voltage at node A to the voltage level of the power supply VDD. Upon receiving a fusion signal, an inverter stage INV controls operation of the transistor P2 by feeding back the output voltage V2 thus keeping the fused state of the fuse F1.

Title: Manufacture of polyimide optical waveguide
Inventor: SHIODA TAKASHI
IPC: G02B6/13
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To make it possible to precisely control a film thickness by a dry method and a method which does not require precise temperature control by manufacturing a core layer by a plasma sputtering vapor deposition method. SOLUTION: A core layer is manufactured by the plasma sputtering vapor deposition method. A target in its general manufacturing method is the polyimide bulk manufactured in such a manner as to form desired polyimide and the growth is initiated by opening a shutter at the front surface of a substrate holder. Argon, nitrogen and a gaseous mixture composed thereof are conceivable as the gas used for the plasma. While the growth is possible even with a high- frequency parallel plate type as a type of the plasma, the use of high-density plasmas, which are electron cyclotron resonance and inductively coupled plasma, helicon wave excited plasma, etc., and are of the type in which the place of generation and a substrate are apart from each other, is more suitable for high speed uniform film formation. Since the polyimide thin film to be grown is determined by the target, there is no need for the temperature control, such as precise effusion cell, as in a vacuum vapor deposition method.
