6307479	Running indicator for integrated circuit package A light emitting diode (LED) is connected in series with the power supply input pad of an integrated circuit chip. The LED lights up when the power supply is turned on as an indicator that the IC is operating properly....	10/23/2001
6291841	Flat interconnection semiconductor package Flat metal strips are used to make connections to a laser diode so that the interconnections are parallel to the surface of the semiconductor device and the structure has a lower profile than a wire-bonded package. The contacts can be made with conducting...	09/18/2001
6246555	Transient current and voltage protection of a voltage regulator During transient operation of a voltage regulator, the gate of p-channel MOS pass transistor may be pulled down during the transient period to cause excessive surge current. The surge current is limited by using the pass transistor as a current mirror dur...	06/12/2001
6008529	Laser diode package A surface mount semiconductor laser diode package has a substrate on which the laser diode is mounted. The top electrode of the laser diode is wire-bonded to the top end of a plated-through conduit through the substrate, and the bottom end of the plated-t...	12/28/1999
5888001	Paper tray for ink jet printer The collecting tray of a ink-jet printer is equipped with a guard to prevent the paper immediately after exiting from the printer to fall to the bottom of the tray. The guard is much narrower than the width of the tray so that the guard tilts the paper. A...	03/30/1999
5827780	Additive metalization using photosensitive polymer as RIE mask and part of composite insulator The surface of an integrated circuit, which uses reactive ion etching to pattern metal interconnection, is protected with two insulating layers on the surface.
