Title: Method of forming interconnect structure with organic polymer sidewall spacer
Inventor: TSENG HORNG-HUEI
IPC: H01L27/105
Filed: 1996-06-26
Granted: 1999-12-21
Abstract: This invention discloses a method of forming interconnect structure with organic polymer sidewall spacer, the steps including: (1) forming a polysilicon layer on gate layer across contact holes after a MOSFET is obtained; (2) forming vertical opening on the polysilicon layer; (3) immediately forming an organic polymer sidewall spacer in plasma etching reaction chamber after the (2) step; (4) etching away the remaining polysilicon material, then using the organic polymer sidewall spacer by the side of vertical opening as protective mask, to form a ladder-shaped opening at the cut away portion of polysilicon layer. Since the width at the bottom of ladder opening is less than the photolithograph limit, this can prevent creation of dishing on the surface of silicon wafer due to photo misalignment in the semiconductor manufacturing process. This method thus solves the problem of current cut off and junction short on MOSFET ICs.

If this testing identifies faulty memory rows in the memory array at any time, the electrically programmable memory elements can be internally re-programmed to create a new memory configuration which includes redundant memory rows. This new memory configuration is enabled in order to remove the newly-detected and previously-detected faulty memory rows from active memory in the memory array.

Title: Electrical choke for power factor correction
Inventor: COLLINS ALIKI
IPC: H01F37/00
Filed: 1998-05-20
Granted: 1999-07-11
Abstract: An electrical choke comprises a magnetic amorphous metal core having, in combination, a distributed gap and a discrete gap. The amorphous metal is an iron based, rapidly solidified alloy. The distributed sap configuration is achieved by subjecting the magnetic core to a heat treatment, causing partial crystallization of the amorphous alloy. Such partial volume crystallization reduces the permeability of the magnetic core from several thousands to a value ranging from 200 to 800. The discrete gap is introduced by cutting the core and inserting a spacer. Depending on the width of the gap and the value of the annealed permeability, effective permeabilities in the range of 200 to 40 can be achieved. Advantageously, the reduced permeability magnetic core maintains its initial permeability under DC bias field excitation and exhibits low core loss, making it especially suited for use in power factor correction applications.
