摘要:
The present invention provides a novel method for increasing the amount of deuterium incorporated into trap sites of a transistor device during a deuterium passivation anneal by electrically pre-stressing the fabricated device prior to a deuterium anneal. The method of the present invention equally applies to SOI and CMOS technology. As a result, the incorporation of more deuterium during a deuterium anneal in the process flow reduces the number of undesirable trap sites.
摘要:
An information write-register embedded in an integrated circuit (IC) is made of a plurality of independently addressable gate-controlled components formed in an isolated p-well nested in a n-well. Gates over the p-well are positioned on an insulator geometrically formed so that it is susceptible locally to electrical conductivity upon applying an overstress voltage pulse, whereby binary information can be permanently encoded into the write-register. The overstress voltage pulse is applied between the gate and the p-well and is created when a write-enable pulse of predetermined polarity and duration is superposed by a p-well pulse of opposite polarity and shorter duration.

This invention relates to a method of depositing dielectric on a semiconductor substrate to form part of a capacitor. The method includes reactive sputtering a metal oxide layer from a target of metal onto the substrate wherein the support is biased to induce a DC voltage across the depositing dielectric as it forms. The voltage may be in the range of 200-300V.

A method for producing a dielectric layer on a substrate made of a conductive substrate material includes reducing a leakage current that flows through defects of the dielectric layer at least by a self-aligning and self-limiting electrochemical conversion of the conductive substrate material into a nonconductive substrate follow-up material in sections of the substrate that are adjacent to the defects. Also provided is a configuration including a dielectric layer with defects, a substrate made of a conductive substrate material, and reinforcement regions made of the nonconductive substrate follow-up material in sections adjacent to the defects.

A programmable interconnect structure and method of operating the same provides a programmable interconnection between electrical contacts. The interconnect includes material that has a reversibly programmable resistance. The material includes a molecular matrix with ionic complexes distributed through the molecular matrix. Application of an electrical field or electric current causes the molecular composite material to assume a desired resistivity (or conductivity) state. This state is retained by the molecular composite material to thus form a conductive or a non-conductive path between the electrical contacts.

A surface PIN (SPIN) device and a method of fabricating such a SPIN device. The SPIN device, when activated, confines carrier injection to a small volume near the surface of the device such that the device is sufficiently conductive to simulate a planar conductor. The SPIN device comprises a Pnull region and an Nnull region formed in an intrinsic (I) layer. The Pnull and Nnull regions are separated by a lateral length of intrinsic material of length L. The length L is approximately the carrier diffusion length. When DC bias is applied across the Nnull and Pnull regions carriers are injected into the intrinsic region at a density exceeding 1018 carriers per cubic cm. The intrinsic region is sufficiently thin to confine the carriers near the surface of the intrinsic region. As such, in the nullonnull state, the SPIN device simulates a conductive material. In the nulloffnull state, the SPIN device is no longer conductive. Consequently, a planar array of SPIN devices can be fabricated and selectively activated to form a dynamic, reconfigurable antenna.

A method includes (a) putting a multielectrodic chip lithographed in a wafer that contains between 2 and 2000 individually polarisable electrodes, in contact with a solution or suspension that includes modified colloidal particles with a (bio)chemical recognition element; (b) applying to an electrode of the multielectrodic chip, a potential between null1 and null2V vs. Ag/AgCl saturated, for a period of time between 1 and 300 seconds; (c) washing the chip after this stage (b); and (d) repeat the steps (b) and (c) as many times as needed to deposit a (bio)chemical recognition element, same or different to the one or ones previously deposited, on each one of the electrodes of that chip. The method is applicable for the fabrication of multisensors, particularly in chips and arrays for analytical and diagnostic applications.
摘要:
A method for operating a P-channel SONOS memory device that has a charge trapping layer located on a substrate, a gate electrode located on the trapping layer, two doped regions located in the substrate at each side of the charge trapping layer. The two doped regions are set to be a drain region and a source region. When a programming action is intended, the gate electrode and the drain region are applied with a first negative high-level bias, and the source region and the substrate are applied with a grounded voltage. When an erasing action is intended, the gate electrode is a second negative bias which is smaller than the first negative voltage in absolute value. In the mean time, the drain region is applied with the third negative bias and the substrate is applied with a grounded voltage. The third negative voltage is larger than the second negative bias in absolute value.

A cleaning method for semiconductor manufacturing process. A to-be-cleaned wafer having a metal layer thereon is provided. The wafer is placed into a chemical cleaning equipment unit to clean the wafer surface with a chemical cleaning solution while protecting the metal layer by a cathodic protection method. Next, the chemical cleaning solution on the wafer surface is rinsed away and the wafer is then dried to complete the cleaning method.
