Backside nanoscale texturing to improve IR response of silicon solar cells and photodetectors

Номер: US20120080676A1

Принадлежит: SiOnyx LLC

The absorption coefficient of silicon for infrared light is very low and most solar cells absorb very little of the infrared light energy in sunlight. Very thick cells of crystalline silicon can be used to increase the absorption of infrared light energy but the cost of thick crystalline cells is prohibitive. The present invention relates to the use of less expensive microcrystalline silicon solar cells and the use of backside texturing with diffusive scattering to give a very large increase in the absorption of infrared light. Backside texturing with diffusive scattering and with a smooth front surface of the solar cell results in multiple internal reflections, light trapping, and a large enhancement of the absorption of infrared solar energy.

Programmable fuse and antifuse and method therefor

Номер: US20040114433A1
Автор: Leonard Forbes
Принадлежит: Micron Technology Inc

P-channel MOSFET devices are used as reprogrammable fuse or antifuse elements in a memory decode circuit by utilizing anomalous hole generation. An applied negative gate bias voltage is sufficiently large to cause tunnel electrons to gain enough energy to exceed the band gap energy of the oxide. This causes energetic hole-electron pairs to be generated in the silicon substrate. The holes are then injected from the substrate into the oxide, where they remain trapped. A large shift in the threshold voltage of the p-channel MOSFET results. The device can subsequently be reset by applying a positive gate bias voltage. Various circuits incorporating such fuse or antifuse elements are also disclosed.

Methods and apparatus for making integrated-circuit wiring from copper, silver, gold, and other metals

Номер: US6756298B2
Автор: Kie Y. Ahn, Leonard Forbes
Принадлежит: Micron Technology Inc

In recent years, copper wiring has emerged as a promising substitute for the aluminum wiring in integrated circuits, because copper offers lower electrical resistance and better reliability at smaller dimensions than aluminum. However, use of copper typically requires forming a diffusion barrier to prevent contamination of other parts of an integrated circuit and forming a seed layer to facilitate copper plating steps. Unfortunately, conventional methods of forming the diffusion barriers and seed layers require use of separate wafer-processing chambers, giving rise to transport delays and the introduction of defect-causing particles. Accordingly, the inventors devised unique wafer-processing chambers and methods of forming barrier and seed layers. One embodiment of the wafer-processing chamber includes equipment for physical vapor deposition and equipment for chemical vapor deposition to facilitate formation of diffusion barriers and seed layers within one chamber, thereby promoting fabrication efficiency and reducing defects.

Methods for making copper and other metal interconnections in integrated circuits

Номер: US6984891B2

Принадлежит: Micron Technology Inc

A typical integrated-circuit fabrication requires interconnecting millions of microscopic transistors and resistors with aluminum wires. Yet, aluminum wires have greater electrical resistance and are less reliable than copper wires. Unfortunately, current techniques for making copper wires are time-consuming and inefficient. Accordingly, the invention provides a method of making wires or interconnects from copper or other metals. One embodiment entails forming a first diffusion barrier inside a trench using ionized-magnetron sputtering for better conformal coating of the trench, and a second diffusion barrier outside the trench using jet-vapor deposition. The jet-vapor deposition has an acute angle of incidence which prevents deposition within the trench and thus eliminates conventional etching steps that would otherwise be required to leave the trench free of this material. After formation of the two diffusion barriers, the trench is filled with metal and annealed.

Efficient CMOS DC-DC converters based on switched capacitor power supplies with inductive current limiters

Номер: US6429632B1
Автор: Kie Y. Ahn, Leonard Forbes
Принадлежит: Micron Technology Inc

A novel class of DC to DC power converters and a method of conversion is provided using high-frequency switched capacitors where the switches are implemented by CMOS transistors or diodes on an integrated-circuit chip and using inductors to limit charging current. High efficiency is achieved using inductors to reduce energy losses in circuit capacitors by high frequency switching when inductor current is zero and capacitor voltage is maximized. The high-frequency (100 MHz or greater) operation of the converter circuit permits the use of inductors with a low inductance value on the order of 100 nH (100×10 −9 Henrys) capable of fabrication directly on an integrated-circuit (IC) chip. The use of CMOS integrated components allows the entire converter to be formed on a single IC chip, saving significant space within the portable system. Output voltage and current is high enough to permit EEPROM programming. In addition, fluctuations in the output voltage (ripple voltage) are substantially eliminated when several of the converter circuits are used in parallel.
