Abstract: In some embodiments, a system is disclosed for delivering hydrogen peroxide to a semiconductor processing chamber. The system includes a process canister for holding a H2O2/H2O mixture in a liquid state, an evaporator provided with an evaporator heater, a first feed line for feeding the liquid H2O2/H2O mixture to the evaporator, and a second feed line for feeding the evaporated H2O2/H2O mixture to the processing chamber, the second feed line provided with a second feed line heater. The evaporator heater is configured to heat the evaporator to a temperature lower than 120° C. and the second feed line heater is configured to heat the feed line to a temperature equal to or higher than the temperature of the evaporator.

Abstract: In some embodiments, a reactive curing process may be performed by exposing a semiconductor substrate in a process chamber to an ambient containing hydrogen peroxide, with the pressure in the process chamber at about 300 Torr or less. In some embodiments, the residence time of hydrogen peroxide molecules in the process chamber is about five minutes or less. The curing process temperature may be set at about 500° C. or less. The curing process may be applied to cure flowable dielectric materials and may provide highly uniform curing results, such as across a batch of semiconductor substrates cured in a batch process chamber.

Abstract: In some embodiments, an oxide layer is grown on a semiconductor substrate by oxidizing the semiconductor substrate by exposure to hydrogen peroxide at a process temperature of about 500° C. or less. The exposure to the hydrogen peroxide may continue until the oxide layer grows by a thickness of about 1 ? or more. Where the substrate is a germanium substrate, while oxidation using H2O has been found to form germanium oxide with densities of about 4.25 g/cm3, oxidation according to some embodiments can form an oxide layer with a density of about 6 g/cm3 or more (for example, about 6.27 g/cm3). In some embodiments, another layer of material is deposited directly on the oxide layer. For example, a dielectric layer may be deposited directly on the oxide layer.

Abstract: Memory cell structures and related circuitry for use in non-volatile memory devices can be fabricated utilizing standard CMOS processes, for example, 0.18 micron or 0.15 micron processes. Advantageously, the cell structures can be programmed so that a conductive path is formed between like type materials, for example, between a p-type gate and a p-type source/drain region or an n-type gate and an n-type source/drain region. Programming cells in this manner advantageously provides a programmed cell having a low, linear resistance after programming.

Abstract: Memory cell structures and related circuitry for use in non-volatile memory devices are described. The cell structures can be fabricated utilizing standard CMOS processes, e.g. sub 0.35 micron or sub 0.25 micron processes. Preferably, the cell structures can be fabricated using 0.18 micron or 0.15 micron standard CMOS processes. Advantageously, the cell structures can be programmed so that a conductive path is formed between like type materials. For example, in certain cell structures a cell is programmed by applying a programming voltage in such a way as to form a conductive path between a p-type gate and a p-type source/drain region or an n-type gate and an n-type source/drain region. Programming cells in this manner advantageously provides a programmed cell having a low, linear resistance after programming. In addition, novel charge pump circuits are provided that, in a preferred embodiment, are located “on chip” with an array of memory cells.
