Title: Method of reducing RIE lag for deep trench silicon etching
Inventor: NAEEM MUNIR D
IPC: H01L21/302
Filed: 2001-05-31
Granted: 2002-07-21
Abstract: A method of minimizing RIE lag (i.e., the neutral and ion fluxes at the bottom of a deep trench (DT) created during the construction of the trench opening using a side wall film deposition) in DRAMs having a large aspect ratio (i.e., >30:l) is described. The method forms a passivation film to the extent necessary for preventing isotropic etching of the substrate, hence maintaining the required profile and the shape of the DT within the substrate. The RIE process described provides a partial DT etched into a substrate to achieve the predetermined depth. The passivation film is allowed to grow to a certain thickneass still below the extent that it would close the opening of the deep trench. Alternatively, the passivation film is removed by a non-RIE etching process. The non-RIE process that removes the film can be wet etched with chemicals, such as hydrofluoric acid (buffered or non buffered) or, alternatively, using vapor phase and/or non-ionized chemicals, such as anhydrous hydrofluoric acid. The controlled thickness of the film allows achieving a predetermined DT depth for high aspect ratio structures.

Granted: 2002-12-11
Abstract: High quality epitaxial layers of compound semiconductor materials (26) can be grown overlying large silicon wafers (22) by first growing an accommodating buffer layer (24) on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer (28) dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer.

Abstract: An electronic stabilizer capable of reducing filament current after a fluorescent lamp tube is started is disclosed in the present invention. In the electronic stabilizer circuit, the devices required for starting the lamp tube and preheating the filament are in parallel with one side of the lamp tube far away from the power supply terminal. The resonant devices required after starting the lamp tube are in parallel with one side of the lamp tube near the power supply terminal so as to provide filament current for preheating the filament when the circuit starts the lamp tube. In addition, after starting the lamp tube, the filament current is properly reduced or removed to avoid the loss of filament current and energy waste. Therefore, the filament loss can be reduced so as to extend lifetime of lamp tube.

Abstract: A clock signal is supplied from a clock oscillator to a gate circuit. In a period in which a reset signal is at the ""H"" level, the clock signal is supplied to an internal circuit. When the reset signal becomes at the ""L"" level, a control is performed by a gate control circuit so as to stop the supply of the clock signal. Consequently, even when a delay signal in the internal circuit becomes longer than one cycle of the clock signal, occurrence of an erroneous operation can be prevented.
