Title: Plasma enhanced chemical vapor deposition of films for improved vertical etch performance in 3d nand memory devices
Inventor: JHA PRAKET P
IPC: H01L21/02
Filed: 2016-03-16
Granted: 2022-06-01
Abstract: Implementations of the present disclosure generally relate to thin films incorporating high aspect ratio feature definitions and methods for forming the same. As gate height increases, 3D NAND gate stacks are subject to higher aspect ratio etching. Due to the current limitations of etching techniques, the vertical etch profile typically tapers as the depth into the gate stack increases. The inventors have devised a unique deposition scheme that compensates for etch performance degradation in deep trenches by a novel plasma-enhanced chemical vapor deposition (PECVD) film deposition method. The inventors have found that by grading various properties (e.g., refractive index, stress of the film, dopant concentration in the film) of the as-deposited films (e.g., silicon nitride) a more uniform etch profile can be achieved by compensating for variations in both dry and wet etch rates.

Title: Pulse modulator and pulse modulation method
Inventor: GUENTER SPAHLINGER
IPC: H03K/
Filed: 2005-10-12
Abstract: A pulse modulator has a subtraction stage that produces a control error signal from the difference between a complex input signal and a feedback signal. A signal conversion stage converts the control error signal to a control signal. The control signal is multiplied by a complex mixing signal at the frequency omega0 in a first multiplication stage. At least one of the real and imaginary parts of the up-mixed control signal is then quantized by a quantization stage to produce a real pulsed signal. The pulsed signal is then employed to produce the feedback signal for the subtraction stage in a feedback unit. The pulse modulator according to the invention allows the range of reduced quantization noise to be shifted toward a desired operating frequency omega0.

Title: Methods and apparatuses for pump sealing during leakage events.
Inventor: JOHN R BASS
IPC: G21C13/10
Filed: 2012-12-14
Abstract: A pump leakage mitigation device includes one or more clamp arms on an outer surface of a pump that can be driven by a biasing element to seat against a shaft of the pump to seal or reduce fluid flow through a breakdown of the pump. The biasing element engages only at threshold temperatures, such as those associated with breakdown orifice failure when additional sealing may be necessary. Clamp arms of any number and shape can be used to achieve the desired seal and based on the pump geometry. A sealant surface and/or keeping mechanism are useable with the leakage mitigation device to enhance fluid flow blockage throughout a pump failure transient scenario. Pump leakage mitigation devices are installed on an outside of a variety of different pump types and can thus be installed, actuated, manipulated, disengaged, and/or removed without having to destroy or disassemble the pump.

Title: Electricity meter hot socket detection.
Inventor: SHUEY KENNETH C
IPC: G01R31/02
Filed: 2014-04-30
Abstract: When a poor meter to socket connection occurs, there is the potential for arcing to develop which can result in a hot socket and a fire. Disclosed herein are methods for a meter to detect the occurrence of an arc condition in the socket by analyzing the RF noise on the channels of the communication spectrum used by the meter to communicate within its metering system. For example, by keeping a record of the normal background noise and looking for a broadband increase in the noise on all channels, arc detection can be achieved. Meter quantities such as temperature, current, voltage, and harmonic content may also be used in a standalone manner or in combination with broadband RF noise to detect an arc condition. A disconnect switch within the meter can be opened to remove the arc fault.
