International Classification:

H01L 21/311
H01J 37/32

Abstract:

Methods and apparatus for etching a high aspect ratio feature in a stack on a substrate are provided. The feature may be formed in the process of forming a 3D NAND device. Typically, the stack includes alternating layers of material such as silicon oxide and silicon nitride or silicon oxide and polysilicon. WFis provided in the etch chemistry, which substantially reduces or eliminates problematic sidewall notching. Advantageously, this improvement in sidewall notching does not introduce other tradeoffs such as increased bowing, decreased selectivity, increased capping, or decreased etch rate.

Inventors:

Carlos Eduardo Escobar K'David - Rosharon TX, US

International Classification:

H04W 4/80
H04W 4/10

Abstract:

The present invention proposes a wireless wearable Push-To-Talk (PTT) device which is capable of enabling three or more short-range communication accessories. In specific, the wearable Push-To-Talk device can be connected to multiple short-range communication accessories such as a hearing accessory, a visual accessory and a Push-To-Talk control accessory through a second communication unit provided therein. A wireless transceiver is configured in said second communication unit to transmit or receive radio signals. The second communication unit and the wireless transceiver, support the Bluetooth communication between the Push-To-Talk system and other short-range communication accessories either simultaneously or individually. The Push-To-Talk device along with multiple short-range communication accessories assists the operator with an efficient and secured communication.
