Latest Patent Applications

1. **INTEGRATED CIRCUIT DEVICE AND ELECTRONIC SYSTEM INCLUDING THE SAME** - This application describes a cell array structure of an integrated circuit device. It includes a gate stack with gate electrodes and mold insulation layers that extend horizontally and are alternately stacked vertically. The channel structure extends vertically in the gate stack and includes a channel layer and a gate insulation layer that conformally covers the channel layer. The design exposes a portion of the upper surface of the channel layer, with an insulation pattern layer disposed on the gate stack. A common source line structure contacts the gate insulation layer, the insulation pattern layer, and the upper surface of the channel layer, featuring a staircase-shaped sidewall.

2. **NON-VOLATILE MEMORY DEVICE AND ELECTRONIC SYSTEM INCLUDING THE SAME** - This application outlines a non-volatile memory device that includes a substrate with a first cell region, a second cell region, and a connection region between them. The mold structure features a plurality of gate electrodes stacked in a stepped pattern. A trench along the profile of the mold structure includes a bottom surface with a stair shape and a first sidewall. The design incorporates a liner film on the first sidewall of the trench, a recess exposing a pad portion of a gate electrode, and a cover insulating layer provided at the trench. The liner film has a different etch selectivity compared to the cover insulating layer.
