METHOD FOR FORMING SELF-TRANSFORMED SUPPORT PLATES IN SHALLOW TRENCH ISOLATION FOR ADVANCED SEMICONDUCTOR DEVICES
The present invention provides a method for forming self-transformed support plates in shallow trench isolation for advanced semiconductor devices, in which after a photolithography process to define active areas on a silicon substrate, an additional photomask is implemented to add a support plate patterning layer in areas where silicon will be etched during a STI etching step to form STI trenches. Tiny silicon support plates inside the STI trenches are formed after the silicon etching. These silicon support plates may provide mechanical support to hold neighboring patterned strips where the active areas are defined or neighboring active areas islands, and preventing them from bending, deformed or shifting. An alignment of photomask pattern at following photolithography process is eased.
REACTOR TO FORM FILMS ON SIDEWALLS OF MEMORY CELLS
Apparatus and methods related to forming films on sidewalls of memory cell stacks in memory and logic devices. In one approach, a silicon wafer is held in a chamber of an atomic layer deposition (ALD) reactor. A temperature in the reactor is controlled to a first temperature (e.g., room temperature or below) where a first gas reactant that is provided into the chamber condenses and is adsorbed on the target wafer or substrate. The first reactant or precursor is partly vaporized at a second temperature in the reactor that is greater than the first temperature. A second gas reactant is provided into the chamber. The second gas reactant reacts with the adsorbed portion of the first gas reactant in its activated state. The reaction product is a film on the sidewall of a memory cell stack or logic devices. The foregoing steps are repeated to form a desired thickness of the film.
