Abstract:
1. A method for fabricating non-volatile storage, comprising: forming a first NAND string of non-volatile storage elements on a well; forming a first bit line contact in said well for said first NAND string of non-volatile storage elements between a drain side select gate for the first NAND string and a source side select gate for a second neighbor NAND string; forming a first source line contact in said well for said first NAND string of non-volatile storage elements between a source side select gate for the first NAND string and a drain side select gate for a third neighbor NAND string; forming a first bit line that connects to said first bit line contact without protruding into said well; and intentionally forming a source line that extends into said first source line contact and extends into said well.
