Title: Low leak dram cell and its formation
Inventor: YOHAN ARUSUMAIAA
IPC: H01L29/786
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To achieve a more economical and improved method for reducing or eliminating the leakage current of a DRAM by using an SOI substrate for manufacturing a DRAM cell by a trench technique and preventing dislocations around the trench. SOLUTION: A MOS transistor is completely insulated from the outer periphery of trenches 44 and 46 and is reinforced, so that it is not affected by any dislocation for the trenches 44 and 46 in its operation, and a treatment stage can be simplified. Also, a DRAM 60 is not capable of any vertical transistor operation, due to the use of an oxide that is subjected to radiation curing and embedded or a strap 56, thus obtaining V plate operation at 0 V in certain applications for allowing a lightly-doped SOI substrate 36. As a result, a CMOS switching operation for eliminating a latchup problem does not affect the DRAM 60, thus achieving a more economical and improved method for reducing or eliminating the leakage current of the DRAM.
