Title: Insulation layer and method of forming it
Inventor: SOMUNASU ESU NAGU
IPC: H01L29/78
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To remove accumulated charges to prevent an oxide film of a transistor gate from being physically broken by forming a first common sublayer made of a first insulation material on the surface and protrusions by the plasma enhanced deposition and a second planar sublayer made of a second insulation material thereon. SOLUTION: A Si substrate 102 having poly-Si gates 104-106, poly-Si line 108 and sources/drains 134-136 is fed in a high-density plasma reactor to deposit low-bias oxide films 202 by the plasma enhanced deposition. The gates 104-106 and antenna formed by the line 108 form a high electric field between the gate oxide films. This avoids connecting charges enough to deteriorate the performance of a transistor. High-bias oxide films 204 are deposited.
