Title: Trench fill with HDP-CVD process
Inventor: ROSSMAN KENT
IPC: H01L21/768
Filed: 2001-05-03
Granted: 2002-09-11
Abstract: A trench-fill material is deposited to fill a trench in a substrate disposed in a process chamber. An inert gas is introduced into the process chamber and a plasma is formed to heat the substrate to a preset temperature, which is typically the temperature at which deposition of the trench-fill material is to take place. The plasma is terminated upon reaching the preset temperature for the substrate. A process gas is then flowed into the process chamber without plasma excitation until the process gas flow and distribution achieve a generally steady state in the process chamber. A plasma is then formed to deposit the trench- fill material on the surface of the substrate and fill the trench. By establishing generally steady state conditions in the chamber prior to deposition, transient effects are reduced and more uniform deposition of the trench-fill material is obtained. The step of forming the plasma typically includes coupling source plasma energy into the process chamber at a total power density of at least about 15 Watts/cm<SP>2</SP>. The energy is inductively coupled into the process chamber by coupling a top coil with a top portion of the process chamber above the surface of the substrate and coupling a side coil with a side portion of the process chamber generally surrounding the side edge of the substrate. The top coil is powered at a top RF power level to produce a top power density and the side coil is powered at a side RF power level to produce a side power density. The total RF power density is equal to the sum of the top and side power densities. The top power density and the side power density desirably have a ratio of at least about 1.5. The high source plasma power density generates a high ion density plasma and produces a more directional deposition, and a higher top power density relative to the side power density produces a more uniform plasma over the substrate, resulting in improved trench fill, particularly for aggressive trenches having aspect ratios of about 3:1 to 4:1. The process gas typically includes silicon, oxygen, and an inert component having a concentration of less than about 40%, by volume. In specific embodiments, the concentration of the inert component is equal to about 0%.
