Method of forming trench isolation regions

A method of forming a trench isolation region comprising:

• forming an isolation trench within semiconductive material of a semiconductive substrate;
• providing a silicon comprising electrically insulative aspect ratio lowering material within the isolation trench to partially fill the isolation trench, said providing comprising a liquid deposition within the isolation trench;
• and
• after providing the silicon comprising insulative aspect ratio lowering material, depositing an initially solid silicon comprising electrically insulative material within the isolation trench over the insulative aspect ratio lowering material.

A method of forming a trench isolation region comprising:

• forming an isolation trench within semiconductive material of a semiconductive substrate;
• providing a material of a first composition within the isolation trench which partially fills the isolation trench and lowers an aspect ratio of the isolation trench from what is was prior to said providing;
• converting the first composition to a second composition which partially fills the isolation trench and is electrically insulative;
• and
• after the converting, depositing an electrically insulative material within the isolation trench over the converted material.

A method of forming a trench isolation region comprising:

• etching an isolation trench within semiconductive material of a semiconductive substrate;
• forming an oxide layer over sidewall portions of the isolation trench;
• after forming the oxide layer, flowing a liquid material to within the isolation trench;
• solidifying the liquid material to an electrically insulative solid;
• providing the electrically insulative solid to partially fill the isolation trench and reduce an aspect ratio of the isolation trench from what it was prior to the flowing;
• and
• depositing an electrically insulative material to within the isolation trench over the insulative solid within the isolation trench.
