Abstract
Abstract An improved method and apparatus for forming a plasma-polymerized methylsilane (PPMS) photo-sensitive resist material includes the steps of pressurizing the chamber to between about 1 to about 2 Torr, heating the substrate to between about 50 DEG C. and about 200 DEG C., and plasma-polymerizing the precursor methylsilane gas to deposit a stable film having high-photosensitivity at high deposition rates.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
94 words
A process for depositing a photo-sensitive resist layer on a substrate disposed in a substrate processing chamber, said process comprising the steps of: (a) establishing a selected process pressure in said chamber; (b) providing thermal energy to heat said substrate to temperature of between about 50° C. and about 200° C.; after steps (a) and (b), flowing a precursor gas of methylsilane into said chamber; and providing electromagnetic energy to said electrode to strike a plasma to plasma-polymerize said precursor gas of methylsilane and to deposit a plasma-polymerized methylsilane (PPMS) layer on said substrate.
Claim 2
Dependent Claim
94 words
A process for depositing a photo-sensitive resist layer on a substrate disposed in a substrate processing chamber, said process comprising the steps of: (a) establishing a selected process pressure in said chamber; (b) providing thermal energy to heat said substrate to temperature of between about 50° C. and about 200° C.; after steps (a) and (b), flowing a precursor gas of methylsilane into said chamber; and providing electromagnetic energy to said electrode to strike a plasma to plasma-polymerize said precursor gas of methylsilane and to deposit a plasma-polymerized methylsilane (PPMS) layer on said substrate.
Claim 3
Dependent Claim
27 words
The process of claim 1 further comprising establishing a process pressure of between about 1 Torr and about 2 Torr driving the deposition of said PPMS layer.
Claim 4
Dependent Claim
76 words
A process for depositing a photo-sensitive resist layer on a substrate disposed in a substrate processing chamber, said process comprising: (a) establishing a selected process pressure in said chamber of between about 1 Torr and about 2 Torr; flowing a precursor gas of methylsilane into said chamber; and providing electromagnetic energy to said electrode to strike a plasma to plasma-polymerize said precursor gas of methylsilane and to deposit a plasma-polymerized methylsilane (PPMS) layer on said substrate.
Claim 5
Dependent Claim
76 words
A process for depositing a photo-sensitive resist layer on a substrate disposed in a substrate processing chamber, said process comprising: (a) establishing a selected process pressure in said chamber of between about 1 Torr and about 2 Torr; flowing a precursor gas of methylsilane into said chamber; and providing electromagnetic energy to said electrode to strike a plasma to plasma-polymerize said precursor gas of methylsilane and to deposit a plasma-polymerized methylsilane (PPMS) layer on said substrate.
Claim 6
Dependent Claim
15 words
The process of claim 3 wherein said process pressure is between 1 and 2 Torr.
Claim 7
Dependent Claim
28 words
The process of claim 3 further comprising heating said substrate to a temperature of between about 50° C. and about 200° C. during deposition of said PPMS layer.
Claim 8
Dependent Claim
151 words
A process for depositing a photo-sensitive resist layer on a substrate disposed in a substrate processing chamber, said process comprising: (a) establishing a process pressure in the chamber of between about 1 Torr and about 2 Torr; (b) providing thermal energy to heat said substrate to a temperature of between about 50° C. and about 200° C.; (c) flowing a precursor gas of methylsilane into a reaction zone of the chamber; (d) providing electromagnetic energy to an electrode of the chamber to strike a plasma from said methylsilane precursor gas; and (e) after steps (a) through (d), maintaining the chamber at a process pressure of between about 1 Torr and about 2 Torr, maintaining said substrate at a temperature of between about 50° C. and about 200° C., maintaining said flow of methylsilane and maintaining said plasma to deposit a plasma-polymerized methylsilane (PPMS) layer having a selected thickness over said substrate.
Claim 9
Dependent Claim
151 words
A process for depositing a photo-sensitive resist layer on a substrate disposed in a substrate processing chamber, said process comprising: (a) establishing a process pressure in the chamber of between about 1 Torr and about 2 Torr; (b) providing thermal energy to heat said substrate to a temperature of between about 50° C. and about 200° C.; (c) flowing a precursor gas of methylsilane into a reaction zone of the chamber; (d) providing electromagnetic energy to an electrode of the chamber to strike a plasma from said methylsilane precursor gas; and (e) after steps (a) through (d), maintaining the chamber at a process pressure of between about 1 Torr and about 2 Torr, maintaining said substrate at a temperature of between about 50° C. and about 200° C., maintaining said flow of methylsilane and maintaining said plasma to deposit a plasma-polymerized methylsilane (PPMS) layer having a selected thickness over said substrate.
