==General Photolithography Techniques==

====[[Photolithography - Improving Adhesion Photoresist Adhesion|'''HMDS Process for Improving Adhesion''']]====

*''Use these procedures if you are finding poor adhesion PR lifting-off), or for chemicals (like BHF) that attack the PR adhesion interface strongly.''

====[[Photolithography - Manual Edge-Bead Removal Techniques|'''Edge-Bead Removal Techniques''']]====

*''These techniques are required for loading full-wafers into etchers that use top-side clamps, to prevent photoresist from sticking to the clamp (and potentially destroying your wafer).''
*''For contact lithography, this improves the proximity of the mask plate and sample, improving resolution. For some projection systems, such as the [[Maskless Aligner (Heidelberg MLA150)|Maskless Aligner]], EBR can help with autofocus issues.''

====[https://www.microchemicals.com/technical_information/reflow_photoresist.pdf '''Photoresist reflow (MicroChem)''']====

*''To create slanted sidewalls or curved surfaces.''
[[Lithography Calibration - Analyzing a Focus-Exposure Matrix|'''Lithography Calibration - Analyzing a Focus-Exposure Matrix''']]

* ''On tools with autofocus (steppers & direct-write litho tools), you calibrate your litho by shooting a "Focus Exposure Matrix/Array", or "FEM/FEA", which exposes a grid with Dose varying in one axis, and Focus varying in the other.''
* ''Explains how to locate the'' ''"Process Window" for your lithography.''

**''Uses multiple DUV Flood exposure/develop cycles to create undercut.''

==[[Automated Coat/Develop System (S-Cubed Flexi)|Automated Coat/Develop System Recipes (S-Cubed Flexi)]]==
Recipes pre-loaded on the S-Cubed Flexi automated coat/bake/develop system. Only staff may write new recipes, contact the tool supervisor for more info.

===Available Variations===

*We have different recipes with varyious UV6 spin speeds - the same spin speed optionss as found on our manual Headway spinners. This allows for PR thickness control. See the linked UV6 datasheets below for thickness vs. rpm spin curves. '''Note''' that exact spin RPM may be slightly different between Headway spinners (on benches) vs. S-Cubed.
*DSK is recommended to be spun at 1.5krpm (~40nm) for best anti-reflection properties. 5krpm (~20nm) recipes are also provided for historical/legacy processes.
*DSK can be baked at either 220C to act as a Dry-etchable BARC (similar to DUV-42P), or at lower temps as a developable BARC (no dry etch required).
*"Chain" recipes (with DSK+UV6 spin/cured in succession) are only available for DSK Baked at 185C & 220C, and all UV6 Spin-speed variations. For the other DSK temps you can use the single-PR "Routes".
*Developer recipes are now available for 300 MiF Developer. '''Note''' that developer is flowing continuously during the develop, so <u>develop times are shorter by ~50%</u> compared to beaker developing.
**'''DO NOT EDIT developer recipes''', they can damage the tool when programmed incorrectly!
*"Chain" recipes for 135*C Post-exposure Bake + Develop have been made.
*ASML cassettes can be placed directly on this tool for spin / exposure / develop process. Please make sure all cassettes are kept back at their respecting tools when done.

DSK101 spun at 1.5K is equivalent to DUV-42P. See: [[Stepper Recipes#Anti-Reflective Coatings]]

'''185°C bake''' allows the DSK to dissolve during develop, and allows for undercut (may lift-off small features)

'''220°C bake''' allows DSK to be used as dry-etchable BARC (equiv. to DUV42P), requiring O2 etch to remove. Better for small features. See [[Stepper Recipes#Anti-Reflective Coatings|here for relevant processing info from DUV42P]].

General Photolithography Techniques

HMDS Process for Improving Adhesion

  • Use these procedures if you are finding poor adhesion PR lifting-off), or for chemicals (like BHF) that attack the PR adhesion interface strongly.

Edge-Bead Removal Techniques

  • These techniques are required for loading full-wafers into etchers that use top-side clamps, to prevent photoresist from sticking to the clamp (and potentially destroying your wafer).
  • For contact lithography, this improves the proximity of the mask plate and sample, improving resolution. For some projection systems, such as the Maskless Aligner, EBR can help with autofocus issues.

Photoresist reflow (MicroChem)

  • To create slanted sidewalls or curved surfaces.

Lithography Calibration - Analyzing a Focus-Exposure Matrix

  • On tools with autofocus (steppers & direct-write litho tools), you calibrate your litho by shooting a "Focus Exposure Matrix/Array", or "FEM/FEA", which exposes a grid with Dose varying in one axis, and Focus varying in the other.
  • Explains how to locate the "Process Window" for your lithography.

Lift-Off Recipes

E-Beam Lithography Recipes (JEOL JBX-6300FS)

  • Under Development.

FIB Lithography Recipes (Raith Velion)

To Be Added

Automated Coat/Develop System Recipes (S-Cubed Flexi)

Recipes pre-loaded on the S-Cubed Flexi automated coat/bake/develop system. Only staff may write new recipes, contact the tool supervisor for more info.

Available Variations

  • We have different recipes with varyious UV6 spin speeds - the same spin speed optionss as found on our manual Headway spinners. This allows for PR thickness control. See the linked UV6 datasheets below for thickness vs. rpm spin curves. Note that exact spin RPM may be slightly different between Headway spinners (on benches) vs. S-Cubed.
  • DSK is recommended to be spun at 1.5krpm (~40nm) for best anti-reflection properties. 5krpm (~20nm) recipes are also provided for historical/legacy processes.
  • DSK can be baked at either 220C to act as a Dry-etchable BARC (similar to DUV-42P), or at lower temps as a developable BARC (no dry etch required).
  • "Chain" recipes (with DSK+UV6 spin/cured in succession) are only available for DSK Baked at 185C & 220C, and all UV6 Spin-speed variations. For the other DSK temps you can use the single-PR "Routes".
  • Developer recipes are now available for 300 MiF Developer. Note that developer is flowing continuously during the develop, so develop times are shorter by ~50% compared to beaker developing.
    • DO NOT EDIT developer recipes, they can damage the tool when programmed incorrectly!
  • "Chain" recipes for 135*C Post-exposure Bake + Develop have been made.
  • ASML cassettes can be placed directly on this tool for spin / exposure / develop process. Please make sure all cassettes are kept back at their respecting tools when done.

Recipes Table (S-Cubed Flexi)

Ask Staff if you need a new recipe.
Coating Material Route/Chain Name: (User: "UCSB Users") Spin Speed (krpm) Bake Temp Notes
BEFORE LITHOGRAPHY (PR Coat and Bake)
Hotplate Set Route To pre-set the DSK Hotplate temp (HP4).

Note: Only HP4 can be changed.

HP1-HP3 remains fixed at: HP1=135°C, HP2=170°C & HP3=170°C

HP4-SET-220C 220°C Will over shoot +-2°C when done.
HP4-SET-210C 210°C
HP4-SET-200C 200°C
HP4-SET-185C 185°C
Bottom Anti-Reflection Coating (BARC), DSK101 only:
DS-K101 Route DSK101 Develop Rate depends on Bake temp - you can use this to control undercut. See: DSK Bake vs. Dev rate

DSK101 spun at 1.5K is equivalent to DUV-42P. See: Stepper Recipes#Anti-Reflective Coatings

185°C bake allows the DSK to dissolve during develop, and allows for undercut (may lift-off small features)

220°C bake allows DSK to be used as dry-etchable BARC (equiv. to DUV42P), requiring O2 etch to remove. Better for small features. See here for relevant processing info from DUV42P.

Note: All PR coat recipes have EBR backside clean steps included in the recipe.
