E-beam line dose of hsq

WebVoids were generally observed at the bottom of the HSQ line. Size and quantity of voids are larger for lower W/L ratios, indicating that the voids were formed due to insufficient HSQ volume for gap-filling. Increasing e-beam dose, baking or reflow temperature, and reflow of ZEP520A before HSQ coating could reduce the void formation. WebA method of forming a semiconductor device includes: forming a semiconductor feature over a substrate, the semiconductor feature includes a conductive region; forming a dielectric layer over the semiconductor feature; patterning the dielectric layer to form a contact opening exposing a top surface of the conductive region; forming a monolayer over the …

WebFeb 13, 2012 · HSQ pillar CD resolution on LTO HM is higher than that on LTN HM. Smallest CD of HSQ pillar is 23.1 nm. Fogging effect is strong for TBLC-100PM where e-beam dose could affect the shape of HSQ pillar of neighboring array. This is not observed for AR3-600 UL. HSQ pillar CD resolution is highest for HSQ coated at 2000 rpm. WebHSQ resist is a high resolution negative tone resist that has excellent etch resistance. Lithography can be performed with E-beam, EUV or SFIL. We offer HSQ pre-diluted and filtered in MIBK, however we also have the option of a ‘dry-kit’. This consists of HSQ powder in a vial, a measure of MIBK and a syringe and syringe filter.
