POST-CMOS PROCESSING AND 3D INTEGRATION BASED ON DRY-FILM LITHOGRAPHY |
摘要 |
A method for performing a post processing pattern on a diced chip having a foot-print, comprises the steps of providing a support wafer; applying a first dry film photoresist to the support wafer; positioning a mask corresponding to the footprint of the diced chip on the first dry film photoresist; expose the mask and the first dry film photoresist to UV radiation; remove the mask; photoresist develop the exposed first dry film photoresist to obtain a cavity corresponding to the diced chip; positioning the diced chip inside the cavity; applying a second dry film photoresist to the first film photoresist and the diced chip; and expose and develop the second dry film photoresist applied to the diced chip in accordance with the post processing pattern. |
