  • Patent number: 12292687
    Abstract: In a method of pattern formation information including a pattern size on a reticle is received. A width of an EUV radiation beam is adjusted in accordance with the information. The EUV radiation beam is scanned on the reticle. A photo resist layer is exposed with a reflected EUV radiation beam from the reticle. An increase of intensity per unit area of the EUV radiation beam on the reticle after the adjusting the width is greater when the width before adjustment is W1 compared to an increase of intensity per unit area of the EUV radiation beam on the reticle after the adjusting the width when the width before adjustment is W2 when W1>W2.

  • Patent number: 12266703
    Abstract: An interconnect fabrication method is disclosed herein that utilizes a disposable etch stop hard mask over a gate structure during source/drain contact formation and replaces the disposable etch stop hard mask with a dielectric feature (in some embodiments, dielectric layers having a lower dielectric constant than a dielectric constant of dielectric layers of the disposable etch stop hard mask) before gate contact formation. An exemplary device includes a contact etch stop layer (CESL) having a first sidewall CESL portion and a second sidewall CESL portion separated by a spacing and a dielectric feature disposed over a gate structure, where the dielectric feature and the gate structure fill the spacing between the first sidewall CESL portion and the second sidewall CESL portion. The dielectric feature includes a bulk dielectric over a dielectric liner. The dielectric liner separates the bulk dielectric from the gate structure and the CESL.
