    摘要: A structure, a method of fabricating and a method of using a phase shift mask (PSM) having a first phase shifted section, a half tone section, and a second phase shifted section. The first phase shift section and the half tone section are shifted 180 degrees with the second phase shift region. Embodiments provide for (1) a half tone, single trench alternating phase shift mask and (2) a half tone, dual trench alternating phase shift mask. The half tone region provides advantages over conventional alternating phase shift masks.

    摘要: A reticle structure and a method of forming a photoresist profile on a substrate using the reticle having a multi-level profile. The reticle comprises (1) a transparent substrate, (2) a partially transmitting 180 degree phase shift film overlying predetermined areas of the transparent substrate to transmit approximately 20 to 70% of incident light, and (3) an opaque film overlying the predetermined areas of the partially transmitting 180 degree phase shift film. The method comprises the following steps: a) depositing a photoresist film over the substrate; b) directing light to the photoresist film through the reticle, and c) developing the photoresist film to form an opening in the resist layer where light only passed thru the substrate, and to remove intermediate thickness of the photoresist film, in the areas where the light passed through the partially transmitting 180 degree phase shift film. In an aspect, the photoresist film is comprised of a lower photoresist layer and an upper photoresist layer. The lower photoresist layer is less sensitive to light than the upper photoresist layer. In an aspect, the resist profile is used to form a dual damascene shaped opening.

    摘要: A method and structure for removing side lobes is provided by positioning first and second radiation transparent regions of respective first and second phases at a first plane with the first and second phases being substantially out of phase. Further, positioning the first and the second region to cause radiation at a second plane to be neutralized in a first region, not to be neutralized in a second region, and to have a side lobe in a third region. Further, positioning a non-transparent region at the first plane to assure radiation at the second plane to be neutralized in the first region and positioning a third radiation transparent region of the first or second phase at the first plane to neutralize the side lobes in the third region at the second plane.

    摘要: A method for forming a contact hole unit cell is provided. A light transparent contact hole region of a first phase is positioned at a first plane. A light transparent phase-shifting region of a second phase is positioned at the first plane, the second phase being substantially out of phase with the first phase. The phase-shifting region substantially surrounds the contact hole region. A light transparent border region is positioned at the first plane outside the phase-shifting region. The border region has a phase substantially the same as that of the contact hole region. A chrome pad is positioned at the first plane outside and contacting at least a portion of the border region. The contact hole region, the phase-shifting region, the border region, and the chrome pad are positioned to cause light from the first plane to be reinforcing in a target contact hole configuration on a second plane and to be substantially neutralizing outside the target contact hole configuration on the second plane.
