    摘要: A method for forming a semiconductor device comprises forming a first layer over a semiconductor substrate. At least one hole is formed through the first layer. A bottom anti-reflective coating (BARC) layer is formed in the at least one hole. A first heating is performed to heat the BARC layer to a flow temperature. A second heating is performed to heat the BARC layer to a hardening temperature so that the BARC layer hardens, wherein the hardening temperature is greater than the flow temperature. An etch is performed to form a trench in the first layer and over the at least one hole, wherein the hardened BARC layer in the at least one hole acts as an etch resistant layer during the etch. As an alternative to the second heating step, the BARC may be simply hardened. The first and second heating may be performed within a heating chamber without removing the semiconductor substrate.

    摘要: There is provided a method of making a dual inlaid via in a first layer. The first layer may be a polymer intermetal dielectric, such as HSQ, of a semiconductor device. The method includes forming a first opening, such as a via, in the first layer and forming an inorganic base radiation sensitive layer in the first opening. The radiation sensitive layer may be a polysilane imaging layer. The inorganic base radiation sensitive layer is selectively exposed to radiation and then patterned. A second opening, such a trench, is formed in communication with the first opening using the patterned inorganic base radiation sensitive layer as a mask. A conductive layer may be formed in the dual inlaid via to complete a dual damascene process.

    摘要: A method is provided for fabricating a T-gate structure. A structure is provided that has a silicon layer having a gate oxide layer, a polysilicon layer over the gate oxide layer, and an ARC layer over the polysilicon layer. A gate structure is formed by removing the ARC layer and a portion of the polysilicon layer around a gate region. Spacers are then formed around the gate structure. Undercut regions are formed in the gate structure by performing an isotropic etch to provide the gate structure with a base region and a contact region. The base region has a width smaller than the contact region.
