    摘要: An improved design for high aspect ratio MOS devices is capable of 100% yields. The design is suitable for low voltage CMOS devices, such as microprocessors, which use the high aspect ratio MOS devices in embedded applications, and for HEMTs in high frequency applications, such as high power microwave devices. The high yields reduce manufacturing costs. A modular MOS concept is introduced to realize the 100% yield of large channel width devices. The structure of the modular MOS device is a regular MOS device with a unit device channel width. This can be a multi-finger device which has a proper dimension to be able to fit in a given layout area. Therefore, the number of modules which are needed to form a full large width device is not only determined by module size, but also on the manufacturing yield record, allowed chip real estate and performance requirement.

    摘要: A method for forming a thin film, electrically blowable fuse with reproducible blowing wattage using a sacrificial metal patch over a fuse dielectric layer and two etch processes; wherein the first etch process is selective to the metal patch and the second etch process is selective to the fuse dielectric layer. A fuse element, having an element width, is formed over a semiconductor structure, and a fuse dielectric layer is formed over the fuse element. A sacrificial metal patch is formed on the fuse dielectric layer; wherein the patch width being greater than the fuse element width. A second dielectric layer is formed on the sacrificial metal patch, and additional metal layers and dielectric layers may be formed over the second dielectric layer, but only the dielectric layers will remain over the fuse element. The second dielectric layer and any overlying dielectric layers are patterned to form a fuse window opening, having a width greater than the sacrificial metal patch, using a first fuse window etch selective to the sacrificial metal patch. Then, the sacrificial metal patch is etched through the fuse window opening using a second fuse window etch selective to the fuse dielectric layer, leaving a reproducible thickness of the fuse dielectric layer overlying the fuse element; thereby providing a reproducible blowing wattage.

    摘要: A method for fabricating a metal-insulator-metal capacitor wherein top metal corner shaping during patterning is eliminated is described. An insulating layer is provided overlying a semiconductor substrate. A first metal layer is deposited over the insulating layer. A capacitor dielectric layer is deposited overlying the first metal layer. A second metal layer is deposited overlying the capacitor dielectric layer and patterned to form a top metal electrode. A flowable material layer is deposited overlying the capacitor dielectric and the top metal electrode and anisotropically etched away to leave spacers on sidewalls of the top metal electrode. A photoresist mask is formed overlying the capacitor dielectric and the top metal electrode wherein the spacers provide extra photoresist thickness at the sidewalls of the top metal layer. The capacitor dielectric layer and the first metal layer are patterned wherein the patterned first metal layer forms a bottom metal electrode and wherein the spacers protect the top metal layer from etching during the patterning. The photoresist mask is removed, completing fabrication of a metal-insulator-metal capacitor.
