Abstract:
A crack stop (28) for low K dielectric materials of an integrated circuit (IC) formed on an IC chip using metal interconnects which do not form a self-passivating oxide layer, such as copper or silver interconnects, in a low-K dielectric material to prevent damage to the active area of the IC chip caused by chipping and cracking formed along peripheral edges of the IC chip during a dicing operation. A moisture barrier or edge seal (12) is formed as a metal stack positioned along the outer peripheral edges of the active area of the IC chip. The crack stop is formed by at least one trench or groove positioned outside of the moisture barrier/edge seal on the outer periphery of the IC chip.
Abstract:
PROBLEM TO BE SOLVED: To provide a metal-insulator-metal capacitor having improved manufacturing possibility, and to provide a method for fabricating the same. SOLUTION: A semiconductor structure including the vertical metal-insulator-metal capacitor, and a method for fabricating the semiconductor structure including the vertical metal-insulator-metal capacitor, each use structural components from a dummy metal oxide semiconductor field effect transistor located and formed over an isolation region located over a semiconductor substrate. The dummy metal oxide field effect transistor may be formed simultaneously with a metal oxide semiconductor field effect transistor located over a semiconductor substrate that includes the isolation region. The metal-insulator-metal capacitor uses a gate as a capacitor plate, a uniform thickness gate spacer as a gate dielectric and a contact via as another capacitor plate. The uniform thickness gate spacer may include a conductor layer for enhanced capacitance. A mirrored metal-insulator-metal capacitor structure that uses a single contact via may also be used for enhanced capacitance. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
A method for forming preferably Pb-lead C4 connections or capture pads with ball limiting metallization on an integrated circuit chip by using a damascene process and preferably Cu metallization in the chip and in the ball limiting metallization for compatibility. In two one embodiment, the capture pad is formed in the top insulating layer and it also serves as the final level of metallization in the chip.
Abstract:
Semiconductor devices are fabricated in a strained layer region and strained layer-free region of the same substrate. A first semiconductor device, such as a memory cell, e.g. a deep trench storage cell, is formed in a strained layer-free region of the substrate. A strained layer region is selectively formed in the same substrate. A second semiconductor device (66, 68, 70), such as an FET, e.g. an MOSFET logic device, is formed in the strained layer region.

Abstract:
PROBLEM TO BE SOLVED: To provide CMOS image sensor pixel sensor cells, methods for fabricating the pixel sensor cells, and design structures for fabricating the pixel sensor cells. SOLUTION: The CMOS image sensor cells are designed to allow for back side illumination in global shutter mode by providing light shielding from back side illumination of at least one transistor within each pixel sensor cell. In a first particular generalized embodiment, a light blocking layer is located and formed interposed between a first semiconductor layer including a photoactive region and a second semiconductor layer including at least a second transistor or a floating diffusion region shielded by the light blocking layer. In a second generalized embodiment, a thin film transistor and a metal-insulator-metal capacitor are used in place of the floating diffusion region, and are arranged, shielded in a dielectric-isolated metallization stack over a carrier substrate.
