A method for electromagnetically shielding circuits which combine to form an integrated circuit device provides isolated silicon islands surrounded laterally and subjacently by conductive material. The isolated silicon islands may be covered individually or as a group by a conductive cover. The integrated circuit may include at least one silicon island including an analog circuit and at least one silicon island including a digital circuit, the analog and digital circuits electromagnetically shielded from one another. The method for forming the structure includes providing a first semiconductor substrate and hydrophilically bonding a substructure to the first semiconductor substrate. The substructure includes the isolated silicon islands surrounded by the conductive material. The substructure may be formed on a second semiconductor substrate by implanting an impurity region into an upper portion of the second semiconductor substrate. After bonding, the substructure may be separated from the remainder of the second substrate by propagating a crack along the boundary of the impurity region which separates the substructure from the remainder of the second semiconductor substrate. The method further includes forming the conductive cover over the isolated silicon island or islands by forming insulating layers over the silicon islands then forming a conductive cover layer and conductive sidewalls to surround the silicon island or islands being enclosed.

A phase shift mask and a fabrication method thereof are used in a semiconductor light exposing process, where a CD (Critical Dimension) formed on a wafer is the same in all directions, even when a pattern is arranged on the mask at an anisotropic pitch. The phase shift mask includes a number of light transmitting regions and first and second phase shift regions arranged among the light transmitting regions. The first and second phase shift regions have a refractive index different from that of the light transmitting region. The first and second phase shift regions also have a transmittance different from each other.

Methods and apparatuses to design an Integrated Circuit (IC) with a shielding of wires. In at least one embodiment of the present invention, a shielding mesh of at least two reference voltages (e.g., power and ground) is used to reduce both the capacitive coupling and the inductive coupling in routed signal wires in IC chips. In some embodiments, a type of shielding mesh (e.g., a shielding mesh with a window surrounded by a power ring, or a window with a parser set of shielding wires) is selected to make more routing area available in locally congested areas. In other embodiments, the shielding mesh is used to create or add bypass capacitance. Other embodiments are also disclosed.
摘要:
A semiconductor device that has a common border between P and N wells is susceptible to photovoltaic current that is believed to be primarily generated from photons that strike this common border. Photons that strike the border are believed to create electron/hole pairs that separate when created at the PN junction of the border. The photovoltaic current can have a sufficient current density to be destructive to the metal connections to a well if the area of these metal connections to the well is small relative to the length of the border. This photovoltaic current can be reduced below destructive levels by covering the common border sufficiently to reduce the number of photons hitting the common border. The surface area of the connections can also be increased to alleviate the problem.

The CDM protection circuit comprises a plurality of CDM protection devices that are electrically connected to one another, and a grounded conductive pad electrically connected to one CDM protection device, the CDM protection devices including a plurality of dummy devices such as dummy metals in tapered shape. The CDM protection devices are distributed over the internal device region in a manner to achieve a global protection of the IC against CDM charges by absorbing and dissipating the CDM charges. To increase CDM protection, a capacitor is further disposed in a manner to surround the internal device region.

Two adjacent lines are formed in parallel to a signal line in a wiring layer where the signal line is formed. Intersection lines are formed respectively in wiring layers above and under the wiring layers where the signal line and the adjacent lines are formed, along areas which are enclosed by the adjacent lines. Entire-line-area through-holes for connecting each of the adjacent lines with a corresponding one of the intersection line are formed along the entire area of the adjacent lines, in an insulating layer between the adjacent lines and the intersection lines. The signal line is completely covered by the adjacent lines, the intersection lines and the entire-line-area through-holes. The adjacent lines, the intersection lines and the entire-line-area through-holes are maintained at a constant potential, or their electric potentials have the same phase as that of the signal line.
摘要:
A method of shielding an integrated circuit from electromagnetic interference. The integrated circuit is at least partially encapsulated within an electromagnetic interference resistant molding compound, and then the integrated circuit is completely encapsulated within a second molding compound. In this manner, the electromagnetic interference resistant molding compound protects the integrated circuit from electromagnetic interference, while the second molding compound can be selected for properties traditionally desired in a molding compound, such as thermal, electrical insulating, and structural properties. Thus, the integrated circuit according to the present invention can be placed closer to structures, such as power supplies, which produce electromagnetic interference, without experiencing an unacceptable degradation of performance due to the electromagnetic interference caused by the structures.
