A method for fabricating a microelectronic fabrication employs an undoped silicate glass layer as an etch stop layer when etching a doped silicate glass layer with an anhydrous hydrofluoric acid etchant. The method is particularly useful for forming a patterned salicide blocking dielectric layer when fabricating a complementary metal oxide semiconductor device.

A new process is provided which is an extension and improvement of present processing for the creation of a solder bump. After the layers of Under Bump Metal and a layer of solder metal have been created in patterned and etched format and overlying the contact pad, following a conventional processing sequence, a layer of polyimide is deposited. The solder flow is performed using the thickness of the deposited layer of polyimide to control the height of the column underneath the reflown solder.

A high density interconnection device includes a high density connector block having a plurality of jacks disposed on the outer surface for common interconnected to a high density connector. A recessed portion formed on the first side surface defines a first multi-faceted surface having a plurality of angularly disposed first surface elements. A projecting portion formed on the second side surface defines a second multi-faceted surface having a plurality of angularly disposed second surface elements. In another embodiment, one group of jacks are defined in a first plane, and another group of jacks are defined in a second plane. The first and second planes are substantially parallel such that the first and second groups of jacks are offset.

A stencil design for solder paste printing, or other metal stencil printing, is disclosed. A stencil for stencil printing of solder onto a semiconductor wafer for semiconductor wafer bumping includes a substrate. The substrate has a hole defined therein substantially shaped to correspond to and receptive to the semiconductor wafer. An interior edge of the substrate surrounds the hole, and has an upper lip under which the semiconductor wafer is positioned. The upper lip of the interior edge of the substrate surrounding the hole substantially prevents the solder from flowing onto sides and a bottom of the semiconductor wafer during stencil printing of the solder. The cross-profile shape of the upper lip may in one embodiment be rectangular, whereas in another embodiment be triangular.
摘要:
A Ferris wheel-like stripping or cleaning mechanism that can be used in semiconductor fabrication, such as in photoresist or other stripping, or wafer or other cleaning, is disclosed. A stripping mechanism can include a container to hold a chemical, such as a photoresist stripping chemical, a wafer cleaning chemical, or another type of chemical. The mechanism can also include a component to move semiconductor wafers through the chemical in the container in a Ferris wheel-like motion. The component may include wafer holders for the wafers that are swivably mounted about an axis of rotation. As the one or more wafer holders rotate about the axis of rotation through the chemical in the container, the wafer holders remain in a substantially constant vertical and horizontal orientation.
摘要:
A method of forming a bump on a substrate such as a semiconductor wafer or flip chip. The method includes the act of providing a semiconductor device having a contact pad and having an upper passivation layer and an opening formed in the upper passivation layer exposing a portion of the contact pad. An under bump metallurgy is deposited over the upper passivation layer and the contact pad. An electrically conductive redistribution trace is deposited over the under bump metallurgy. A photoresist layer is deposited, patterned and developed to provide portions selectively protecting the electrically conductive redistribution trace and the under bump metallurgy. Excess portions of the electrically conductive redistribution trace and under bump metallurgy not protected by the photoresist are removed.
摘要:
A differential pressure indicator is provided for detecting and indicating a clogging condition of a filter element and subsequently an opening condition of a by-pass valve. The indicator also indicates when no filter element is installed in a fluid system. A thermal lockout effective even at high internal fluid differential pressure prevents false actuation of the indicating means at low temperatures due to increased viscosity of the system fluid. A positive locking feature prevents resetting of the indicating means after actuation. Servicing of the filter element is required in order to reset the indicator.
