摘要:
A method of fabricating a mask read-only memory. Before carrying out a code implantation, a coding mask is used as an etching mask to remove a portion of the inter-metal dielectric layer and the inter-layer dielectric layer above the coding positions, thereby forming a contact window. The code implantation is subsequently carried out so these ions can easily reach the coding positions via the contact opening.

The present disclosure relates to a device and method for fabricating a semiconductor memory device arrangement comprising a butted a contact arrangement configured to couple two transistors, wherein an active area of a first transistor is coupled to an active gate of a second transistor. The active gate of the second transistor is formed from a gate material which comprises a dummy gate of the first transistor, and is configured to straddle a boundary between the active area of the first transistor and an isolation layer formed about the first transistor. The butted a contact arrangement results in a decreased contact resistance for the butted contact as compared to previous methods.

A metal-oxide-metal capacitor comprises a first electrode, a second electrode, a plurality of first fingers and a plurality of second fingers. Each first finger and its corresponding second finger are in parallel and separated by a low k dielectric material. A via-hole region is employed to enclose the metal-oxide-metal capacitor so as to remove the moisture stored in the low k dielectric material.

A method of reliability testing of a semiconductor device is described. The embodiment, includes providing a capacitor including an insulating layer interposing two conductive layers. A plurality of voltages are provided to the capacitor including providing a first voltage and a second voltage greater than the first voltage. A leakage associated with the capacitor is measured while applying the second voltage. In an embodiment, the leakage measured while applying the second voltage indicates that a failure of the insulating layer of the capacitor has occurred. In an embodiment, the capacitor is an inter-digitated metal-oxide-metal (MOM) capacitor. The reliability testing may be correlated to TDDB test results. The reliability testing may be performed at a wafer-level.

A new method is provided for the creation of a hole through a layer of insulating material. The method provides for combining a feed-forward method with a feed backward method and a high-polymer based hole profile, in order to establish a hole of a constant Critical Dimension for the hole bottom, making the CD of the hole bottom independent of the CD of the opening created through the overlying developed layer of photoresist and independent of the thickness of the layer of insulator material after CMP has been applied to the surface of the insulation layer.

A method of fabricating a dual-oxide STI comprising the following steps. A structure having an STI opening formed therein is provided. An HDP silicon oxide layer portion is formed within the STI opening, partially filling the STI opening. A planarized HDP silicon-rich-oxide cap layer is formed upon the HDP silicon oxide layer portion, filling the STI opening to form the dual-oxide STI, whereby any unlanded contact window formed through an overlying interlevel dielectric layer exposing a portion of the dual-oxide STI only exposes a portion of the HDP silicon-rich-oxide cap layer.
