摘要： Methods and apparatus are described that reduce the possibility that unintended subway short-circuits will occur between contacts of different potentials along the boundary between tensile and compressive liners (the T-C boundary). This may be done without unduly increasing the size of the semiconductor device, or even increasing the size at all over previous designs. For example, simply by adjusting the layout of the device, the contacts of two different common gates may be offset in opposing directions relative to the T-C boundary. Or, by forming a T-C boundary having a zigzag or other similar pattern, the contacts may be arranged even closer together while still reducing the likelihood of short-circuiting subways forming. Such layout adjustments do not otherwise require any additional steps or cost.
摘要翻译：描述了减少在拉伸和压缩衬里（T-C边界）之间的边界处的不同电位的触点之间发生意外的地铁短路的可能性。这可以在不过度增加半导体器件的尺寸的情况下进行，或者甚至在以前的设计中增加尺寸。例如，简单地通过调整装置的布局，两个不同公共栅极的触点可以相对于T-C边界相反的方向偏移。或者，通过形成具有锯齿形或其他类似图案的T-C边界，可以将触点设置得更靠近在一起，同时仍然减少了地铁短路形成的可能性。这样的布局调整不需要额外的步骤或成本。

摘要： In a semiconductor device, a wiring pattern groove is formed in a surface portion of a silicon oxide film provided above a semiconductor substrate. A wiring layer is buried into the wiring pattern groove with a barrier metal film interposed therebetween. The barrier metal film is selectively removed from each sidewall portion of the wiring pattern groove. In other words, the barrier metal film is left only on the bottom of the wiring pattern groove. Thus, a damascene wiring layer having a hollow section whose dielectric constant is low between each sidewall of the wiring pattern groove and each side of the wiring layer can be formed in the semiconductor device.

摘要： First and second wirings are formed on a first insulating film. Each of the wirings is arranged so that a conductive film, a silicon oxide film and a silicon nitride film are laminated. Thereafter, a silicon oxide insulating film is formed on the whole surface. The silicon oxide insulating film is etched so that a contact hole is formed between the first and second wirings. Since the silicon oxide film and the silicon nitride film exist on the conductive film of each wiring, the conductive film is not exposed at the time of etching. Thereafter, an insulating film is formed on a side wall of the contact hole, and the conductive film exposed through the contact hole is covered by the insulating film.

An insulating film (e.g., a silicon nitride film) is provided on the sides of each trench of the interlayer insulator. A storage electrode made of ruthenium or the like is provided in each trench of the interlayer insulator. A capacitor insulating film made of BSTO or the like is formed on the storage electrode. A plate electrode made of ruthenium or the like is formed on the capacitor insulating film. The plate electrode is common to all capacitors provided. Any two adjacent capacitors are electrically isolated by the interlayer insulator and the insulating film provided on the sides of the trenches of the interlayer insulator.

摘要： Disclosed is a method of forming an element isolation insulating film by STI (shallow trench isolation) method, which permits effectively preventing a concave portion from being formed in an edge of the element isolation insulating film, permits decreasing the number of treating steps, and also permits facilitating the formation of the element isolation insulating film with a high yield. In forming the element isolation insulating film, a groove is formed in a surface region of a semiconductor substrate, followed by forming an insulating film on the entire surface to fill at least the groove. Then, a flattening treatment is applied at least once to remove the insulating film from the substrate surface such that the insulating film is left unremoved only within the groove. In place of a wet etching treatment, a mirror-polishing method is employed for the last flattening treatment.

摘要： A semiconductor memory device comprises a semiconductor substrate, a first conducting layer formed above the main surface of the semiconductor substrate, a second conducting layer formed above the first conducting layer through a first insulating layer and connected to the first conducting layer through a first via-conductor formed in a first contact hole formed in the first insulating layer, and a third conducting layer formed beneath the second conducting layer through a second insulating layer and connected to the second conducting layer through a second via-conductor formed in a second contact hole formed in the second insulating layer, in which an angle formed by a tangent to an inner wall of the first contact hole and a normal to the first conducting layer at a portion of the first conducting layer at which the first contact hole is in contact with the first conducting layer, is larger than an angle formed by a tangent to an inner wall of the second contact hole and a normal to the third conducting layer at a portion of the third conducting layer at which the second contact hole is in contact with the third conducting layer. By virtue of this structure, it is possible to avoid influence of electrical potential variation upon the first conducting layer in the manufacturing process.
