摘要： Disclosed are embodiments of a capacitor with inter-digitated vertical plates and a method of forming the capacitor such that the effective gap distance between plates is reduced. This gap width reduction significantly increases the capacitance density of the capacitor. Gap width reduction is accomplished during back end of the line processing by masking connecting points with nodes, by etching the dielectric material from between the vertical plates and by etching a sacrificial material from below the vertical plates. Etching of the dielectric material from between the plates forms air gaps and various techniques can be used to cause the plates to collapse in on these air gaps, once the sacrificial material is removed. Any remaining air gaps can be filled by depositing a second dielectric material (e.g., a high k dielectric), which will further increase the capacitance density and will encapsulate the capacitor in order to make the reduced distance between the vertical plates permanent.
摘要翻译：公开了具有数字化的垂直板的电容器的实施例以及形成电容器的方法，使得板之间的有效间隙距离减小。该间隙宽度减小显着增加了电容器的电容密度。通过用节点掩蔽连接点，通过从垂直板之间蚀刻电介质材料，并通过从垂直板下方蚀刻牺牲材料，在线加工的后端完成间隙宽度减小。一旦牺牲材料被去除，介质材料之间的介电材料的蚀刻形成气隙，并且可以使用各种技术来使板在这些气隙上塌陷。可以通过沉积第二电介质材料（例如，高k电介质）来填充任何剩余的气隙，这将进一步增加电容密度并封装电容器，以使得垂直板之间的距离减小。

摘要： A method for forming a transmission line structure for a semiconductor device includes forming an interlevel dielectric layer over a first metallization level, removing a portion of the interlevel dielectric layer and forming a sacrificial material within one or more voids created by the removal of the portion of the interlevel dielectric layer. A signal transmission line is formed in a second metallization level formed over the interlevel dielectric layer, the signal transmission line being disposed over the sacrificial material. A portion of dielectric material included within the second metallization level is removed so as to expose the sacrificial material, wherein a portion of the sacrificial material is exposed through a plurality of access holes formed through the signal transmission line. The sacrificial material is removed so as to create an air gap beneath the signal transmission line.

摘要： A polysilicon containing resistor includes: (1) a p dopant selected from the group consisting of boron and boron difluoride; and (2) an n dopant selected from the group consisting of arsenic and phosphorus. Each of the p dopant and the n dopant has a dopant concentration from about 1e18 to about 1e21 dopant atoms per cubic centimeter. A method for forming the polysilicon resistor uses corresponding implant doses from about 1e14 to about 1e16 dopant ions per square centimeter. The p dopant and the n dopant may be provided simultaneously or sequentially. The method provides certain polysilicon resistors with a sheet resistance percentage standard deviation of less than about 1.5%, for a polysilicon resistor having a sheet resistance from about 100 to about 5000 ohms per square.

摘要： The invention is directed to an integrated circuit comb capacitor with capacitor electrodes that have an increased capacitance between neighboring capacitor electrodes as compared with other interconnects and via contacts formed in the same metal wiring level and at the same pitches. The invention achieves a capacitor that minimizes capacitance tolerance and preserves symmetry in parasitic electrode-substrate capacitive coupling, without adversely affecting other interconnects and via contacts formed in the same wiring level, through the use of, at most, one additional noncritical, photomask.

摘要： A three-dimensional micro- electromechanical (MEM) varactor is described wherein a movable beam and fixed electrode are respectively fabricated on separate substrates coupled to each other. The movable beam with comb-drive electrodes are fabricated on the “chip side” while the fixed bottom electrode is fabricated on a separated substrate “carrier side”. Upon fabrication of the device on both surfaces of the substrate, the chip side device is diced and “flipped over”, aligned and joined to the “carrier” substrate to form the final device. Comb-drive (fins) electrodes are used for actuation while the motion of the electrode provides changes in capacitance. Due to the constant driving forces involved, a large capacitance tuning range can be obtained. The three dimensional aspect of the device avails large surface area. When large aspect ratio features are provided, a lower actuation voltage can be used. Upon fabrication, the MEMS device is completely encapsulated, requiring no additional packaging of the device. Further, since alignment and bonding can be done on a wafer scale (wafer scale MEMS packaging), an improved device yield can be obtained at a lower cost.
