Title: Deposited spacer structure and method of forming the same
Inventor: YANG CHIH-HSIEN
IPC: H01L29/49
Filed: 2002-05-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a spacer structure for a stacked layer composed of an electrically conductive layer and a cap layer formed on a semiconductor substrate, wherein the structure has improved electrical isolation and low coupling capacitance.   <P>SOLUTION: A spacer structure is deposited on the sidewall of a stacked layer composed of an electrically conductive layer and a cap layer thereon. A dielectric layer composed of a material having a lower dielectric constant than that of silicon nitride is formed covering the semiconductor substrate. Then, a first silicon nitride layer is formed covering the substrate. The first silicon nitride layer and the dielectric layer are sequentially etched so as to form an inner spacer on the sidewall of the stacked layer. A second silicon nitride layer is formed covering the substrate to form an outer spacer on the sidewall of the inner spacer. By forming a deposited spacer structure in which a low-dielectric-constant material is buried, the coupling capacitance generated therein is greatly reduced.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-05-28
Abstract: <P>PROBLEM TO BE SOLVED: To prevent defective mounting, etc., of an electronic component.   <P>SOLUTION: A foot pattern 200 is so formed that the area S2 of a part 202 outer than an expected position A-A' of its end surface if an electronic component is fixed at a proper position be larger than the area S1 of a part 201 inner than the expected position (S1<S2). The length L2 of the outer part 202 is formed larger than the length L1 of the inner part 201 (L1<L2). Since the centripetal force of a surface tension acts on both end surfaces of an electronic component when melting a solder, so that a self-alignment effects acts appropriately and a defective mounting of the electronic component is prevented. The amount of a solder to be applied to the inner part 201 is reduced to prevent bridging on the lower surface of the electronic component. A tester is easy to touch the foot pattern for easy inspection of products.  <P>COPYRIGHT: (C)2004,JPO
