Publication number: 20010000245Abstract: An improved structure and method for gated lateral bipolar transistors is provided. The present invention capitalizes on opposing sidewall structures and adjacent conductive sidewall members to conserve available surface space on the semiconductor chips. The conserved surface space allows a higher density of structures per chip. The conductive sidewall members couple to the gate of the gated lateral bipolar transistor and, additionally, to a retrograded, more highly doped bottom layer. The improved structure provides for both metal-oxide semiconductor (MOS) type conduction and bipolar junction transistor (BJT) type conduction beneath the gate of the gated lateral bipolar transistor.Type: ApplicationFiled: December 6, 2000Publication date: April 12, 2001Applicant: Micron Technology, Inc.Inventors: Leonard Forbes, Wendell P.

Publication number: 20010000246Abstract: A dielectric etch process applicable etching a dielectric layer with an underlying stop layer. It is particularly though not necessarily applicable to forming a dual-damascene interconnect structure by a counterbore process, in which a deep via is etched prior to the formation of a trench connecting two of more vias. A single metallization fills the dual-damascene structure. The substrate is formed with a lower stop layer, a lower dielectric layer, an upper stop layer, and an upper dielectric layer. For example, the dielectric layers may be silicon dioxide, and the stop layers, silicon nitride. The initial deep via etch includes at least two substeps. A first substep includes a non-selective etch through the upper stop layer followed by a second substep of selectively etching through the lower dielectric layer and stopping on the lower stop layer. The first substep may be preceded by yet another substep including a selective etch part ways through the upper dielectric layer.Type: ApplicationFiled: December 1, 2000Publication date: April 12, 2001Inventors: Betty Tang, Jian Ding
