Patent number: 8643187Abstract: An interconnection system is provided with reduced capacitance between a signal via and the surrounding dielectric material. By using a non-homogenous dielectric, the effective dielectric constant of the system is reduced. The signal vias are surrounded with some combination of open trenches and/or grounded vias to decrease the effective dielectric constant of the surrounding system, providing shielding from the interference of nearby signal lines and vias. The fabrication techniques provided are advantageous because they can be preformed using today's standard IC fabrication techniques.Type: GrantFiled: June 1, 2011Date of Patent: February 4, 2014Assignee: Banpil Photonics, Inc.Inventors: Achyut Kumar Dutta, Robert Olah

Publication number: 20120298411Abstract: An electronics interconnection system is provided with reduced capacitance between a signal line and the surrounding dielectric material. By using a non-homogenous dielectric, the effective dielectric constant of the material is reduced. This reduction results in less power loss from the signal line to the dielectric material, and therefore reduces the number of buffers needed on the signal line. This increases the speed of the signal, and reduces the power consumed by the interconnection system. The fabrication techniques provided are advantageous because they can be preformed using today's standard IC fabrication techniques.Type: ApplicationFiled: May 28, 2011Publication date: November 29, 2012Applicant: BANPIL PHOTONICS, INC.Inventor: ACHYUT KUMAR DUTTA
