Publication number: 20240079360Abstract: A bonding structure for a semiconductor substrate and related method are provided. The bonding structure includes a first oxide layer on the semiconductor substrate, and a second oxide layer on the first oxide layer, the second oxide layer for bonding to another structure. The second oxide layer has a higher stress level than the first oxide layer, and the second oxide layer is thinner than the first oxide layer. The second oxide layer may also have a higher density than the first oxide layer. The bonding structure can be used to bond chips to wafer or wafer to wafer and provides a greater bond strength than just a thick oxide layer.Type: ApplicationFiled: September 6, 2022Publication date: March 7, 2024Inventors: Jorge A.

Patent number: 10520679Abstract: An optical system includes a photonics chip, a bridge waveguide structure formed on the chip, and an optical fiber disposed over the chip and optically aligned with the bridge waveguide structure. A cavity between the bridge waveguide structure and the chip is at least partially filled with an adhesive resin and a filler material having a coefficient of thermal expansion (CTE) less than that of the adhesive resin. The filler material may include filler particles dispersed throughout the adhesive resin, or a discrete layer of material separate from the adhesive resin. The composite adhesive material filling the cavity has an effective coefficient of thermal expansion less than the coefficient of thermal expansion of conventional adhesive resins. This lower effective CTE improves the survivability of the overlying bridge waveguide structure following thermal cycling of the optical system.Type: GrantFiled: June 5, 2018Date of Patent: December 31, 2019Assignee: GLOBALFOUNDRIES INC.Inventors: Sarah Knickerbocker, Jorge Lubguban, Tracy Tong

Patent number: 8574675Abstract: A method of forming a ruthenium-containing film in a vapor deposition process, including depositing ruthenium with an assistive metal species that increases the rate and extent of ruthenium deposition in relation to deposition of ruthenium in the absence of such assistive metal species. An illustrative precursor composition useful for carrying out such method includes a ruthenium precursor and a strontium precursor in a solvent medium, wherein one of the ruthenium and strontium precursors includes a pendant functionality that coordinates with the central metal atom of the other precursor, so that ruthenium and strontium co-deposit with one another. The method permits incubation time for ruthenium deposition on non-metallic substrates to be very short, thereby accommodating very rapid film formation in processes such as atomic layer deposition.Type: GrantFiled: March 17, 2010Date of Patent: November 5, 2013Assignee: Advanced Technology Materials, Inc.Inventors: Jorge A. Lubguban, Jr., Thomas M. Cameron, Chongying Xu, Weimin Li

Publication number: 20130181210Abstract: A layered heterostructure field effect transistor (HFET) comprises a substrate, a first semiconductor oxide layer grown on the substrate, and a second semiconductor oxide layer grown on the first layer semiconductor layer and having an energy band gap different from that of the first semiconductor layer, and the second layer also having a gate region and a drain region and a source region with electrical contacts to gate, drain and source regions sufficient to form a HFET. The substrate may be a material, including a single crystal material, and may contain a buffer layer material on which the first semiconductor layer is grown. The conductivity type of the first and second semiconductor layers and the composition of the semiconductor oxide layers can be selected to improve performance for desired operational features of the HFET. This layered structure can be applied for the improvement in the function and high frequency and high power performance of semiconductor HFET devices.Type: ApplicationFiled: October 29, 2008Publication date: July 18, 2013Applicant: MOXTRONICS, INC.Inventors: Yungryel Ryu, Tae-Seok Lee, Jorge Lubguban, Henry W.
