Publication number: 20240332365Abstract: Various embodiments of wafers include a polycrystalline silicon carbide (SiC) layer or base substrate. The polycrystalline silicon carbide (SiC) layer may have a resistivity less than or equal to 2 mohm-cm (milliohm-centimeter) such that the polycrystalline silicon carbide layer is a low resistivity polycrystalline silicon carbide layer. The polycrystalline silicon carbide layer may have grains with a grain size less than or equal to 1 millimeter (mm), and may have a non-columnar structure. The polycrystalline silicon carbide layer may have a warpage less than or equal to 75 ?m (micrometers). A monocrystalline silicon carbide (SiC) layer may be coupled to the polycrystalline silicon carbide (SiC) layer by a bonding layer. The monocrystalline silicon carbide layer may be thinner than the polycrystalline silicon carbide layer.Type: ApplicationFiled: March 22, 2024Publication date: October 3, 2024Applicant: STMicroelectronics International N.V.Inventors: Björn MAGNUSSON LINDGREN, Carlo RIVA

POLYCRYSTALLINE SILICON CARBIDE SUBSTRATE WITH DENSITY GRADIENT AND METHOD OF MANUFACTURING THE SAME
Publication number: 20240332366Abstract: A polycrystalline silicon carbide (SiC) substrate with a density gradient between a first side of the polycrystalline SiC substrate and a second side of the polycrystalline SiC substrate opposite to the first side. A first density at the first side of the polycrystalline SiC substrate is less than a second density at the second side of the polycrystalline SiC substrate. The polycrystalline SiC substrate with the density gradient may be formed by forming a polycrystalline SiC base substrate with a sintering process followed by a post-sintering process. For example, the post sintering process may be at least one of the following of: applying a first temperature to the first side and a second temperature to the second side of the polycrystalline SiC substrate and performing a chemical vapor deposition (CVD) process to impregnate further silicon (Si) and carbon (C) atoms into the polycrystalline SiC base substrate.Type: ApplicationFiled: March 22, 2024Publication date: October 3, 2024Applicant: STMicroelectronics International N.V.Inventors: Björn MAGNUSSON LINDGREN, Carlo RIVA -
Publication number: 20240332011Abstract: At least one embodiment of a method of manufacturing includes forming a first polycrystalline silicon carbide (SiC) substrate with a sintering process by sintering one or more powdered semiconductor materials. After the first polycrystalline SiC substrate is formed utilizing the sintering process, the first polycrystalline silicon carbide SiC substrate is utilized to form a second polycrystalline SiC substrate with a chemical vapor deposition (CVD) process. The second polycrystalline SiC substrate is formed on a surface of the first polycrystalline SiC substrate by depositing SiC on the surface of the first polycrystalline SiC substrate with the CVD process. As the first and second polycrystalline SiC substrates are made of the same or similar semiconductor material (e.g., SiC), a first coefficient of thermal expansion (CTE) for the first polycrystalline SiC substrate is the same or similar to the second CTE of the second polycrystalline SiC substrate.Type: ApplicationFiled: March 22, 2024Publication date: October 3, 2024Applicant: STMicroelectronics International N.V.Inventors: Björn MAGNUSSON LINDGREN, Alexandre ELLISON, Carlo RIVA

Patent number: 11842333Abstract: A payer transaction device enables secure offline transactions using a secure element providing a secure payer account database, a secure ledger database, and a wallet application. While the payer transaction device is not connected to the Internet, the wallet application receives a payee identifier and a transaction amount and verifies that the transaction amount is less than an available payer account balance in the secure payer account database. In response, the wallet application creates a digital token that allocates the transaction amount from the payer account balance to the payee identifier, and records the digital token in a payer secure ledger in the secure ledger database, which reduces the available payer account balance by the transaction amount. The wallet application then transfers the digital token to a payee transaction device over a peer-to-peer wireless connection and, subsequently, the digital token is synchronized with a ledger tracking system through the Internet.Type: GrantFiled: October 20, 2020Date of Patent: December 12, 2023Assignee: PAYPAL, INC.Inventors: Satish Narayan Govindarajan, Anantharaj Uruthiralingam, Carlos Rivas, Srikanth Nandiraju
