US Patent:

42683483, May 19, 1981

Filed:

Aug 1, 1966

Appl. No.:

4/569368

Inventors:

David F. Allison - Palo Alto CA
David A. Maxwell - San Jose CA

Assignee:

Signetics Corporation - Sunnyvale CA

International Classification:

H01L 2122
H01L 21304
H01L 21308

US Classification:

156645

Abstract:

1. In a method for forming a semiconductor structure utilizing a semiconductor body, forming a grid structure in the semiconductor body, forming a support structure upon the grid structure, removing only a portion of the semiconductor body to provide a semiconductor body which has a substantially uniform thickness in the vicinity of the grid structure and in which the grid structure does not intercept the exposed surface of the semiconductor body, and forming additional grid structure in the semiconductor body joining the first named grid structure so that islands of semiconductor material are formed in the semiconductor body which are isolated from each other and from the support structure. 23. In a method for forming a semiconductor structure utilizing a semiconductor body having a surface, forming a layer of insulating material on the surface of the semiconductor body, forming a recessed grid in the layer of insulating material and extending into the semiconductor body, forming a layer of insulating material on the recessed grid adhering to said surface and having a depth which is insufficient to fill the recessed grid to form a grid structure in a semiconductor body prior to the formation of a semiconductor device in the semiconductor body, forming a support structure upon the grid structure, removing a portion of the semiconductor body and diffusing isolation fences into the semiconductor body which extend and make contact with the layer of insulating material to form a plurality of islands of semiconductor material isolated from each other and from the support structure.

Appl. No.:

17/836846

Inventors:

- San Francisco CA, US
Brian Grassadonia - San Francisco CA, US
Lauren A. Myrick - San Francisco CA, US
David W. Maxwell - San Francisco CA, US

International Classification:

G06Q 40/00

Abstract:

Disclosed herein is a technology for automatically triggering delivery of a digital receipt for one or more financial transactions based on a change in location of the user or a time. In at least some embodiments, the technology includes a payment system detecting a change in location of a user or a change in time and determining, based on the change, that a payment transaction has occurred. The payment system then causes presentation of digital receipt for the payment transaction on a mobile device of a customer.

David W. Maxwell - San Francisco CA, US

International Classification:

G06Q 40/00

Abstract:

Disclosed herein is a technology for automatically triggering delivery of a digital receipt for a financial transaction based on a previously stored electronic address for receiving digital receipts. In at least some embodiments, the technology includes a digital receipt system working in coordination with one or more merchants' POS device to deliver receipts for current transactions based on a previously stored electronic address from past transactions. The first time a user utilizes a payment card in a transaction, the system associates and stores a user-provided electronic address with the card. The next time the user utilizes the card in a new transaction, the system identifies the card has been used in a past transaction, determines the electronic address associated with the card, and automatically triggers receipt delivery to the electronic address, regardless of the new transaction being with a same or different merchant than the one in the past transaction.
