Sony patents light-emitting chip design with protective film

Patent drawing from the official filing.

Sony describes a light-emitting device where a thin film is placed on the side of the chip substrate. This film sits between the light-emitting component and the lens to protect the base material after the chip is cut from a larger sheet.

Why it mattersThis is a routine manufacturing improvement that helps protect delicate electronic components during production, which is standard practice in chipmaking.

In the filing’s own words

[Problem] The present disclosure provides a light-emitting apparatus capable of suitably protecting a substrate after singulation and a manufacturing method thereof. [Solution] A light-emitting apparatus according to the present disclosure includes: a substrate; a light-emitting element provided on a first surface of the substrate; a lens provided on a second surface of the substrate; and a film provided on a third surface between the first surface and the second surface of the substrate.

What exactly they claim (claim 1)

1. A light-emitting apparatus, comprising: a substrate; a light-emitting element provided on a first surface of the substrate; a lens provided on a second surface of the substrate; and a film provided on a third surface between the first surface and the second surface of the substrate.
