SEMICONDUCTOR DEVICE AND METHOD OF PRODUCING HIGH CONTRAST IDENTIFICATION MARK |
摘要 |
<p>A seconductor device (50) includes a semiconductor die (20) having a first surface (14) for forming electronic circuitry. A coating layer (16) formed on a second surface (15) of the semiconductor die has a color that contrasts with the color of the semiconductor die. The coating layer is patterned to expose a portion of the second surface to reveal information pertaining to the semiconductor device. The coating layer is patterned by directing a radiation beam (30) such as a laser to selectively remove material from the coating layer.</p> |
