We developed a dual pixel with accurate and all-directional auto focus (AF) performance in CMOS image sensor (CIS). The optimized in-pixel deep trench isolation (DTI) provided accurate AF data and good image quality in the entire image area and over

2017 Symposium on VLSI Technology.
We present a CMOS image sensor (CIS) with phase detection auto-focus (PDAF) in all pixels. The size of photodiode (PD) is 0.64μm by 1.28μm, the smallest ever reported and two PDs compose a single pixel. Inter PD isolation was fabricated by deep tre

We introduced shallow-etched silicon nanowire into the arrayed waveguides to decrease the random phase error due to the core width fluctuation. A fairly improved crosstalk value of 18 dB was achieved in the fabricated arrayed-waveguide grating with t

We present a 10-Gb/s, 1×4 optical link based on a DRAM-integration-ready bulk-silicon modulator for multi-drop CPU-DRAM interconnects. The bulk-silicon modulator operated at 10 Gb/s on a die, and at 5 Gb/s in a QFP package. The 1×4 optical link was

We have fabricated a WDM device consisting of two or three shallow-etched AWGs on 5-inch SOI wafer. The center wavelength difference between the closely located AWGs was smaller than 1 nm. Meanwhile, the center wavelength deviation over the whole waf

The grating arms composed of silicon nanowires were shallow-etched to reduce the random phase error caused by the core width fluctuation. A fairly improved crosstalk value of 18 dB was achieved in the arrayed-waveguide grating with the on-chip loss o

We present a silicon nano-wire ring resonator with a temperature-dependent wavelength shift as low as 0.006 nm/degC by adjusting the mode volume of a SOl-based silicon waveguide covered with a polymeric material.
