The four probes were apposed on the via and connected each other with the backside nucleation layer.
After the pore filling, the backside seed layer can be removed by a polishing technique (Figure 2d).
After anodization, a simple backside seed layer deposited on the whole surface of the wafer ensures the metal electrochemical bottom-up filling (Figure 1b,c) [1b,c
The probes were apposed on the copper-filled macropores and connected each other, thanks to the remaining backside nucleation layer (Figure 8).
Retro-optical regenerate formation was completely abolished, while fibrosis was drastically reduced by the posterior capsule sandwiched in between the anterior LEC layer on the backside of the anterior capsule and the anterior optic surface, thereby blocking contact-mediated myofibroblastic LEC transdifferentiation.
In order to measure the effective lifetime of as-prepared SiNWs and α-Si H-covered SiNWs, 25-nm-thick Al2O3 layers were deposited on the backside of the wafers by the atomic layer deposition (ALD) method.
g Patterning and dry-etching of handle Si layer from the backside.
After the dry etching of the frontside, the PECVD-SiO2 layer on the backside of the wafer is dry etched to provide an oxide hard mask for deep reactive ion etching (DRIE) (Figure 6 e)).
The charge and discharge characteristic and the cycle performance of the resulting zinc-air battery were tested by the BTS-9000 batesty tesystemtem in a homemade metal-air battery model in air where air was introduced from the backside of the gas diffusion layer.
The SiN layer on the backside of the wafer was then patterned into a hard mask (HM) for subsequent TMAH etching, using photolithography followed by a reactive-ion etch to open 1 mm windows, completely removing the SiN in these regions.
Silicon substrate beneath the GaN grating region is patterned from backside and etched down to the AlN layer by DRIE, where the AlN layer serves as a definite etch stop (step e).
