# How can I calculate/estimate the resistance of the thin film structured like in the picture (top view)?

let's say the thin film is made of metal with resistivity rho and thickness t.

I need to calculate the sheet resistance between point A and B.

any reference suggestion is really appreciated.

• can't. how far apart are the diamonds? – Jasen May 31 '18 at 8:38
• rough estimate: disregard the diamonds, juist calculate the 3 rectangles front-to-back. better estimate: previous one, plus 6 x the triangle with cut top from the vertical through A up to the junction with the first rectangle. Seems doable with calculus. Even better: calculate the A and B triangles up to the connection with their rectangles separately, to account for the one-point connections. No idea how to do that. – Wouter van Ooijen May 31 '18 at 9:20
• @Jasen, I edit the picture. the distance between the diamonds is h. – Codelearner777 May 31 '18 at 10:15
• I think I found a way to calculate that. I will post it later. – Codelearner777 Jun 7 '18 at 10:36
