Non-epitaxial electrical coupling between a front side trench connector and back side contacts of a transistor

A package comprising:

• an electrical component;
• a transistor electrically coupled with the electrical component, the transistor comprising:
• a front side and a backside opposite the front side;
• a fin;
• a first trench connector at the front side of the transistor;
• a second trench connector and a third trench connector at the backside of the transistor, the third trench connector distinct from and laterally spaced apart from the second trench connector;
• a connector directly electrically coupling the first trench connector with the second trench connector, wherein the connector comprises metal, and wherein the connector has a bottom surface at a same level as a bottom surface of the fin, the bottom surface of the connector in direct contact with the second trench connector, and the bottom surface of the fin in direct contact with the third trench connector.
