Patent number: 8951836Abstract: A method for forming a chip package, in which a substrate has a plurality of conducting pads located below its lower surface, and a dielectric layer located between the conducting pads. A hole is formed extending from the upper surface of the substrate towards the conducting pads. After the hole is formed, a trench is formed extending from the upper surface towards the lower surface of the substrate, with the trench connecting with the hole. An insulating layer is formed on a sidewall of the trench and a sidewall and a bottom of the hole, and a portion of the insulating layer and a portion of the dielectric layer are removed to expose a portion of the conducting pads. A conducting layer is formed on the sidewall of the trench and the sidewall and the bottom of the hole, electrically contacting with the conducting pads.Type: GrantFiled: March 14, 2014Date of Patent: February 10, 2015Assignee: Xintec, Inc.Inventors: Yu-Lin Yen, Chien-Hui Chen, Tsang-Yu Liu, Long-Sheng Yeou

Patent number: 8928098Abstract: A semiconductor package includes: a chip having a first portion and a second portion disposed on the first portion, wherein the second portion has at least a through hole therein for exposing a portion of the first portion, and the first portion and/or the second portion has a MEMS; and an etch stop layer formed between the first portion and the second portion and partially exposed through the through hole of the second portion. The invention allows an electronic element to be received in the through hole so as for the semiconductor package to have integrated functions of the MEMS and the electronic element. Therefore, the need to dispose the electronic element on a circuit board as in the prior art can be eliminated, thereby saving space on the circuit board.Type: GrantFiled: December 13, 2012Date of Patent: January 6, 2015Assignee: Xintec, Inc.Inventors: Hung-Jen Lee, Shu-Ming Chang, Tsang-Yu Liu, Yen-Shih Ho

Patent number: 8624351Abstract: A package structure which includes a non-conductive substrate, a conductive element, a passivation, a jointed side, a conductive layer, a solder and a solder mask is disclosed. The conductive element is disposed on a surface of the non-conductive substrate and consists of a passive element and a corresponding circuit. The passivation completely covers the conductive element and the non-conductive substrate so that the conductive element is sandwiched between the passivation and the non-conductive substrate. The conductive layer covers the jointed side which exposes part of the corresponding circuit, extends beyond the jointed side and is electrically connected to the corresponding circuit. The solder mask which completely covers the jointed side and the conductive layer selectively exposes the solder which is disposed outside the jointed side and electrically connected to the conductive layer.Type: GrantFiled: May 27, 2011Date of Patent: January 7, 2014Assignee: Xintec, Inc.Inventors: Chien-Hung Liu, Shu-Ming Chang
