Publication number: 20090146316Abstract: Disclosed are embodiments of a flip-chip assembly and method using lead-free solder. This assembly incorporates mushroom-plated metal layers that fill and overflow solder resist openings on an organic laminate substrate. The lower portion of metal layer provides structural support to its corresponding solder resist opening. The upper portion (i.e., cap) of each metal layer provides a landing spot for a solder joint between an integrated circuit device and the substrate and, thereby, allows for enhanced solder volume control. The additional structural support, in combination with the enhanced solder volume control, minimizes strain on the resulting solder joints. Additionally, the cap further allows the minimum diameter of the solder joint on the substrate-side of the assembly to be larger than the diameter of the solder resist opening. Thus, the invention decouples C4 reliability concerns from laminate design concerns and, thereby, allows for greater design flexibility.Type: ApplicationFiled: December 5, 2007Publication date: June 11, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Virendra R.

By laser irradiation using a femtosecond laser, when an amorphous semiconductor film over which a cap film is formed is crystallized with a laser, it becomes possible to perform crystallization of the semiconductor film and removal of the cap film at the same time. Therefore, a step of removing the cap film in a later step can be omitted.Type: ApplicationFiled: March 7, 2008Publication date: September 25, 2008Inventor: Takatsugu Omata

Publication number: 20080206957Abstract: The present invention relates to a method of forming an isolation layer of a semiconductor memory device. After a trench is formed by etching a semiconductor substrate, a liner insulating film is formed from a DCS-HTO material having a similar wet etch rate to that of a PSZ film that gap fills an isolation layer, and the trench is gap filled with the PSZ film. Accordingly, in a subsequent etch process for EFH control of the isolation layer, residues do not remain on sidewalls of a conductive film for a floating gate, thereby improving electrical properties of devices.Type: ApplicationFiled: December 5, 2007Publication date: August 28, 2008Applicant: HYNIX SEMICONDUCTOR INC.Inventors: Kwang Hyun Yun, Min Sik Jang
