Latest Patents

Among his latest patents, Kazuhisa Sasaki has developed several advanced technologies, including a transmitter, receiver, transmitter/receiver, and transmitting/receiving system. His work on this embodiment emphasizes preventing an increase in the number of cables for external interfaces, even as the variety of transmitted signals grows. Key components of his transmitter include a latch circuit that maintains the levels of multiple signals according to a specified sampling clock, subsequently outputting these signals as a parallel data signal. Following this, an encoder creates an encoded parallel data signal, which is then transformed into a serial data signal via a serializer. Notably, the sampling clock operates at a frequency that exceeds the transmission rate of the fastest signal within the system.

Another significant patent involves a semiconductor device and its fabrication method. This invention encompasses a semiconductor device featuring first and second conductive layers interconnected by a contact plug. The design includes a first insulating film, which has an opening reaching the first conductive layer's surface, and a second insulating film that also has an opening aligned with the first. The contact plug, filled in both openings, is noteworthy for having a surface level that is flush with the second insulating film, incorporating a metal characterized by a high melting point. Furthermore, the second conductive layer is formed on the insulating film and the contact plug.
